and OMNI

Remote

use a charging mechanism that minimizes

the effects of shallow discharging. To maximize battery life, the battery

temperature is monitored and maintained within limits during the charging

process. Charging under high temperature conditions may result in longer

recharge times or premature termination of charging.

Battery Charging

Charging of the battery is enabled in the OMNI

Scanner

and OMNI

Remote

whenever the AC adapter is plugged in and the units are powered off.

The recharge time is typically 3 hours to completely charge a fully dis-

charged battery.

Charging is automatically terminated by the units when full capacity or over

temperature conditions are reached. To enhance long term life and capac-

ity of the battery a maintenance and topping charge period starts right after

the rapid charge is completed. The charging status is displayed on both

units. The graphic LCD displays charging status on the OMNI

Scanner

while LEDs indicate the status on the OMNI

Remote

unit.

Status conditions are as follows:

· Charge (RED) for OMNI

Remote

low battery status

· Charge (GREEN) while OMNI

battery is charging

· Charge (GREEN - blinking) when battery is charged

Battery Tips

· Power off the unit before changing the battery pack. Charging is only

enabled when the unit is off or operate unit from AC.

· If not on AC power, the battery packs must be replaced within five

minutes to avoid loss of time and date in the OMNIScanner unit.

· If the display goes blank while the AC adapter is plugged in to the

Scanner, it indicates that the battery pack is on maintenance

(“trickle”) charge.

· The average time to recharge the battery pack is about 3 hours.

· To maximize battery pack life, avoid extreme temperatures.

· Backlighting the display causes increased battery drain.

· Average daily life of the battery pack is about ten hours.
