Powering Your Scanner
You can power your scanner with four AAfour AA
batteries (not supplied), or an external power, or an external power
source.
Batteries
When battery power is low, battery symbol
ashes and the scanner beeps every 30
seconds. When battery power is depleted, the
scanner turns itself off.
For the longest operation and best performance,
use alkaline batteries, available at your local
RadioShack store, or use RadioShack 1600
mAh nickel-metal hydride (Ni-MH) rechargeable
batteries.
Rechargeable batteries last longer and deliver
more power if you let them fully discharge
once a month. To do this, use the scanner until
battery symbol ashes.
Warning: Never install non-
rechargeable batteries in the
yellow rechargeable battery
holder. Non-rechargeable
batteries can get hot or
explode if you try to
recharge them.
To install batteries:
1. Slide open the battery compartment cover
on the back of the scanner.
2. Place 4 AA batteries into the correct battery
holder matching polarity symbols (+ / -):
• Black – Alkaline (non-rechargeable)
• Yellow – Rechargeable.
3. Place the battery holder into the battery
compartment and replace the cover.
To charge batteries:
1. Install rechargeable batteries.
2. Connect an external power source to the
PWR DC 9V jack. Using the scanner while
charging will increase charge time.
Battery Current Charge Time
Ni-MH 1600 mAh 16 hours
Ni-Cd 600 mAh 6 hours
Ni-Cd 850 mAh 8 hours
Do not overcharge batteries. Overcharging
shortens battery life.
• Each battery holder ts only one way. Do
not force it.
• Use only fresh batteries of the required size
and recommended type. Do not mix old
and new batteries, different types (alkaline
or rechargeable), or rechargeable batteries
of different capacities.
• Remove old or weak batteries. If you will
not use the scanner with batteries for a
month, remove the batteries. Batteries
can leak chemicals that destroy electronic
circuits.
• Always dispose of old batteries promptly
and properly. Do not bury or burn them.
