Rodger® Wireless Alarm Troubleshooting Guide

1. How do I set up the Rodger® alarm for my child to use?

First, attach the outlet plug on the back of the receiver, then plug it into an outlet. Next, pair the transmitter and receiver by pressing the central LED button on the receiver, which will light up green. Then press the – and + buttons simultaneously for 3 seconds. The central button will start blinking green and you have one minute to connect the two snaps of the transmitter with the metal strip on the front of the receiver. They are paired when the LED lights up green and the receiver gives a short beep.

Extra receivers are paired to the transmitter in the same way. Have your child put on the sensor briefs and snap the transmitter onto the studs at the waistband.

2. How do I test the Briefs for my Rodger® Wireless alarm to confirm that they sense moisture correctly?

First, take a cup of LUKEWARM water, and mix in a teaspoon of salt. Clip the transmitter onto the sensor brief and plug the Receiver unit into an outlet and turn it on. Pour a small amount of the saltwater mixture onto the front of the briefs (approximately 2 teaspoons). This should cause the alarm to sound. **Briefs become more absorbent after washing, so testing before washing for the first time may require more saltwater.

3. What type of underwear should my child wear?

The Rodger® Wireless alarm comes with two pairs of sensor briefs that must be worn in order for the alarm to sense moisture. Regular underwear/briefs are not required.

4. How do I know what size briefs to order with my child’s Rodger® Alarm?

Please view the size conversion chart on our website for sizing information.

5. Can I purchase additional briefs with my Rodger® Alarm?

Yes, additional briefs can be purchased for $19.95 each. Some parents prefer to have an extra pair or two to reduce the frequency of laundry loads.

6. Can I use the Rodger® Wireless alarm with pull-ups or Good Night products?

Using a pull-up or other disposable pant product is not recommended when wearing the Rodger® alarm. The use of a pull-up increases the chances that the Transmitter unit worn on the underwear will be flooded with urine, which may cause it to malfunction. Secondly, it is very difficult to monitor progress, especially as your child reduces the amount he wets, when a pull-up is worn over the briefs.

7. How do I test my Rodger® Wireless alarm to confirm that it is working?

First, turn on the Receiver (wall unit) and plug it into an outlet. The green light should shine constantly. Then, holding the Transmitter box, place a metal object (such as a kitchen knife) across the two snaps on the back of the transmitter box and hold until the Receiver unit begins to sound (approximately 1-2 seconds). The Receiver sounding indicates that the alarm is working properly. Press the reset button on the Receiver to turn the sound off

8. All of the outlets in my child’s bedroom are covered by furniture and are difficult to access. How can I plug my Receiver in?

Many parents find that using a short power strip or extension cord makes the Receiver much more accessible for turning on and off/resetting, etc. You can also use batteries in the receiver rather than plugging it in. Do not use batteries and wall outlet at same time - use one or the other.

9. How do I improve the chances that my child will awaken when the alarm sounds?

Make sure that the volume on the Receiver is turned up to a high volume and that there are no objects or materials blocking the outlet it is plugged into. In addition, it is important to note that most children are very sound sleepers, and will require the assistance of a parent/caregiver to wake up to the alarm. Therefore, it is important that an adult can hear the alarm so that he/she can assist the child in waking up.

10. How long will the alarm sound after it has been activated?

The Rodger® Wireless alarm will continue to sound until you or your child presses the Reset button on the Receiver wall unit. This requires your child to get up and out of bed to turn the alarm off, rather than simply pushing a button on the shoulder and falling back to sleep.

11. How do I turn the alarm off after it starts sounding?

After the alarm is triggered by moisture, turn the sound off by pressing the reset button on the Receiver (wall unit). This will require your child to get out of bed.

12. How long do the batteries last?

Battery drain is minimal in the Transmitter unit, as it only transmits when moisture is detected. This battery, therefore, should last for several months. If you choose to use batteries in the Receiver rather than using outlet power, these batteries will last for approximately one month. This may vary significantly depending upon the amount of time that the Receiver is actually switched ON. If you use batteries, do not leave the Receiver on during the day as this will quickly drain the batteries. Additionally, do not use batteries while plugging the Receiver into the wall outlet; use either the batteries or wall plug, not both. We recommend plugging the Receiver into a wall outlet rather than using batteries, as this will cut down on costs and maintenance.

