Functions. Refer to Figure 3C-18.
(1) Frequency Display. Liquid crystal digital
readouts provide a continuous display of both the
active frequency and standby frequency when the
system is in the frequency mode. System mode is
controlled by the CHAN push-button switch. When the
system is in the channel mode, the upper digital
display reads CH (channel) and a channel number (1
through 9), while the lower digital readout displays the
frequency of the displayed channel number. When the
system is in the program mode, the upper digital
display will read P (program) and a channel number,
while the lower digital display will read the frequency of
the displayed channel. In all modes, a small TX will
appear at the right end of the upper digital display
when the system is transmitting.
(2) Frequency
Transfer
Switch.
The
frequency transfer switch is a momentary push-button
switch, placarded with a two-headed vertical arrow,
located to the right of the digital display.
(a) Standby Entry Mode. Pressing the
frequency transfer switch with the unit in the standby
entry mode causes the frequency displayed in the
active digital display to interchange with the frequency
shown in the standby digital display.
(b) Active Entry Mode. While the unit is
in the standby entry mode or the channel mode,
holding the transfer switch pressed for longer than
2 seconds will cause the unit to enter the active entry
mode. While in the active entry mode, momentarily
pressing the transfer switch will return the unit to the
standby entry mode.
(c) Channel Mode. When the unit is in
the channel mode, pressing the transfer switch will
return the unit to the frequency standby mode. The
channel frequency will become the new active
frequency and the last active frequency will become
the new standby frequency. If the unit was in the
active entry mode prior to entering the channel mode,
pressing the transfer switch will return the unit to the
standby entry mode.
