SINGLE KEY TESTS

Frequency Select (CLR)
Select a frequency by entering "CLR" followed by a
channel number (0000 - 4808), normal band (3610 - 1208),
talk around band, followed by "CLR". This function allows
the synthesizer to be placed on a channel that is not pro-
grammed in the radio. A channel number can be entered with
or without leading zeroes.
Stop Transmiter (END)
This END key unkeys the transmitter. It DOES NOT
change the state of the bandswitch line.
Default Conditions (RCL)
RCL key resets the Digital Signal Processor to the do
nothing state (i.e. RX and TX audio off), sets the microproc-
essor ports back to default state, resets to the beginning of
the frequency set, sets the bandswitch line to the normal
band, and displays [FSxx #01].

Mode (STO)
STO returns the radio to the power-up state. I.e.
[PASSED] appears in the display and the radio returns to the
normal mode of operation.
Volume UP (VOLUP)
The VOLUP command causes the radio to increment
the volume setting by one step. There are 16 possible steps.
The volume setting affects the receive audio and the audible
user tones. A visual prompt is seen in the display of the new
volume setting ranging from 00 through 15, for example
(VOL - 04].
Volume Down (VOLDN)
The VOLDN command decrements the volume setting.
A visual prompt is seen in the display as described above.
Frequency Set Select ( )
The ( ) command allows the user to select a particular
frequency set that is programmed in the radio and set the
synthesizer to that channel. The prompt [FSET?] is displayed
and the user must enter the two (2) digit index number
obtained from the PC programmer printout of the frequency
set table. If a frequency set is specified that is greater than
the number of frequency sets programmed in the radio.
[ERROR] will appear in the display and 3 short beeps will
be heard. The first frequency in the frequency set specified
is always the default when a new frequency set is selected,
for example [FS03 #01] would indicate frequency set 03 and
the number 01 element of that set is currently active.
Increment Frequency (1)
The (1) command increments the radio to the next fre-
quency in the selected frequency set. If the highest frequency
in the frequency set is being displayed the first frequency in
the frequency set will be "wrapped around" and displayed.
Decrement Frequency (4)
The (4) command decrements the radio to the previous
frequency in the selected frequency set. If the active fre-
quency is already the first frequency in the set the radio will
wrap around to the highest frequency in the set.
