Off-Hook Monitoring lets you put a call on speaker while the handset is off-hook. 
You can still communicate with the outside party via the handset, but you will also 
be able to hear him on the phone’s speaker. He will only be able to hear what is 
spoken through your handset, however - audio will not be transmitted through your 
microphone.

1.

During a handset call, press the ON/OFF key.

• Another receiver path is established on the phone’s speaker -- you 

can now hear the outside party on the speaker as well as in the 
handset.

• Your phone’s microphone is muted so that the outside party hears 

only what is spoken through your handset. (To mute handset 
transmission, press MUTE.)

2.

To disable Off-Hook Monitor (“kill” the speaker but stay on the line 
with the outside party through the handset), press ON/OFF again.

You can now establish separate speaker volumes internal (intercom) and external 
(CO) calls.

To adjust volume levels, press the VOLUME key (

s

 or 

t

) during the appropriate call 

state. 

Adjusting speaker volume will affect only the speaker (i.e., not the handset), and 
vice-versa.
