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 4½ 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
Remote
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 turned OFF.
• 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 into the
Scanner, it indicates that the battery pack is on maintenance
(“trickle”) charge.
• The average time to recharge the battery pack is about 4½ hours.
• To maximize battery pack life, avoid extreme temperatures.
• Using OMNIScanner with the backlight turned ON causes increased
battery drain.
(See Chapter 1 - Introduction: OMNIScanners Keypad:
Backlight)
• Average daily life of the battery pack is about ten hours.
• An external charger is also available. Contact your Microtest distributor
for details on the external charger, Microtest Part Number 8003-01.
