Make new holes on tape every installation. Reusing holes may cause an error. Electrodes CAUTION CAUTION CAUTION How to Apply to Diaper Using Sensor Tape 2. Wrap the diaper with its side cover and fasten with Velcro fastener. Fold back the transmitter on the cover. 1. Apply the sensor tape between two layers of cloth diaper. Face the blue side of the sensor tape to skin. Facing the wrong side may cause an error. The sensor tape is only for one time use. Discard the used tape as combustible. 3. Wrap with the center cover. How to Set-Up Sensor Pad Insert the plug into the jack all the way until the plug latches into the transmitter's receptor. LED will blink when it is set correctly Attaching the terminal upside down will cause an error. After connection, make sure LED is blinking. CAUTION How to Apply to the Diaper Keep the sensor string from touching skin. Attach the sensor side of the pad to the diaper. 2. Wrap the diaper with its side cover and fasten with Velcro fastener. Fold back the transmitter on the cover. You can also secure the transmitter with a clip. If the string touches skin, the sensor may not work properly. Make sure the sensor is well adhered to the diaper. CAUTION 1. Attach the sensor pad to the diaper using double-faced tape. Attach the grey side of the pad to the diaper. Attaching the wrong side may cause an error. Change double-faced tape every day. Pre-used tape may cause an error. CAUTION CAUTION 3. Wrap with the center cover. Storage Caution When storing, detach the sensor pad from the transmitter, or remove batteries. Leaving the rear side of the sensor pad on a metal surface may cause malfunction. When not in use, make sure that the rear side of the pad does not contact a metal surface. CAUTION 1Specification Item Spec.
