Using Ac Power; Using Vehicle Battery Power - GRE PSR-295 Owner's Manual

To charge batteries with a DC adapter from a DC power
source, you must use a 9V, 300mA DC adapter with
4.75mm outer/1.7mm inner plug.
It takes about 16 hours to recharge fully discharged
1600mAh Ni-MH rechargeable batteries. You can oper-
ate the scanner while recharging the rechargeable bat-
teries, but charging takes longer.
Notes:
• The scanner can also charge Ni-Cd batteries. 600mAh
batteries require 6 hours and 850mAh batteries require
8 hours to charge.
• When you charge Ni-Cd batteries, do not overcharge
them. Overcharging shortens battery life.
• Rechargeable batteries last longer and deliver more
power if you let them fully discharge once a month. To
do this, use the scanner until Low battery! appears.
Then fully charge the rechargeable batteries.

Using AC Power

You can power the scanner using a 9V, 300mA AC adapter
with 4.75mm outer/1.7mm inner plug.
CAUTIONS:
• You must use an adapter that supplies 9V DC and de-
livers at least 300mA. Its center tip must be set to posi-
tive and its plug must fit the scanner's PWR DC 9V
jack. Using an adapter that does not meet these speci-
fications could damage the scanner or the adapter.
• Always connect the AC adapter to the scanner before
you connect it to AC power. When you finish, discon-
nect the adapter from AC power before you discon-
nect it from the scanner.
To power the scanner using an AC adapter, insert the
plug (4.75mm outer/1.7mm inner plug) into the scanner's
PWR DC 9V jack. Then connect the other end of the
adapter to a standard AC outlet.

Using Vehicle Battery Power

You can also power the scanner from a vehicle's 12V
power source (such as a cigarette-lighter socket) using a
9V, 300mA adapter with 4.75mm outer/1.7mm inner plug.
