VRC 89XX Radio Terminal Product Reference Guide for Embedded Windows
Use extreme care when routing and securing this cable from the terminal
to the vehicle power source. Hazards associated with improper wiring can
be severe. To avoid unintentional contact between the wire and any sharp
edges, use proper bushings and clamping where the cable passes through
openings. If the wire is subjected to sharp surfaces and excess engine vi-
bration, the wiring harness insulation can wear away, causing a short be-
tween the bare wire and chassis. This can start a fire.

Installation and the Internal Battery

The VRC89XX has an internal battery that preserves RAM if there is a temporary
interruption, disconnection or fluctuation in the main DC or AC power.
The internal battery may be depleted when you first install it. It charges itself from the
terminal's main power supply (DC or AC) when the terminal is running. It also charges when
the terminal is in suspend mode (by pressing the Suspend button), but will not charge if
power is removed from the terminal.
We recommend that you power on the terminal and allow the internal battery to charge for
a minimum of 24 hours before using the terminal. It takes 15 hours to fully charge the
internal battery. A fully charged internal battery can maintain data for up to 72 hours if the
unit is disconnected from its main power source.