13. Where can I find replacement batteries for the receiver?

Replacement AAA batteries can be found locally at any grocery store or other store that carries common batteries. Bedwetting Store if you have trouble finding them elsewhere.

14. I am getting false alarms. The Receiver is sounding even though the briefs are dry. What can I do?

You may be getting wireless interference from another wireless device. Try turning off your wireless internet, cordless phone or other devices one by one and see if you can identify the source of interference. Occasionally these devices may cause false alarms with your Rodger® system. You may need to temporarily turn off your wireless internet, or source during the night in these instances. Trying a different outlet in the room may even change the amount of wireless interference. During the day, turn off the receiver unit that is plugged into the wall. Remember that wireless interference in your own home is not a defect in the alarm, but something that you may need to accommodate for the few weeks that your child will need to use the alarm. Try re-pairing the alarm as this may also decrease interference.

15. I tested my alarm and it worked, but it did not sound when my child wet his bed. What should I do?

There are several things that may have caused the alarm not to sound:


  • First, check to make sure that the Receiver is turned ON and that the volume is turned up.
  • Check to make sure that your Receiver is plugged into a working outlet (if it is a switched outlet, make sure that the switch is turned on).
  • Make sure that the Receiver is only running on one power source – if this wall unit has batteries installed AND it is plugged into a wall outlet, it will not function properly. Either remove the batteries or unplug the unit from the wall.
  • Make sure that there are no other transmitting devices, such as a baby monitor, interfering with the Rodger® alarm. If other devices are in use, try changing their frequency or relocating them to prevent interference.
  • The sensor threads in the underwear can initially come over starched. Additionally, the underwear can become coated with residue over time. To freshen them, soak in Oxyclean or a solution of 1 part vinegar to 1 part water.

16. Can the Rodger® Transmitter box get wet?

While the Transmitter unit will sustain moisture from general wetting, it should be kept as dry as possible, and is not designed to sustain major flooding damage. Therefore, REMEMBER TO REMOVE THE TRANSMITTER FROM YOUR CHILD’S UNDERWEAR BEFORE LAUNDERING.

17. How do I clean my Rodger® Wireless alarm and sensor?

The Rodger® briefs can be machine washed and dried on a low setting. DO NOT wring the briefs, as this will damage the sensing mechanism. To clean the Transmitter unit, simply wipe with a damp cloth and let air dry. DO NOT PUT THE TRANSMITTER UNIT IN THE WASHING MACHINE.

18. I accidentally put my Transmitter in the washing machine. Can I buy just that piece?

Yes, a new transmitter can be purchased for the newer circular Rodger® alarm and paired with your receiver.

19. The first time we used the Rodger® Wireless alarm it worked fine, but it didn’t work when we tried to use it again. What does this mean?

Often, this just indicates that the Receiver was turned off after the initial activation and was not turned back on before using the alarm again. Make sure you push the center button so the green LED light shines. If the light is yellow, it means a low battery so it should be replaced. You should also try repairing the transmitter and receiver.

20. I just started using my Rodger® Wireless alarm again after storing it for several months, and now it isn’t working. How can I fix it?

Here are the main reasons an alarm stops working:

1.  The battery life has expired in the transmitter (smaller one)

2.  The battery was replaced but inserted incorrectly.

3.  The alarm receiver is not synced (paired) with the alarm transmitter (not communicating)   

4.  The transmitter was flooded (water or urine got inside)

Let's assume the transmitter battery life has expired and you need to replace it. (You will need a CR32 battery)

1. Open the back of the transmitter. (newer style transmitters have a turn-style back in which a nickel can be used to twist it open, the older style transmitters have two screws on the back (in some cases one of the screws may be covered with a sticker).  *If you have an older model transmitter (opens with 2 screws on the back) then it is important to make sure that the battery is in the correct way.

