• To prevent damage to Ni-Cd and Ni-MH
batteries, never charge them in an area where
the temperature is above 113°F (40°C) or below
40°F (4°C).
• If you connect an external power source to the
scanner with ALKALINE/RECHARGEABLE set to
ALKALINE, CHArg appears but the scanner
does NOT charge the batteries. The scanner's
microprocessor unit does not recognize the
switch position when you incorrectly connect an
external power source. Make sure that you use
the correct batteries and set ALKALINE/
RECHARGEABLE to the correct position when
you connect an external power source.
• If CHArg does not appear, the rechargeable
batteries might be completely discharged.
Connect the scanner to an AC or DC adapter and
wait about 1 minute. Then, unplug the adapter
from the scanner for a few seconds then plug it
back in.
