Using In-call Features
Handsfree Speakerphone
The speakerphone feature allows you to 
hold impromptu meetings in Phone, PABX, 
and full-duplex Private Calls.
During speakerphone operation, you may 
either speak or listen, but you cannot do 
both at the same time.
1. To activate speakerphone, press Spkr. The display shows 
Speaker ON.
2. Place the  MTH800 30 to 60 cm away from you. In a noisy envi-

better transmission.
3. To de-activate speakerphone, press Erpce. The display shows 
Speaker OFF.
To burst into conversation while the other party is talking, 
press and hold PTT. You will hear a tone. Start talking, and 
release PTT to listen again to the other party.
