Power On/Off
h Power On – Press and release the Power button (PWR). A voice prompt in the ear piece will say “Battery
Level”, and the red power lights near the corners of the A and B buttons will turn on. After a short time, one
light will go off and the other will change to green, indicating the Belt Pack is ready for use. The STATUS
indicator on the base station will momentarily indicate the ID of the Belt Pack. The green power light will be on
steady whenever the Belt Pack is ready, but not transmitting.
NOTE: While the Belt Pack is transmitting, the green power light will be ashing.
h Power Off – Press and hold the PWR button for approximately two seconds. A voice message in the ear
piece will say “power off”, and the green power light will turn off.
ISO (Isolate) and A, B (Intercom)
Use the ISO button to talk to other wireless Communicator users and the base station operator. Pressing ISO on the Belt
Pack will also send audio to AUX OUT if the AUXILIARY OUT light on the front of the base station is on. Use the A and B
buttons to communicate via the wired intercom channels and the base station operator. When the ISO button is pressed,
ISO RELAY is activated.
Operating Modes
h Push-To-Talk ONLY Mode Operation – In PTT operation, audio is transmitted only while you are pressing
and holding the A, B or ISO button. When you release the button, transmission stops.
h Hands-free Mode Operation – Quickly press and release the A, B or ISO button to “latch” the transmitter on.
Talk and listen, as in a normal telephone conversation. Quickly press and release the same button again to
“unlatch,” and end the conversation. The base station operator can unlatch all Communicators by pressing the
UNLATCH button on the base station.
NOTE: In the hands-free mode, if you are latched in A, B or ISO, quickly pressing/releasing either of the other
buttons will latch on that button.
Also in the hands-free mode, if you are latched in A or B and then press and hold the ISO button, it will function as PTT.
When you release the ISO button, the Communicator will revert to the latched A or B.
Refer to Communicator indicator light functions, Appendix A (pg. 30).

the ear piece as the volume increases one step. If you press and hold the ▲ button, repeating beeps will be
heard as the volume steps up to maximum. When maximum volume is reached, “maximum” will be heard in
the ear piece, and it will be repeated until you release the ▲ button.
h Volume Down Adjustment – Each time you press and release the volume-down ▼ button, a beep will be
heard in the ear piece as the volume decreases one step. If you press and hold the ▼ button, repeating
beeps will be heard as the volume steps down to minimum. When minimum volume is reached, rapidly
