Description/Procedure
Battery Replacement The GTN has an internal keep-alive battery that will last about
10 years. The battery is used for GPS system information.
Regular planned replacement is not necessary. The GTN will
display a low battery' message when replacement is required.
Once the low battery message is displayed, the battery should
be replaced within 1 to 2 months. If the battery is not replaced
and becomes totally discharged, the GTN unit will remain fully
operational, but the GPS signal acquisition time may be
increased. There is no loss of function or accuracy of the GTN
unit with a dead battery. The battery must be replaced by the
Garmin factory repair station or factory authorized repair
station.
