Button Functions
Frequency Select (F<n>)
Some channels have multi frequency base stations. In these situations you find one or
more frequency select buttons for the channel. These are usually labeled
F1 , F2 , etc. To
select a frequency, press the desired button. The green LED illuminates on whichever
frequency is currently selected. The LED may change automatically with the selection of a
different frequency on that channel by another console.
Some two-frequency channels may have only one button to select between them. In this
case, it may be labeled
F1/F2 . Pressing the button causes the frequency selection to
alternate between the two frequencies. The selected frequency has the adjacent LED
illuminated and the other extinguished.
Instant Select (F<n> SEL/CALL)
INSTANT SELECT is a direct way of simultaneously selecting both the channel and the
frequency for the channel. If your console is equipped with such buttons, you will not find
the standard
SELECT / CALL button, but rather buttons labeled like F1 SELECT / CALL ,
F2 SELECT/CALL , etc. Every INSTANT SELECT button has its own red Call/Busy
LED. Only one Call/Busy LED per channel is active at a given time, and this is on the
currently selected frequency. This is so that you may associate the receive activity with the
actual selected frequency. Usually the
INSTANT SELECT buttons with solid green
indicators show which frequency of the unselected channel is active. The INSTANT
SELECT button with the blinking green indicator shows which channel is selected as well
as the active frequency for that channel.
Instant Transmit (XMIT/BUSY)
Pressing and holding the INSTANT TRANSMIT button of a channel causes transmission
on that channel, without changing channel selection. The red LED of this button
illuminates whenever your console is transmitting.
Volume Adjust (VOL ADJ)
The volume of a channel, relative to the other channels, may be adjusted using the
channel’s
VOLUME ADJUST button and the CHANNEL VOLUME knob. Press and
hold the VOLUME ADJUST button and notice the display change to a two-digit value.
The value being displayed is the percentage volume currently set. To adjust the volume up
or down turn the
CHANNEL VOLUME knob clockwise (up) or counter-clockwise
(down) while the VOLUME ADJUST button is still being pressed. The display increases
or decreases in value. When you release the VOLUME ADJUST button, the display
returns to its previous display.
Mute/Volume Adjust (V ADJ/MUTE)
Press the MUTE button and the volume level of the channel is reduced to a predetermined
level. Press the MUTE button again and the volume is restored to its previous level. While
the channel is muted, the red LED of its MUTE button is illuminated. If the CHANNEL
VOLUME knob is turned while the MUTE button is pressed, the channel becomes
