Rotary Knob; Emergency Button; Function Keys - Motorola MTP850 Basic User's Manual

Rotary Knob

The Service Provider can program the Rotary knob to one of the
following uses:
1. Dual control – the knob is used as both a volume control and to
scroll through lists. Press the knob to toggle between volume and
list control (default programming).
2. List control – the knob is used to scroll lists (e.g. Talk group lists)
or menu items. In this case volume control is always via the Side
keys.
3. Volume control – the knob is used only as a volume control; turn
clockwise to increase the audio volume level.
Press and hold the Rotary knob to lock it, press and hold it again to
unlock. Powering Off also unlocks a locked Rotary knob.
