DRI Sleeper bedwetting alarm unit size: 60 x 40 x 15mm (2.25 x 1.5 x 0.5 inches) Safety electronics (see below). Max alerting sound (we use the sound that wakes the best). Volume control (we set it to max - the control is internal so your child can't change it). How to use All it takes is 4 easy steps: Put the DRI Sleeper alarm unit on the shoulder of pyjamas or a T-shirt using the fastening provided. Put the Urosensor in the underwear (inside a minipad is best). Run the lead inside the pyjamas or T-shirt up to the shoulder. Plug the Urosensor lead into the DRI Sleeper alarm unit. Treatment is now ready to begin! It is completely moulded and easy to clean and dry for instant reuse. The Urosensor goes inside the underpants right where the urine hits. Its soft and flexible - no hard plastic clips or domes. There are no metal contacts and so it can't corrode or deteriorate in urine. There are nine pairs of sensing strips on BOTH sides for maximum detection. The DRI Sleeper Excel special electronics and electrolysis prevention When an alarm is triggered by urine it starts beeping. But what most people don't know, is that with most alarms, all the time that the alarm is beeping, there is an electric current passing through the sensor. Even although the current is very small, it can cause the urine to become acidic (called electrolysis) and that can irritate sensitive skin. But the DRI Sleeper Excel is different, as soon as the Urosensor is wet by urine, it triggers the DRI Sleeper Excel alarm, it starts beeping, and instantly the special alarm electronics isolate the Urosensor, and no more current passes through the Urosensor.