2.  The correct way to put the battery into an "old style" transmitter is to slide the battery in without smashing down the little metal "fingers" on the sidewall of the battery chamber. (Look at the picture below and notice the metal fingers in the bottom red circle) The tiny metal "fingers" need to be kept in the up position so they look the way they do in the picture below. Place the battery in with the writing facing up.  

3. Push the battery in and replace the back cover.

4. The final step is to pair or sync the alarm. (See steps below)

  • Plug in the receiver into an outlet and press the central LED button, which will light it up green. Then press the – and + buttons on the either side of the green light simultaneously for 3-5 seconds. (Note: If you do not press them at the exact same time the unit will start alarming, if this happens turn it off then on again and try again)
  • The central button will start blinking green and you have about one minute to touch the two metal snaps of the transmitter (small one) directly onto the metal strip (that says Rodger) on the front of the receiver. 
  • They are paired when the LED lights up green and the receiver gives a short beep. Once it is paired, you will not have to re-pair every time, it should stay paired. (Note: If you try to pair it and it never gives a solid beep but starts to alarm instead, try again hold both metal snaps directly on the metal Rodger strip for 3-8 seconds) 
  • If you never get the solid beep telling you it is paired, you may have a flooded transmitter

21. Does the Rodger® Wireless alarm play more than one sound?

Yes, the alarm makes 8 different sounds. Select the sound of your choice by pressing the SELECT-button. The last selected sound will be heard every time the alarm goes off. For each alarm to be a different sound, Press the AUTO-button. Each time the alarm goes off, 1 of the 8 available sounds will be heard.

22. My child does not wake up when his alarm goes off. Does this mean the alarm won’t work for him?

Many children who wet the bed are such sound sleepers that they cannot initially respond to an alarm on their own. This does not mean that they will be unsuccessful with the alarm. It is important that if your child does not hear the alarm on her own, that you help her wake up when the alarm goes off.

23. What is the warranty on the Rodger® Wireless alarm?

The Rodger® Wireless alarm is covered by a manufacturer’s warranty for 1 year from the date of receipt by the original purchaser. This warranty covers defects in manufacturing or materials, but does not apply to batteries and battery covers. This warranty does not cover misuse or abuse of the alarm. The briefs have a 6 month warranty. Warranty service is provided directly by the Bedwetting Store.

24. After three months use, my briefs are not as sensitive. One has stopped sensing moisture completely - although the alarm works fine. What is wrong?

Over time, residue may build up on the sensor contacts inside your brief and reduce the ability to quickly detect moisture or cause it to stop sounding. This may be due to your water, detergent or urine - or a combination of these factors. The same issue occurs with most other alarms, too. You simply need to soak the sensor briefs in vinegar or OxyClean solution to restore their sensitivity. Follow the steps below:

  • Fill a bowl with approximately 3 cups of warm water
  • Add either 1 cup of vinegar or 1/2 cup of OxyClean
  • Place brief(s) in the solution and let sit for 1 hour
  • Remove briefs from solution and launder and dry. Do Not Wring Dry.

25. How do I replace the batteries for a transmitter with 2 hexagonal screws?

To change the CR2032 battery in the Rodger® Transmitter:

  1. Use a 1.5 mm hex screwdriver to remove the two rivets from the back of the transmitter. One of the rivets may be under a sticker.
  2. Remove the old battery by gently lifting it out of the battery compartment, taking care not to damage the short prongs visible that are holding the battery in place.
  3. Slide the new battery, positive side up, UNDER the short prongs that can be seen opposite the longer prongs. Press the battery in place.
  4. Replace the back cover and the rivets.
  5. Pair the transmitter to the receiver: attach the outlet plug on the back of the receiver, then plug it into an outlet, OR use batteries (do not insert batteries if the receiver is plugged into the wall). Next, pair the transmitter and receiver by pressing the central LED button on the receiver, which will light up green. Then press the – and + buttons simultaneously for 3 seconds. The central button will start blinking green and you have one minute to connect the two snaps of the transmitter with the metal strip on the front of the receiver. They are paired when the LED lights up green and the receiver gives a short beep.
