Important Operating Instructions
• To prevent condensation when a vehicle-mount is moved from a freezer to a
warmer environment, it is recommended that the computer power be left on
for at least five minutes.
• When not in use, vehicle-mount freezer units should be stored in tempera-
tures above 0° C (32° F).
• To prevent keyboard keys from freezing up, the keyboard should be
mounted off the horizontal plane. This allows water to run off the keyboard
and prevents it from pooling on the keypad, freezing and finally physically
jamming the keys. Mounting the keyboard off the horizontal plane also pre-
vents water from dripping onto the keypad area.
Backup Battery
The vehicle-mount back up battery capacity is reduced as the operating temperature
cools. The table below provides a general outline of battery capacity based on the
operating temperature. Charging of the back up battery will occur between +5° C
and +45° C.
Note: If the backup battery temperature is less than +10° C and a brown-out
occurs, the display backlight will switch off in order to maintain vehicle-
mount operations. The backlight will switch back on when external power
is restored or the battery temperature is above +10° C.

Warning: Do not install the 8525 G2/8530 G2 in such a way that the power
cable is bent 90 degrees as this may damage the power cable and
power cable strain relief.
