Charging the Scanner Battery
Fully charge the scanner battery before using the scanner for the first time. To charge the scanner battery, place the scanner in the
cradle, ensuring that the metal contacts on the bottom of the scanner touch the contacts on the cradle. The battery begins charging
when the scanner LED indicator starts flashing green. A complete charge of a fully discharged battery can take up to three hours using
external power and up to five hours using non-external cable power.
To avoid a battery temperature fault, always charge the battery in the scanner within the recommended
temperature of 32° to 104° F (0° to 40° C) nominal, 41° to 95° F (5° to 35° C) ideal.
Charging LED
When powered up, the cradle LED is always green. The scanner LED flashes a green during charging. See Table 2-2 on page 2-4 for
all charging LED indications.
Reconditioning the Scanner Battery
To maintain optimal performance of the scanner NiMH battery, perform a battery recondition approximately once a year.
To begin the battery recondition cycle:
1. Scan Battery Recondition below.
Battery Recondition
2. Place the scanner into the cradle.
3. The scanner must perform two charge cycles to complete the battery reconditioning process (discharge/charge/discharge/
charge). See Table 1-1.
If the scanner is removed from the cradle during the battery reconditioning cycle, the scanner exits the battery
reconditioning mode of operation and returns to the normal mode of battery charging (see Charging the
Scanner Battery). To restart the battery reconditioning cycle, re-scan the Battery Recondition parameter and
place the scanner in the cradle.
