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.
