Phone Mode/Radio Mode Operation

3
Your Ericsson rugged terminal combines phone and
push-to-talk radio features in a single terminal. One
clockwise turn of the mode control knob (3) changes the
mode from Phone Mode to Radio Mode and vice versa.
Once a call is made in Phone Mode, the call can be
changed to Speaker Mode by switching the mode con-
trol knob from Phone Mode (green) to Radio Mode (red).
The terminal operates in Phone Mode when the mode
control knob indicates green. While in Phone Mode, the
side volume key (1) may be used to adjust the volume.
The terminal provides full duplex audio like a standard
cellular phone while in Phone mode.
The terminal operates in Radio Mode when the mode
control knob indicates red. It operates like a mobile
radio on the cellular network with half duplex audio
(speak or listen, but not both simultaneously). While in
Radio Mode, the mode control knob can also be used to
adjust the volume settings. There are 7 volume settings
that can be achieved by turning the knob in a clockwise
direction.
Once a number is on the display, press the Push-To-Talk
(PTT) button (2) to initiate a call in Radio Mode and
