1.3.1 Power

A 12 V/ 1000 mA wall adaptor is used to power the 5000/5100 terminals. Furthermore,
an optional 7.4 V/ 2000 mAh Li-ion battery pack provides more than six extra hours of
uninterrupted operations when the line power is down. Such power switching
mechanism is actuated by a power switch, which seamlessly switches between the
line power and the battery pack without any user's intervention.
When the line power is resumed and the battery pack has been used up, an on-board
battery charging controller fully charges the battery pack within twenty hours. This
controller chip helps to assure fast and safe charge by monitoring/controlling the
battery voltage, temperature, charging current and so on. It also includes a
mechanism to provide protection from over charging.
When a power outage occurs, the main battery is to maintain operation for more than six
hours.
In addition, one 3.0 V/7 mAh rechargeable Lithium button cell on the main board
retains data in SRAM and maintains the running of the real-time clock and calendar. It
takes at least twenty-four hours to fully charge the backup battery.
For a fully charged backup battery, it can last for at least one week.
