feature screen.
Multi-Function Knob (MFK)
MFK
is the on/off button of your radio. See
Turning On the Radio on page 26
for the procedure to
power up and down the radio.
In addition, there are programmable features available for
MFK
. The two programmable features are
as the following.
Mode Change
Turn
MFK
to scroll the channel or zone list.
Volume Change
Turn
MFK
to increase or decrease the volume level of the speaker. Fast turn of
MFK
makes coarse
tuning of the volume level; slow turn of
MFK
makes fine tuning of the volume level. The display
shows the volume level and bars to indicate the current level. The level of last selected volume
before the radio powers down remains the same when the radio powers up.
The radio by default is set to use the primary feature. Short presses of
MFK
toggle it to work on either
the secondary or primary feature.
The main display only shows the icon of secondary feature; the main display does not show the icon of
primary feature.
The secondary feature has an inactivity timer. This timer starts when the secondary feature is left idle.
Your radio returns to primary feature when this timer expires.
If the
MFK
is set to operate only one feature other than On/Off the radio, Volume Change should be
the only feature applied to
MFK
.
Consult your dealer or system administrator for the best options available for
MFK
.
Keypad
You can use the 3 x 4 alphanumeric keypad to access your radio features. The keypad functions in a
manner similar to a standard telephone keypad when entering numeric digits. When the keypad is
used to edit a list, each key can generate different characters of the alphabet. The following tables
show the number of times a key needs to be pressed to generate the required character.
