LiberatorMAX Headset
Operating Instructions
1) Power-Up
Turn Volume Control clock-wise to turn on headset
1 to 3 audible beeps will indicate level of battery charge when
headset is powered up (1 beep = low, 3 beeps = high)
Headset will be on channel last used
Headset will search for an existing “network” to join, or create
its own network if one isn’t found
LED Status Indicator will start Yellow, then turn Green
Headset will begin sending/receiving audio within 6 seconds
There will be a verbal (spoken) indication of the current channel
Volume Control will adjust received audio volume
As other headsets on same channel are turned on, they will join
the network if they are on the same channel
2) Mobile Radio PTT / Mic Mute / Channel Change Button
On CSB-900MAX and CSB-902MAX headsets, the lower
button on the right-hand cup functions as a Push-To-Talk
switch for the mobile radio connected to the Base unit. Press
to transmit, release when done.
On the CSB-901MAX and CSB-905MAX headsets, the lower
button on the right-hand cup functions as a Microphone Muting
switch: press once to mute the mic, there will be two audible
beeps; press again to un-mute the mic, there will be two beeps
at a different pitch.
3) Channel Change – All Fire Wireless Headsets
To change channels, hold down both lower buttons on the left-
hand and right-hand cups for 5 seconds. The headset will
increment by one channel and give a verbal announcement of
the current channel. The buttons can then be released. If the
buttons are held down, the headset will advance the channel
once each second.
All headsets must be on the same channel to remain
connected as a network (unless the operator is intending to
join another network).
NOTE:
If using a Portable Radio with the headset, it must be
turned off or disconnected when changing channels, or it will
be inadvertently keyed to transmit.
