Making calls (continued)
If the battery becomes weak during a call
The handset will beep every three seconds five times and E and
“BATTERY LOW” appears on the display. Finish your call and charge
the battery pack.
For optimum performance, charge the battery for a full 12 hours.

inactive, i.e., unable to make or receive a call.

you fully charge the battery before the next usage.

procedure.
1
Press (HOLD) on the handset.
