■Parts Description & Function ①LED Indicator indicates conditions of transmitter. ②Sensor Jack connects tape adapter or sensor pad. ③Battery Case holds 2 AAA batteries. ④Battery Case Cover AAA) R03 AAA) R03 （ （ Sensor Adapter Wetness Sensor (Sensor Side) Apply this surface to the diaper with double-faced tape. ●If the wrong side is applied, the sensor does not work properly.
■How to Set-Up Sensor Adapter Snap fastener for fixing the Sensor Tape LED will blink when it is set correctly. Insert the plug into the jack all the way until the terminal latches into the transmitter's receptor. ■How to Set-Up Sensor Tape Install the sensor adapter to the sensor tape as below. Please make sure that the snap fasteners touch the electrodes; otherwise, it may not sense wetness. Electrodes CAUTION ●Attach the side of the tape to the snap fastener.
■How to Set-Up Sensor Pad Insert the plug into the jack all the way until the plug latches into the transmitter's receptor. ●Attaching the terminal upside down will cause an error. After connection, make sure LED is blinking. CAUTION LED will blink when it is set correctly ■How to Apply to the Diaper Attach the sensor side of the pad to the diaper. Keep the sensor string from touching skin. 2. Wrap the diaper with its side cover and fasten with Velcro fastener. Fold back the transmitter on the cover.

■Parts Description & Function ③Operation Indicator ①Antenna Keep the antenna straight up for better reception ②Receiving Indicator illuminates for receiving Wet Signal from transmitter You can check that the receiver is working when the red light blinks at every 1.5 sec. When low battery, red light blinks at every 1 sec. . ④Power Switch ON to use. OFF to quit or to reset the sensor. ⑤Alarm Mode Switch Knob switches between vibration, low alarm, and high alarm.
P-9 ■Can Not Detect Wetness ●Transmitter Problem？ Does LED blink? If no, check batteries and every connection. Do batteries have power? Check LED and change batteries. Are you operating within the range? Keep the distance between the transmitter and receiver within 160ft, when use. Is the battery case broken? If yes, call service department for repair. Is the transmitter case broken? If yes, call service department for repair.
P-10 ●Sensor Pad Problem? Sensor pad is broken? Change the sensor pad. Using the sensor pad over one month? Change the sensor pad. Check where is wet. Apply the sensor pad where gets wet. Sensor pad is apart from the diaper. Fix the side of sensor pad on to the outer surface of the diaper firmly with double-faced tape. ■The sensor comes on when the diaper is actuary dry ●Transmitter problem? Is it wet near the snap fastener? If yes, use after dry the hook. Use slow dry method.
