Subsequent transmissions

Press and hold down button on any

optiPoint W1 professional using the same channel.

Since all phones on that channel are already in the receive state, there is no two-second delay.

The "start transmit" sound is played immediately.

Talk into the microphone.

Receiving transmissions

The phone plays the "receiving alert" sound and enters the receive state.

The phone will ignore the PTT button while in the receive state.

The screen shows the current active channel, the caller ID information of the current transmitter, and an indica- tion that the phone is receiving a broadcast transmis- sion. The caller ID is protocol specific. In most cases it is simply the extension number programmed in the phone from the on-hook user menu.

Change PTT volume

Set the volume for the active call.

A separate volume is maintained for PTT calls with the current volume selection retained in memory.

Muting a PTT call

Mute only affects the current call and the phone will play subsequent PTT calls.

Press soft key.

Confirm.

The prompt disappears after 3 seconds if the user doesn't confirm.

The Mute soft key turns into an Unmute soft key while in the mute state and can be used to unmute the PTT call (the confirmation prompt is displayed first).When the next PTT call period starts the audio is automatically unmuted.
