APPENDIX
Battery Information
Your unit contains an internal (non-
removable) lithium-ion battery. The
battery should last up to 8 hours,
depending on usage.
The battery icon in the corner of
the Menu page indicates the status of the
internal battery. If the icon is not present,
the c550 is connected to external power.
Contact your local waste disposal
department for information on properly
disposing of the unit.
Maximizing the Battery Life
• Turn off GPS ( > System
> GPS Mode > GPS Off) when you
do not need to receive GPS signals,
or use Normal mode when you do
not need to use WAAS or EGNOS.
• Turn the backlight brightness down
(on the Menu page, touch ).
• Do not leave your c550 in direct
sunlight. Avoid prolonged exposure
to excessive heat.
About Satellite Signals
Your c550 must acquire satellite signals
to operate. If you are indoors, near tall
buildings or trees, or in a parking garage,
the c550 cannot acquire satellites.
Go outside to an area free from tall
obstructions to use your c550.
When the c550 has acquired satellite
signals, the signal strength bars on the
Menu page are green . When it
loses satellite signals, the bars turn red or
disappear .
