Malem Wireless Bedwetting Alarm

1. My alarm doesn’t sound. What should I check?

Turn the receiver (large unit) on. A red LED light will flash. Replace the batteries with 2 new AA Alkaline ones. Be sure to observe the polarity markings.

Does the transmitter (the small unit) red LED light glow through the plastic casing when the lever on the Easy-Clip is pressed down? If not, replace the battery (A23 12V).

To remove the back of the transmitter: Hold the transmitter with the easy clip sensor down toward the floor. The front of the transmitter should be in the palm of your hand and the back half with the clear strap facing you. Pull the clear plastic strap down tight over the magnetic block. You should see a slight space between the magnetic block and a “slider piece” of green plastic with a larger space above. Slide a small screwdriver into this space. Push the “slider piece” up or twist gently and the two pieces should start to come apart. Use your fingernail or screwdriver to gently pry the pieces apart.

Please note: When replacing the batteries in the transmitter, it is very important to preserve the rubber seal and make sure it is in position when the back of the unit is replaced. When replacing the back, hook the bottom edge in first, then swing the small door into place. The unit can become flooded with urine if the seal is not in proper position.

If replacing the batteries does not solve the problem, re-tune the receiver and transmitter. (See instructions below).

2. The receiver unit seems to sound when moisture is not present. Why would this be?

Your alarm may be picking up wireless interference. The easiest way to avoid interference from other wireless equipment is to change the channel. A choice of 64 settings is possible.

To change the channel: Remove the back of the transmitter (the small unit). Follow the directions for removing the back of transmitter that are noted above. Change the setting of the code selection switch by moving any of the switches in any of the 64 combinations. (See page 4 of the yellow instruction booklet). Then replace the back of the transmitter. Now that you have changed the channel of the transmitter, you should re-tune the receiver so that both are using the same frequency.

Re-tune (Pairing up) the receiver: Push the straight end of a paper clip into the small hole at the back of the receiver (the large unit) under the green LED. The green LED will glow. Lower the lever of the Easy-Clip sensor (without material) on the small transmitter unit. The green LED will flash and the alarm will sound. Now lift the lever of the Easy-Clip sensor and press the reset button on the top of the receiver (the large unit). The receiver and transmitter are now automatically re-tuned again.

3. My alarm does not reset and turn off when I lift the lever and push the reset button. What should I do?

First, clean the Easy-Clip sensor by lifting the lever, washing the mouth of the sensor (where it comes in contact with the urine) with soapy water on an old toothbrush, rinse and gently shake dry.

Replace the receiver (large unit) batteries. (2 AA) Make sure the underpants’ material is not too thin or wet. Has the transmitter become damaged or flooded with urine? If so, it will need to be replaced. Flooding is not covered under the manufacturer’s warranty but the small transmitter can be purchased as a replacement part.
