Permanent ON/OFF function
Press button “ON/OFF” to select permanent ON or permanent OFF mode.
* Press button “AUTO”, “RESET” or “Ambient” to quit this mode.
The mode will change to AUTO Mode after power failure.
Sensor mode
Press “Auto Mode” button, the sensor starts to function and all settings remain the same as the latest status before the light is switched on/off.
This button is disabled.
SEMI-AUTO mode
Press button “Ambient”, the surrounding lux level is sampled and set as the new daylight threshold.

Hold-time
Press buttons in zone “hold-time” to set the hold-time at 5sec / 1min / 5min / 10min / 15min / 30min / 60min.
Press buttons in zone “ Daylight threshold” to set daylight sensor at 2Lux/ 10Lux / 50Lux / 100Lux / 300Lux / 500Lux / Disable.

2.2 Intelligent Photocell (daylight detection prior to motion detection)
The built-in photocell will also automatically turn off the light when the ambient natural light exceeds the
programmed lux level for more than 5min, regardless of whether motion is detected or not.
2.1 On/ Off Control
This sensor is a motion switch, which turns on the light upon detection of motion, and turns off after
a pre-selected hold-time when there is no movement. A daylight sensor is also built in to prevent the light
from switching on when there is sufficient natural light.
