Battery Maintenance

Maintaining the Monitor  

You can determine the monitor’s battery strength by the color of the battery icon, or by the 
number of illuminated bars on the battery icon. The following table describes the battery icon 
behavior:

•

If the battery operating time is less than 30 minutes, the battery icon flashes. A low 
priority audio alarm sounds (1 beep every 4 seconds).

•

When the battery is empty, a "Low Battery" INOP message displays in the Message 
frame and the audible alarm sounds. Pressing any front panel button clears the INOP 
and silences the audible alarm. The battery icon continues to flash until the monitor is 
powered down or automatically switches off.

If the new battery is partly or fully charged, the monitor starts operating.

A complete battery recharge (>90%) requires 8 hours in standby mode or 14 hours in 
operational mode.
