EPLACING THE ATTERY
When removed from a vehicle, the DriveRight unit taps its own
battery for power (instead of relying on the vehicle's battery). On
the unit's battery alone, a unit will operate for 260 hours or, in
sleep mode, 2 months.
The life of the unit's battery depends on your download sched-
ule. For example, if you take the unit out of the vehicle 5 days a
week, 8 hours a day, the unit's battery can last up to 9 months. In
that situation, because not all out-of-vehicle time will be spent in
sleep mode and because of the occasional delay in returning the
unit to the vehicle, we recommend replacing the battery every
6 months. If at any time the LCD display begins dimming, the
battery is low and due for replacement.
If you plan to store a unit out-of-vehicle for more than a week,
we recommend removing the battery. When you replace the bat-
tery, data and settings are not lost (though you will need to reset
the date and time).
