Panasonic KXTG4753 - Manual (Page 28)

*7 Turn this feature off if you prefer not to hear key tones while you are dialing or pressing any
keys, including confirmation tones and error tones.
*8 If you subscribe to a Caller ID service and want to view the caller’s information after lifting up
the handset to answer a call, turn off this feature.
*9 The flash time depends on your telephone exchange or host PBX. Contact your PBX
supplier if necessary. The setting should stay at “700 ms” unless pressing MFLASHN fails to
pick up the waiting call.
*10 Generally, the line mode setting should not be changed. This setting automatically maintains
receiver volume at the proper level depending on the current telephone line condition. Set
the line mode to “A” if telephone line condition is not good.
