When inserting or removing the batteries, push

Installing the batteries incorrectly may cause the
unit to malfunction.
Precautions for battery use:
Insert the batteries according to the direction in-
dicated in the battery compartment.
Replace all old batteries with new ones at the
same time.
Do not mix old and new batteries.
Remove the batteries if they are weak or if the
unit will not be used for long periods of time.
This will prevent potential damage due to battery
leakage.
Caution:
Do not use rechargeable batteries (nickel-cadmium
battery, etc.).
Notes concerning use:
Replace the batteries if the operating distance is
reduced or if the operation becomes erratic.
Periodically clean the transmitter LED on the
remote control and the sensor on the main unit
with a soft cloth.
Exposing the sensor on the main unit to strong
light may interfere with operation. Change the
lighting or the direction of the unit.
Keep the remote control away from moisture,
excessive heat, shock, and vibrations.
