Section F - Care of the GPS Receiver
Very little effort is required to care for the
Apollo handheld GPS receiver. Its rugged
construction and quality design will yield
years of trouble-free use.
Treat the receiver as you would any piece of
electronic equipment. Avoid exposing the
receiver
to temperature extremes. High
temperatures can damage internal
components. Do not store or operate the
receiver
in below freezing temperatures.
Although the receiver is housed in a water
resistant case, avoid submersing the unit in
water. Also avoid subjecting the receiver to
severe shock, as internal damage could occur.
Replacing
the
Batteries When not connected to an external power
source, the receiver is powered by six AA
batteries. Replace the batteries by removing
the battery compartment cover located on the
rear side of the receiver. Observe polarity
markings
inside the compartment when
replacing batteries.
Avoid leaving weak or discharged batteries
installed in the receiver as leakage could
damage internal components.
