15 Battery
15.1 Overview
The monitor is designed to operate from battery power when AC power supply is not
available. In case of power failure, the equipment will automatically run power from
internal battery. So we recommend you always install a fully charged battery in the
equipment.
Where the integrity of the external protective conductor in the installation or its
arrangement is in doubt, the equipment shall be operated from the battery.
CAUTION
Remove the battery before transporting the equipment or if the equipment will
not be used for a long time.
NOTE
It is recommended to always install a fully charged battery in the monitor to
ensure normal monitoring in case of accidental power failure.
The on-screen battery symbol indicate the battery status as follows:
Indicates that battery works correctly. The solid portion represents the
current charge level of the battery in proportion to its maximum charge level.
Indicates that the battery has low charge level and needs to be charged.
Indicates that the battery is almost depleted and need to be charged
immediately. Otherwise, the monitor will shut down automatically.
Indicates that no battery is installed.
The capacity of the battery is limited. When the battery is low, the technical alarm area
displays [Low Battery], the alarm lamp flashes, and monitor produces alarm sound.
If the battery is deplete, the battery symbol on the screen starts to flash, the technical
alarm area displays [Battery Depleted], the alarm lamp flashes, and monitor produces
alarm sound. At this moment, connect the equipment to AC mains to run the equipment
and charge the battery. Otherwise the equipment will shut down.
