OPERATION
bandwidth are used. From the numeric keypad, enter the step size
(in kHz). Terminate the entry by pressing the SETUP key. When
the setup key is pressed, the entry is momentarily displayed in the
menu, and the display increments to the PRE DWELL selection.
6.
The PRE DWELL parameter determines the time that the receiver
stops at each increment of a scan sequence, waiting for a signal to
break the programmed squelch threshold. The pre dwell time can
range from 0 to 1000, in 5 msec increments. Values ranging from 0
to 995 msec specify the pre dwell time in msec. A value of 1000
selects an infinite pre dwell time. Step values are rounded to the
nearest 5 msec increment. From the numeric keypad, enter the
desired Pre Dwell time, and terminate the entry by pressing the
SETUP key. When the entry is terminated, the value is momentarily
displayed in the menu, and the display increments to the SIG
DWELL selection.
7.
The SIG DWELL parameter determines the time that the receiver
remains on an acquired signal. The signal dwell setting can range
from 0 to 601, in 1 second increments. Values ranging from 0 to
600 specify the signal dwell time in seconds (0 to 10 minutes). A
value of 601 specifies an infinite dwell time. It the signal falls
below the squelch level before the timer expires, the scan resumes to
the next increment. From the numeric keypad, enter the desired
Signal Dwell time, and terminate the entry by pressing the SETUP
key. When the entry is terminated, the value is momentarily
displayed in the menu, and the display increments to the POST
DWELL selection.
8.
The POST DWELL parameter determines how long a the receiver
waits at an acquired signal’s frequency after the signal falls below
the programmed squelch level. The post dwell setting can range
from 0 to 61, in 1 second increments. Values ranging from 0 to 60
specify the post dwell time in seconds (0 to 60 seconds). A value of
61 specifies an infinite dwell time. From the numeric keypad, enter
the desired Post Dwell time, and terminate the entry by pressing the
SETUP key. When the entry is terminated, the value is momentarily
displayed in the menu, and the SETUP menu mode is terminated.
3.5.2 SCAN INITIALIZATION
Once the memory has been programmed, and the scan characteristics have
been selected, the scan operation is ready to be activated. To begin the
scan, press the SCAN key. The LED on the KEY lights, and the scan
operation starts. During the scan, the front panel displays, are
continuously updated with the current parameters for each increment of the
scan. During the scan, the front panel controls, except for REMOTE,
SCAN, and PAUSE, are disabled. When a Channel scan is initialized, all
of the parameters used for each increment of the scan are obtained from the
channel memory and the Setup menu. For F1-F2 type scans, only the start
