EPAS Preparation

Preparing the Electrical System

The EPAS utilizes a rechargeable lead-acid battery to power the
various components that make up the system. This battery maintains
a consistent charge for the components with internal batteries, as
well as, providing power to the components without batteries. Before
using the EPAS, it is important to fully charge the main system
battery.
Note: Even when the unit is turned off, small amounts of power
are required to retain memory contents in the Cassiopeia
PDA, which can cause the batteries to go dead even when
the unit is not in use.

Charging the Batteries

The batteries can be charged in two different ways: through an AC
power supply, or a 12 volt DC power supply from a car. The first
time you charge the EPAS, 24 hours is required to attain a com-
plete charge.

AC Charging of the Batteries

1.) Connect the DC connector of the AC adapter to the EPAS
external power port (see illustration on page 3).
2.) Plug the AC cord of the adapter into your AC power source.
3.) The LED marked "AC/DC Power/Charge" will light up to
indicate that the EPAS is connected to the AC power source.

DC Charging of the Batteries

1.) Connect the DC power cord to the EPAS external power port
(see illustration on page 3).
2.) Plug the other end into the car's cigarette lighter receptacle.
3.) The LED marked "Vehicle Power/Charge" will light up to indicate
that the EPAS is connected to a vehicle power source.
After the EPAS has charged for a full 24 hours, it is ready for use.

Low Battery Indication

The top LED installed in the case, marked "Low Battery", will light
up when it is time to recharge the EPAS. If you need to continue
testing after the "Low Battery" LED lights up, it is recommended that
you connect the EPAS to a dependable power supply, using either the
AC or DC power sources. After the initial 24 hour system charge,
a charge of 12 hours is recommended as a sufficient time period to
recharge the EPAS.
It is acceptable to leave the EPAS constantly connected to the AC
or DC power supply.
