TROUBLESHOOTING
Lights do not turn on with motion (LED does flash):
1. Press and release each button to make sure that the correct lights come
on for each relay. If the lights turn on with the button press, verify that the
correct On Mode is selected in DIP switches 5 and 6.
2. Check to see if light level control is enabled: cover the sensor lens with
your hand. If the lights come on, adjust the light level setting.
3. Check all wire connections, in particular, the Load connection.
4. If lights still do not turn on, call 800.223.4185 for technical support.

ADJUSTMENTS
Sensor Adjustment
The OSR300S is preset to SmartSet mode. It is designed for “Install and Forget”
functionality. If you need to change the settings, follow the directions below.
All major adjustments to the OSR300S must be made with the wall plate
removed. To access the DIP switches, remove the button cap by squeezing the
top sides of the button assembly and pull it gently away from the unit.
When the adjustments are completed, replace the button cap by inserting
its hinges into the LED light bar and then squeeze the top of the button while
pressing it into the unit. Reinstall the cover plate.
Light Level Adjustment
The light level setting only affects the secondary relay. The light level can be
set with the overhead lights on or off. To enable light level control and set the
threshold to match the current ambient light level, press and hold the Relay 2
button for 3 seconds, until you hear a beep. Step away from the sensor. After
25 seconds another short beep sounds, indicating that the threshold level is
set. This threshold is retained, even if power is lost, until it is disabled then
re-programmed in this manner. To disable light level control, press and hold
the Relay 2 button for ten seconds, until a beep tone sounds.
Reset to Default
Press and hold the Relay 1 button for ten seconds to reset the OSR300S to
factory settings. This resets the sensor occupancy history and disables light
level control (the brightest ambient light will not hold the light off).
