Using Ac Power; Using Vehicle Battery Power - GRE PSR-282 Owner's Manual

Connect 4.7mm outer/1.7mm inner plug to the scanner's
PWR DC 9V jack.
Note: When you charge Ni-CD batteries, pay attention
not to over charge. Overcharging shortens battery life.
The scanner can also charge Ni-Cd batteries. 600mAh
batteries require 6 hours and 850 mAh batteries require
8 hours to charge.
Rechargeable batteries last longer and deliver more
power if you let them fully discharge once a month. To do
this, use the scanner until B appears. Then fully charge
the rechargeable batteries.

Using AC Power

You can power the scanner using a 9V, 300mA AC adapter
with 4.7mm outer/1.7mm inner plug.
Cautions:
• You must use an adapter that supplies 9V DC and de-
livers at least 300 mA. Its center tip must be set to
positive and its plug must fit the scanner's PWR DC
9V jack. Using an adapter that does not meet these
specifications 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 (4.7mm 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 4.7mm outer/1.7mm inner plug.
Caution: Always connect the DC adapter to the scanner
before you connect it to the power source. When you
finish, disconnect the adapter from the power source
before you disconnect it from the scanner.
To power the scanner using a DC adapter, set the
adapter's voltage switch to 9V. Next, insert the plug
(4.7mm outer/1.7mm inner plug) into the scanner's PWR
DC 9V jack. Plug the other end of the DC adapter into
your vehicle's cigarette-lighter socket.
