Radio Shack PRO-93 - Manual (Page 13)

13 Preparation
• Rechargeable batteries last longer and deliver more
power if you let them fully discharge once a month.
To do this, use the scanner until
(FNэ в8KK (FNэ в8KK (FNэ в8KK (FNэ в8KK
appears. Then fully charge the rechargeable batter-
ies.
Using AC Power
You can power the scanner using a 9V, 300 mA AC
adapter and a size C Adaptaplug (neither supplied).
Both are available at your local RadioShack store.
Cautions:
You must use a Class 2 power source that
supplies 9V DC and delivers 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 specifi-
cations 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,
disconnect the adapter from AC power before you
disconnect it from the scanner.
To connect the adapter.
1. Connect the Adaptaplug to the adapter's cord with
the tip set to positive.
2. Plug the adapter's barrel plug into the scanner's
PWR DC 9V jack.
3. Plug the adapter's two-prong plug into an AC outlet.
Using Vehicle Battery Power
You can power the scanner from a vehicle’s 12V power
source (such as cigarette-lighter socket) using a 9V, 300
mA DC adapter and a size C Adaptaplug™ adapter (nei-
ther supplied). Both are available at your local Ra-
dioShack store.
