8.5 When “BATTERY ALARM!”
Appears
A lithium battery (type: TZ6580553A, code
no.: 000-139-051) is installed on the circuit
board inside the display unit and it preserves
data when the power is turned off. The life
of the battery is about three years. When the
battery voltage is low “BATTERY
ALARM!” appears on the display to alert
you. When this happens, contact your dealer
to request replacement of the battery.
8.6 Clearing Data
You may clear GPS data and menu settings
individually or collectively, to start afresh
with default settings or, in some cases, re-
