Notes on battery use
To avoid damage from battery leakage and
corrosion:
Make sure the polarity of the batteries
match the + and – markings in the
battery compartment.
Do not use an old battery with a new
one, or different types of batteries
together.
Remove the batteries when the system
will not be used for a long period of
time.
Do not charge the batteries.
If any battery leakage occurs, replace both
batteries after cleaning the battery
compartment.
Notes on the wireless remote
•To prevent deformation due to heat, do not
leave the remote in a place subject to direct
sunlight.
•Direct sunlight may affect the system’s
ability to receive infrared signals from the
remote. If this happens, move the remote
closer to the remote control sensor of the
system.
•When parking your car, put the remote
somewhere, such as the glove compartment,
that is away from direct sunlight to prevent
deformation due to heat.
About the LCD display on the
display section
When the temperature is extremely high or
low, the display may become dim and hard to
see. This is due to the characteristics of the
LCD and is not a malfunction. The display
will return to normal when the temperature
becomes normal.
Wireless Remote
Installing batteries in the wireless
remote
Insert two size-AA (R6) batteries with the
correct polarity.
Battery life
When the batteries become weak, you will
not be able to operate the unit with the
wireless remote. Battery life is about six
months (or shorter, depending on the way the
remote is used). If the remote becomes
inoperative, replace the batteries, then verify
that it can operate the system.
