Telephone settings

Handset settings

When 

QUIET mode is turned on, the telephone silences all sounds during 

the set period of time (1-12 hours). However, the handset locator paging 
tone and any sound-generating operations initiated by users, such as making 
calls using the speakerphone or setting ringer volume, will sound as normal. 
After you turn on 

QUIET mode, this feature activates immediately and the 

answering system turns on automatically. When 

QUIET mode is on,  

the answering system takes calls and records messages without  
broadcasting them.

To turn QUIET mode on:
1. Press and hold 

QUIET # in idle mode to enter the QUIET mode setting 

screen. The screen shows 

Quiet:  _ _ hours [1-12].

2. Use the dialing keys to enter the desired number of hours (1-12) you 

would like to turn on 

QUIET mode, then press 

/SElECT. Your screen 

briefly shows 

Quiet mode on.

While 

QUIET mode is on, press and hold QUIET #. The screen then shows 

Quiet mode off briefly and then returns to idle.

If you change the base ringer, handset ringer, ringer volume, or key tone when 

QUIET mode is on, 

the sample plays but the feature is still muted after saving the setting.
After 

QUIET mode is turned off or the set period of time has expired, all muted features will be 

activated again.
When 

QUIET mode is on, the handset does not ring when there is an incoming intercom call, but 

the handset which initiates the intercom call does have the calling tone as normal.
