Out of range indication
The cordless system uses special digital signal processing to ensure
maximum range for your call. If you go out of base range during a
conversation, the handset begins to give out an acoustic signal. To avoid
dropping your call, approach the base until the acoustic signal ends.
If you go out of range while in standby mode, the display will show
“Out of Range”.
Call duration time
The call duration time appears on the LCD after making or receiving a
call. This function starts 5 seconds after the beginning of a conversa-
tion and ends 3 seconds after the call is complete. The time is shown
in minutes and seconds (mm : ss).
