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.

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