Remove the screw from the battery compartment cover. (Fig.1) 2. Install an alkaline 9V battery, now unit enter into standby mode. 3. Replace the battery cover and screw. 4. Learning ID code to main unit. 5. Mount the main unit at the desired location with anchors and screw (included). 6. Press suctorial cap against of water detect sensor on the desired location. (Fig.2) NOTE: 1. The wireless water overflow sensor output RF signal compatible trigger T015S, T016S, T018S, T068S auto dialer function, must learn ID code to main unit then use, learn ID operation see main unit manual. Fig.1 Fig.2 FEATURES 2. After select a location, you should test the sensor transmitting range before mount it permanently, turn local alarm switch to OFF, turn the CHIME switch to ON of T015S, T016S main unit or press HOME button of T018S, T068S, after 60 seconds, put sensor into water to trigger, you will hear the main unit sounds “DING DONG” chime if signal is received successfully, if not , change location is required. OPERATION After 60 seconds install 9V battery, the unit will into standby mode, once water overflow sensor detect location will output wireless radio signal to trigger auto dialer and LED flash, then sound alarm 45 seconds, you can turn switch select alarm sound on or off. BATTERY LOW INDICATOR When 9V battery goes lower, the LED will light on 3 seconds and off 1 second, change a new alkaline 9V battery immediately, to avoid the sensor might not detection properly. Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance will void the user's authority to operate the equipment. Any change to the equipment will void FCC grant. This equipment has been tested and found to comply with the limits for a Class C digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation INSTALLATION size:90X175mm p/n:610-66000-00XR white paper print black words 610-66000-001R -1- -2-
