Temporary ring silencing
Press 
OFF/CLEAR or MUTE/DELETE while the telephone is ringing to silence the ringer tempo- rarily. This will silence the ringer without discon- necting the call. The next incoming call will ring normally at the preset volume.
NOTE: If there is more than one handset in use, all hand- sets ring with an incoming call except those with the vol- ume turned off. Press 
OFF/CLEAR or MUTE/DELETE on one handset will only silence the ringer of that particular handset but the other handset(s) will continue to ring.
