Remote control
When inserting or removing the batteries, push them towards
the battery terminal.
Installing the batteries incorrectly may cause the unit to mal-
function.
Precautions for battery use:
Insert the batteries according to the direction indicated 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 dam-
age 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 in-
terfere with operation. Change the lighting or the direction of
the unit.
Keep the remote control away from moisture, excessive heat,
shock, and vibrations.
