Realistic PRO-50 - Using an Optional Adapter; Important Information About the External Power Jacks; Using an AC Power Source

USING AN OPTIONAL ADAPTER
IMPORTANT INFORMATION ABOUT
THE EXTERNAL POWER JACKS
The scanner has two external power jacks— P WR and CHG.
It is important that you understand the purpose of each jack
before you connect any adapter to the scanner.
The PWR jack powers the scanner and disconnects the in¬
ternal batteries. You can use this jack with an external power
source (AC or DC adapter) regardless of the type of batter¬
ies you install.
The CHG jack supplies power to operate the scanner and
also charges the internal batteries. Use the CHG jack only
when you install rechargeable nickel-cadmium batteries.
Warning: Never use the CHG jack with non-rechargeable
batteries! If you try to recharge non-rechargeable batteries,
they become very hot and could explode.
USING AN AC POWER SOURCE
You must use an adapter that supplies 9 volts DC power and
delivers at least 300 milliamps. Its center tip must be set to
negative, and it must have a plug that properly fits the scan¬
ner’s PWR jack. Using an adapter that does not meet these
specifications could damage the scanner or the adapter.
Consult with your local Radio Shack/Tandy store for a suit¬
able adapter.
Plug the adapter’s barrel plug into the scanner’s PWR jack.
Then plug the adapter’s power module into a standard AC
outlet.
When you finish using the AC adapter, disconnect it from the
AC outlet first. Then disconnect it from the PWR jack.
Note: If you have installed rechargeable nickel-cadmium
batteries in the scanner, you can connect the AC adapter to
the CHG jack. This powers the scanner and recharges the
batteries at the same time. See “Charging Nickel-Cadmium
Batteries.”
