Insert 3 AA-size 1.5V alkaline batteries to the battery compartment, ensuring 
correct polarity is put.

MODE 1 is showing as main display on the screen.    Once mode setting is finished 
(MODE 2 to MODE 6), the screen will return to main display automatically after 12 
seconds, or by pressing

1. Illumination

 

 
1.1 Display of Current Illumination 

 
After power-up (batteries are inserted), the LCD screen displays the current 

illumination.  All icons are displayed with LCD backlight illuminates 3 seconds. 
Press any key will beep once and extend the backlight for another 12 seconds. 
The illumination 

detecting range

 is from 

0

 to 

3000

 LUX.  When illumination 

reaches the limit (3000 LUX), 

MAX

 icon will be displayed on the screen. 

 
The detecting function is disabled while you are operating the sensor.    Wait for 12 
seconds to enable trigger-ON or trigger-OFF function.  If trigger-ON or trigger-OFF 
value has already been set, detecting function will be enabled 10 seconds after 
sensor is re-powered. 
     

1.2 Lux Trigger-ON 

 
Press 

 and select MODE 2 to enter setting of lux trigger-ON. Icon 

 

flashes and the screen shows the recorded trigger-ON lux. If no value is preset, the 

screen will display “ 

- - - 

LUX

”. 

 
To adjust trigger-ON value, press and hold 

  for 5 seconds until a long beep is 

sounded. The  “

- - -

” starts flashing. Use 

 

and 

  button to adjust the lux value, 

and hold 

 or 

  button to scan through the lux reading from 30 to 1000 (the lux 

value can only be adjusted on the basis of 10 LUX per unit; the default value is 300 
LUX). Once the value is selected, press 

  to confirm setting or press 

ESC/

 

to cancel. 
 
To clear the trigger-ON record, press both 

 and 

 at the same time.  The 

record is cleared after a long beep is sounded. 
 
If lux of ambient light is lower than the preset trigger-ON value, Illumination Sensor 
will emit RF signal to the nodes of Grouping 2.    The screen of sensor will return to 
MODE 1 and the icon 

  is flashing with backlight illuminates and 4 continuous 

beeps sound for 1 second.    Press any key to stop the beep tone. 
 
To avoid the problem of consecutive triggering, once Illumination Sensor has been 
triggered, it has to be placed still for 2 minutes (restriction) before lux trigger-ON is 
enabled again.  To clear this restriction, the detected lux value of ambient light 
during this two-minute period MUST be higher than the preset trigger-ON value, 
otherwise the sensor will keep recounting 2 minutes before it can be triggered again
