Charging the battery via a USB port
► Connect the ActiveSync cable to your Pharos Traveler GPS 535.
► Connect the ActiveSync cable to the computer’s USB port.
i
The computer’s USB port must deliver no less than 500 Ma of power. Because of the low
charging current, the charging process will take longer than it does using the power
adapter.
Optimizing battery operating time
When you have completely charged the battery, you can operate the Pharos Traveler GPS 535 for
up to 12 hours without a power connection. However, it is not possible to exactly specify the
maximum operating time, as different applications use more or less energy.
In the system settings you can make settings that help you save energy when using your Pharos
Traveler GPS 535. These settings enable you to use the battery operating time optimally.
i
In the default setting, a setting is activated that automatically switches the Pharos Traveler
GPS 535 into the Suspend mode after three minutes when working without a power
connection if no entries are made during this time. You can switch on the Pharos Traveler
GPS 535 again at any time by briefly pressing the Suspend/Resume button and then
continue working where you left off.
