Notes on using the remote control unit
•Point the top of the remote control unit toward the REMOTE SENSOR section as directly as possible. The distance operable from the main unit decreases if you point the remote control unit at an angle.
•Do not expose the REMOTE SENSOR section to strong lighting or direct sunlight.
•Make sure that there are no obstacles between the remote control unit and the REMOTE SENSOR section.
3Replace the cover.
Battery replacement
The maximum operating distance between the remote control unit and the REMOTE SENSOR section on the main unit is approximately 7 meters.
When this operating range decreases or operations with the remote control unit become unstable, replace both batteries with new ones.
