3. Dwell Time: Dwell is the time in seconds the receiver remains on one frequency after
it locks onto a signal. Two Dwell-Time options are available: Finite Dwell and Infinite
Dwell. If your objective is to stop on each occupied channel briefly, then move on to the
next, set a Finite Dwell for any desired period between 0.1 and 29 seconds. If your
objective is to continue monitoring an occupied channel for as long as activity is present
(as when monitoring two-way traffic), then enter any time of 30 seconds or greater to
initiate the Infinite Dwell default.
To enter a new Dwell Time, advance the Edit Knob clockwise to the Dwell menu prompt:
A. Finite Dwell Time: Use the main keypad to keystroke in a two-number entry
between 0.1 and 29 seconds (0.1, 1.2, 5.0, 10, etc.). The entry will self-complete
automatically when the second number is entered:
B. Infinite Dwell Time: Use the main keypad to keystroke in a two-number entry of 30
seconds or greater. The program will automatically default to Infinite Dwell Time, and
the following message will appear in the Memory/Scan display:
At this point, you may exit MScan Setup to begin scanning, or you may edit the Dead
Time and Gaze Time settings. If you know the existing Dead and Gaze parameters are
acceptable for your task, exit now. If you do not know what they are or need to amend
them, continue with the setup procedure.
C. To Exit: If you elect to exit Setup at this point, press the Setup button. The switch
will toggle off, the Setup and MScan LEDs will go out, and the Memory/Scan display will
go dark until you initiate a new Memory/Scan function.
4. Dead Time: Dead Time is the interval the receiver will remain on frequency after a
signal drops out and the Squelch closes. This function holds the receiver on frequency
(or channel) between push- to-talk exchanges and during pauses in SSB speech or data.
To enter a new Dead Time, advance the Edit Knob clockwise to the Dead Time prompt.
Dead Time is adjustable from 0.1 second to 29 seconds (same as dwell time). Use the
main keypad to keystroke in a two-number entry (0.1, 1.2, 5.0, 10, etc.). The entry will
self-complete automatically when the second number is entered.
At this point, you may either Exit the PScan setup or continue on and enter a Gaze Time.
To Exit, press the Setup button.
