The sensor range is the range an object can be away from the sensor in order to activate the faucet.
The sensor is factory preset. If necessary, it can be adjusted as follows:
a. Adjusting the senor range without remote control
1 – Disconnect the power supply, battery or transformer, from the
sensor.
2 – Make a short circuit between the (+) and the (-) of the sensor.
You can use a screw driver or another conductor material to make this
short circuit. Alternatively, after disconnecting the power supply,
activate the sensor three or four times. Do not make a short circuit on
the power supply or on the sensor when the power supply is connected
to the sensor.
3 – Reconnect the power supply to the sensor.
4 – To enter into the adjusting mode, put your hand in front of the
sensor at a distance of 2" (5cm) to 4" (10 cm) within 5 seconds after the
reconnection of power supply.
Note: If you will not put your hand in front of the sensor
after connecting the power supply, the sensor will not
enter into adjusting mode and the previous setting will
return.
5 – When the sensor enters into adjusting mode and your hand is in
front of the sensor, a slow flashing of the red light at the front of
sensor
will occur.
6 – Keep your hand in front of the sensor until the slow flashing
changes into quick flashing. At this point move your hand to required
distance from the sensor and wait until the red light will stop flashing,
7 – When the red light has turned off, your sensor has been adjusted to
the required distance.
8 – Check the distance you have set and if it is not satisfactory, repeat
steps 1-6.
