❏ If you go more than 5 minutes without press-
ing a button, the unit enters “sleep mode.”
In sleep mode, all but the most essential unit
functions (that is, time and date) shut down.
The display goes blank and no data is recorded
when the unit is “asleep.”
NOTE: The unit never goes into sleep mode when
connected to your vehicle (i.e., receiving
power from your vehicle’s battery).
To “wake up” the unit, press MODE or recon-
nect the unit to your vehicle so it receives
power from your vehicle’s battery.
❏ The unit cannot record data.
This means the unit is in “sleep mode”
because it is not connected to the vehicle and
does not receive power from the vechicle’s bat-
tery. Thus if you do not power the Trip 500AL
from your vehicle’s battery, it will not record
any data.
❏ The display lamp is disabled.
You cannot turn on the unit’s display lamp.
❏ The unit’s beeps are extremely faint.
The beeps following actions are extremely
quiet to conserve power.
Replacing the Battery
When removed from a vehicle, the DriveRight unit taps into its
own battery for power (instead of relying on the vehicle’s bat-
tery). On the unit’s battery alone, a unit will operate for 260
hours or, in sleep mode for 4 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 16 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 year. 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 but you will need to reset the
date and time.
