OWNER’S MANUAL  
 
For safety, install the set in a position at which the driver cannot see it.  
Do not disassemble or modify the set. Doing so may damage it and voids  
your warranty.  
Keep drinks and drops from umbrellas away from the set. Water may dam-  
age the internal circuitry.  
Do not let the set become hot. If temperature in the car is high or the set  
has been exposed to direct sunlight and is hot, lower the temperature before  
using it. (The liquid crystal panel will work properly within a temperature  
range of 30 – 113 degrees F.)  
In extremely cold temperatures, the movement of the picture may be slow  
and the picture may be dark, but this is not a malfunction. The set will work  
normally once the temperature increases.  
Small black and shiny dots inside the liquid crystal panel are normal for liq-  
uid crystal products.

or cause the paint to peel. Also leaving rubber or plastic products in contact  
with the cabinet for long periods of time may cause stains.

The LCD panel tends to collect dust, so wipe it off occasionally with a soft  
and dry cloth.  
The surface is easily scratched; do not rub it with hard objects.
