Battery Life and Maintenance

Battery Life and Maintenance
The monitor was shipped from the factory with a fully charged battery. Since the monitor draws
some battery power even while turned off, it is recommended that the monitor be operated on
line power for the first 24 hours to allow ample time for the battery to fully recharge.
The monitor may be operated on line power while the battery is recharging. Approximately 16
hours are required to fully recharge a discharged battery.
During prolonged periods of storage or shipment, the battery may discharge enough to prevent
the unit from turning on while operated from battery power. If this occurs, plug in the line cord,
set the switch on the rear panel to the "|" On position, ensure that the green
front panel is illuminated, and allow the monitor to charge for 24 hours before switching it on.

Mains Voltage Configuration

The rear panel power entry module indicates the mains voltage setting for the monitor. Check
that the voltage is correct before attaching the AC line cord and powering the monitor. The
Model 2001 can be set to operate from 100-120 VAC 50/60Hz or 200-240VAC 50/60Hz.
Instructions for fuse replacement and changing the mains voltage setting follow.
CAUTION:
(see table below)

Fuse Replacement

1. Check that the monitor is OFF.
2. Set the rear panel power entry module switch to OFF ("O"). Remove the AC line cord from the
power entry module.
3. Using a flat blade screwdriver, pry the fuse access door open to expose the fuse housing. Note
the orientation of the fuse housing (this determines the mains operating voltage).
