Wireless: How do I configure a WH200 beltpack from hands free mode to Push To Talk mode?

Instructions for setting up a WH200 for "Push-To-Talk"  or "Hands Free" full duplex mode
• Push-To-Talk Mode — To set the Headset 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 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 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.
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.
