until it beeps every 15 seconds and   
flashes.
• 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. This is because 
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.
