Instructions for setting up a BP200 for "Push-To-Talk"  or "Hands Free" full duplex mode
Push-To-Talk Mode — To set the Beltpac for push-to-talk (PTT) communication, with the power off,
press and hold the volume-down and ISO buttons while you press and release the PWR (power) button.
You will hear “Power on, Beltpac #, Version #, Hands-free off” in the headset earpiece. Press and hold the
IC or ISO button while talking.
Hands-free Mode — To set the Beltpac for hands-free communication, with the power off, press and
hold the volume-up and ISO buttons while you press and release the PWR (power) button. You will hear
“Power on, Beltpac #, Version #, Hands-free on” in your headset earpiece. When set up for hands-free
communication, the Beltpac can be operated in either hands-free or PTT.

NOTE: The above settings are saved in memory and only need to be repeated when you want to change between
hands-free and PTT operation. When changing modes, if both power lights begin blinking, turn the Beltpac
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 IC or ISO button while speaking. In PTT
operation, audio will be transmitted only while you are pressing the IC or ISO button.
• Hands-free Mode Operation — Quickly press and release the IC or ISO button to “latch” the
transmitter on in the hands-free 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 Beltpac will function as PTT.
NOTE: In hands-free mode, pressing the IC button while latched in ISO will latch on IC. Pressing the ISO
button while latched in IC will latch on ISO.
