Receiving Calls
When power is applied, the desk set is in the receive mode, allowing receive audio to be heard through
the speaker or handset. The desk set is always in receive mode unless the user presses the

buttons.
The desk set contains an internal or local speaker and a handset speaker, which operate as follows:
 When the handset is in the cradle or on-hook, receive audio is heard on the local internal speaker.
 When the handset is off-hook, receive audio is routed to the handset.
Handset Transmit
Using the handset is recommended when the desk set is located in noisy surroundings. Press the handset
PTT bar or

button and speak into the handset microphone.
Transmit From Internal Microphone
Use the internal microphone only in low noise environments. The handset must be on-hook for the
internal microphone to operate. Press the
TRANSMIT
button and speak in the direction of the internal
microphone. For the best transmit audio quality, maintain a distance of about 12 to 18 inches from the
microphone.
