5-30 Volume increase and decrease keys
These two keys allow the volume of the receiver to be
varied between minimum and maximum. They will auto-
repeat if held down for more than half a second.
5-31 Store into memory key
The
key is used to store the current receiver
frequency and mode into the current memory channel.
The legend Stored .. on the receiver's display confirms
operation, and appears for about 5 seconds in the top left
corner. Keying in a memory number before pressing
will use that memory.
5-32 Memory preview key
The
key is used to preview, rather than recall,
the frequency contained in the currently selected memory.
The memory's stored frequency is displayed in the top
left corner of the LCD for about 5 seconds. If no data is
stored in the memory, the frequency 000.00 is displayed.
A particular memory may be examined by keying in its
number then pressing
or
will step through memory channels.
5-33 Change VFO key
The
key swaps between active and background
VFOs (A and B). If no data has been previously stored in
the background VFO, the current contents of the active
VFO are copied to the background VFO which is then
recalled... nothing appears to happen on the LCD in this
situation as the contents of the two VFOs are identical.
Each VFO contains nearly all of the current operating
conditions of the receiver, including frequency, mode, filter,
PBS, volume, treble, bass, squelch, IF gain, AGC speed
and tuning step size for
Note: The Background VFO information is lost when
power to the receiver is switched off.
5-34 Mode select keys
These keys, contained in a group of three, are used to
directly select the reception mode as an alternative to
stepping through a list of modes with the front panel
buttons. When any of these keys is pressed the mode
specified first is selected unless that mode is already in
use, in which case the second mode is chosen.
Foe example, to change from AM mode to USB mode,
the
key would be pressed twice. Subsequent
presses would then toggle between LSB and USB modes.

5-35 Number keys
The numeric keypad is used to enter frequencies, step
sizes and memory numbers. The receiver will display
keystrokes in the top left corner of its display as they are
entered until input is completed or a long time elapses
(about 20 seconds after the last keystroke).
The
key is used when keying frequencies to enter
fractions of kHz or MHz as desired. It is not needed when
entering whole numbers.
5-36 Backspace key
Pressing
will delete the last keypress from your
entry. This only works with the number keys while the
current keyed input is displayed on the LCD - it will not
undo an operation once it is completed.
5-37 Clear key
The
key will delete a whole line of entered digits to
allow a fresh start.
5-38 Memory recall key
The
key is used to directly recall memory
frequencies into the VFO. Each time the key is pressed,
the receiver advances to the next memory channel and
receives what ever frequency is stored. The
keys may also be used in conjunction with
to select the starting position for memory recall. When
the desired memory channel is displayed in the top left
corner of the LCD, the
and tunes the receiver.
Additionally the
key can be used in conjunction
with the numeric keypad to directly recall a memory. For
example to recall and listen to the frequency stored in
memory 25, press
is briefly displayed in the top left corner of the LCD to
confirm selection and the receiver is tuned to the memory
frequency.
5-39 Frequency entry keys
These keys complete a key entry and tune the receiver.
Frequencies can be entered in MHz or kHz and terminated
with the appropriate key. Frequency accuracy can be to
1Hz, with the receiver tuning to its nearest step (maximum
error is 1.4Hz).
For example, to tune to 15.070 MHz (which is 15070 kHz),
press
