Operating On Battery Power After Power Loss - Motorola MT7711 User Manual

Operating on Battery Power after Power Loss

When an optional Motorola-supplied or a separately purchased MTRLC LLC
(part number 98250) battery is installed, your MT7711 will automatically fail
over to battery power if there is a power outage at your location. The battery
will support standby operation for Tel1 for up to eight hours, and talk time
of up to five hours. Note that attached phones such as cordless phones that
require their own power will require their own backup power source.
Standard corded handsets do not require their own backup power source.
When running under battery backup power, only the Tel1 and Battery lights
remain lit. The battery light behaves according to this table:

During battery backup, the Battery light will remain ON until it is almost
depleted. Then it will go into a Fast Blinking mode until it is exhausted.
The Battery Purchase or Replacement section on page 19 describes how
you can make sure you have phone service even if your MT7711 loses
power.
