ALL-IN-ONE HEADSET OPERATION
The Headset control buttons will activate when pressed lightly.
Use your fingertips, not your fingernails, to press the buttons.
Power On/Off
• Power On — Press and release the power button on the inside
of the Headset housing. A voice message in the earpiece will say
“Power on, Headset #, Version #” and the power light will go on.
The STATUS indicator on the Base Station will momentarily indicate
the Headset ID number.
• Power Off — Press and hold the power button for approximately
3 seconds. A voice message in the earpiece will say “Power off,”
and the power light will go off.
ISO and IC
The ISO, IC1 or IC2 buttons can be used to talk to other COMMUNICATOR
®
s.
IC will send the audio signal out to intercoms through the HEADSET and
4-WIRE connections on the rear panel of the Base Station.
Depending on your Base Station RELAY connection setup (See page 22), either
the ISO button or the IC button will activate any outside equipment connected to
the RELAY connector on the rear panel of the Base Station.
• Push-To-Talk Mode — To set the Headset for Push-To-Talk (PTT)
communication, with the power off, press and hold the volume-down T and
ISO buttons while you press and release the power button. You will hear “Power on, Headset #, Version #,
Hands-Free off” in the earpiece.
Press and hold the IC1, IC2 or ISO button while talking.
• Hands-Free Mode — To set the Headset for Hands-Free (HF) communication, with the power off, press
and hold the volume-up S and ISO buttons while you press and release the power button. You will hear
“Power on, Headset #, Version #, Hands-Free on” in the earpiece. When set up for Hands-Free
communication, the Headset can be operated in either HF or PTT.
• ISO Lockout Mode — To set the Headset with the ISO feature locked out, with the power off, press and
hold the IC1 button while you press and release the power button. You will hear “Power on, Headset #, Version
#, ISO off” in your Headset earpiece. When set up for the ISO Lockout mode, the ISO button will operate
the same as the IC1 button, in either hands-free or PTT communication.
To reset the ISO feature for normal ISO button communication, with the power off, press and hold the ISO
and IC1 buttons while you press and release the power button. You will hear “Power on, Headset #, Version #,
ISO on” in your Headset earpiece.
• Lights-off Mode — To prevent the power and transmit lights from coming on during headset operation,
press and hold the IC2 button while you press the power button to turn the headset on.
To return the lights to their normal functions, turn the power off and on again without pressing the IC2 button.
NOTE: The above settings are saved in memory and only need to be repeated when you want to change between HF and
PTT operation. When changing modes, if both power lights begin blinking, turn the Headset off and begin again.
Hands-Free and Push-To-Talk mode settings affect both IC and ISO. Individual adjustment is not possible.
• Push-To-Talk Mode Operation — Press and hold the IC1, IC2 or ISO button while speaking. In PTT
operation, audio will be transmitted only while you are pressing the IC1, IC2 or ISO button.
• Hands-Free Mode Operation — Quickly press and release the IC or ISO button to “latch” the
transmitter on in the HF mode. Talk and listen, as in a normal telephone conversation. Press and release
the IC or ISO button again to “unlatch,” to end the conversation. If either button is held down for more
than a half second, the Headset will function as PTT.
NOTE: In Hands-Free mode, pressing the IC1 or IC2 button while latched in ISO will latch on IC.
Pressing the ISO button while latched in IC will latch on ISO.
