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.
