NetLink e340/h340/i640 Wireless Telephones and Accessories User Guide

Initiating a call Press the Talk button and wait briefly to activate the channel before talking. You may begin talking when the display shows Transmitting.

Transmitting Once a call has been initiated, hold the handset two inches from your mouth and talk into the microphone. When the Talk button is released, the NetLink i640 Wireless Telephone then enters the waiting state where it monitors the channel for up to ten seconds.

Initiate subsequent transmissions by pressing the Talk button on any NetLink i640 Wireless Telephone using the same channel. The user can start talking immediately. The display screen shows the current active channel..

If no transmission occurs during the ten-second countdown period, the NetLink i640 Wireless Telephone reverts to the idle state.

Receiving Upon receiving a PTT transmission, the handset plays the “receiving alert” sound and enters the receive state.

In this state the handset receives all conversations on the selected channel. The handset will ignore the Talk button while in the receive state. The screen shows the current active channel, the caller ID information of the current transmitter, and an indication that the handset is receiving a broadcast transmission. The caller ID is protocol specific. In most cases it is simply the extension number programmed in the handset from the on-hook user menu.

At the end of a transmission, the handset enters the waiting state where it monitors the channel for up to ten seconds and displays “Waiting” on the screen. If no other transmission occurs within ten seconds the handset reverts to idle state.

Change PTT volume Use the Up and Down buttons to raise or lower PTT volume. A separate volume is maintained for PTT calls with the current volume selection retained in memory.

Muting a PTT call To mute a current call, press the Mute soft key. This brings up a Mute Two-Way Radio? prompt. Press the Yes or No soft key. The prompt disappears after three seconds if the user doesn’t confirm either Yes or No.

Mute only affects the current call and the handset will play subsequent PTT calls. Mute does not allow the user to use the handset’s keypad for anything else, including an OAI application.

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.

Early termination of a PTT call In order to terminate incoming broadcasts, press the Terminate soft key and answer Yes to the confirmation prompt. Push-to-talk audio is immediately stopped and the handset exits the PTT session. No other handset is affected. Only the current call is terminated for this handset. When the next PTT call period starts, the handset is again in the receive state. You may rejoin a still-active session by initiating a PTT call.

Users should disable the PTT feature in the on-hook user menu if it is desired to not receive any further PTT calls.
