causes "DWL INFINITE" to be displayed. If the key is pressed while "DWL INFINITE" is displayed, the last
numeric dwell entry is redisplayed with the far left digit highlighted. The Memory/Scan edit knob can be used
to adjust the highlighted value. The DWELL key is also used as a terminator key when using numeric entry
keys to enter the dwell time. Refer to
paragraph 3.8.1
for details on dwell time operation.

THE STEP SIZE KEY AND LED
The STEP SIZE key is located below the alphanumeric display in the Memory/Scan section of
the front panel. This key is used to enter the step size parameter entry mode. The step size parameter serves
two functions: it defines the tuned frequency increment value when the STEP TUNE key LED is lit
(
paragraph 3.2.9
) and it defines the step size used in a frequency-to-frequency scan setup. The step size can
also be adjusted by entering the scan setup menu with the SCAN SETUP key (
paragraph 3.2.26
).
When the STEP SIZE key is pressed, its LED becomes lit and the alphanumeric display shows
the current step size with the most significant (far left) digit highlighted indicating resolution. Below is an
example of the alphanumeric display in the step size entry mode:
MEMORY/SCAN
S T E P x x . x x x k
where xx.xxx is the current step size value in kHz. Pressing the key again causes the highlighted position to
shift one digit to the right. Pressing the key while the least significant (far right) digit is highlighted causes the
most significant digit to be highlighted. The STEP SIZE key can also be used as a terminator when using the
numeric keys for entering the step size. This key is not functional while the receiver is actively scanning (i.e.,
the SCAN key LED is lit and the PAUSE key LED is not lit.
3.2.23
THE CHANNEL VIEW KEY AND LED
The CHANNEL VIEW key is located below the alphanumeric display in the Memory/Scan
section of the front panel. This key is used to view the frequencies stored in the receiver's memory channels.
The first press of the key causes the last viewed channel to be displayed in the Memory/Scan section
alphanumeric display. The memory channel number is displayed prefixed with an "s" for skipped channels or
an "i" for included channels. (Refer to
paragraph 3.2.31
for details on using the CHANNEL SKIP key and to
paragraph 3.2.30
for details on using the CHANNEL INCLUDE key.) The frequency stored in the current
channel is also displayed in MHz, with 10-Hz resolution. The following is an example of the standard channel
view display.
