Chapter 13 Battery
13.1 Overview
The monitor has built-in chargeable battery, when the monitor is disconnected from the external AC power supply, then
it turns to be powered by built-in battery. When the monitor is supplied by external AC power, then the battery will be
charged. Generally, it’s unnecessary to maintain the battery when using under normal working condition.
When the monitor is powered by built-in battery, and battery is in low voltage, then technical alarm will be triggered, and
message “Low battery” pops up. At this moment, the user should connect the external power immediately to make sure
the monitor continue working.
The capacity of the internal battery is limited. If the battery charge is too low, a technical alarm will be triggered and
the message displayed. At this moment, apply AC/DC power to the monitor. Otherwise, the monitor will power off
automatically before the battery is completely depleted.

In order to maintain battery supply time and prolong battery lifetime, please charge the battery every one or two
months if don’t use battery for a long time. Charge battery at least 12-15 hours every time. Before charging, run
down the internal battery until the monitor turn off automatically to minimize memory effects. Charging time

off automatically when the battery is depleted..
