Rotary Knob/On Button

Press and hold the Rotary knob to turn the MTM800 Enhanced on.
The Service Provider can program the Rotary knob to one of the
following uses:
• 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).
• List control – the knob is used to scroll lists (e.g. Talkgroup lists)
or menu items. In this case volume control is always via the
menu or external accessories (if present).
• 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.

Emergency Button

Press and hold this button to enter Emergency Mode.
When the MTM800 Enhanced is powered down, press and hold this
button to power On in Emergency Mode or in standard mode (as
programmed).

Numeric Keys

The MTM800 Enhanced supports the one-touch feature that allows
you to select or activate commonly used features by pressing and
holding a Numeric key.
The required time you need to press the Numeric keys to activate a one-
touch function is set as default to 1 second. This time may be set,
however, by your Service Provider.
