5. Gaze Time: Gaze represents the interval—in seconds-the receiver will wait for a
signal to appear on a quiet channel before moving on to the next. Longer Gaze Times are
useful when searching for CW, SSB, and some digital-mode signals where short pauses
or gaps may be present. Short Gaze Times are preferred for carrier-based signals like FM
and AM.
To enter a new Gaze Time, advance the Edit Knob clockwise to the Gaze prompt. The
Gaze interval is continuously adjustable from 0.01-29.9 seconds. Use the main keypad to
keystroke in a three number entry (0.01, 1.20, 5.00, 10.0, etc.). The entry will self-
complete automatically when the third number is entered:
At this point, the MScan Setup is complete. You may rotate the Edit Knob in either
direction to review your entries, or exit MScan Setup. To exit, press the Setup button.
The Setup and PScan LEDs will go out, and the Memory/Scan display will go dark until
you initiate a new Memory/Scan function
Important Note: Gaze, Dwell, and Dead Times are shared by both PScan and MScan
functions. When changing from one mode to the next, remember to check and—if need
be—reset these parameters.

4-39 INITIATING MSCAN:

To initiate an MScan, first make sure the Setup function is turned off and the Squelch
threshold is set to eliminate background noise and undesirably weak signals (as with any
scanner). Setting the Squelch is especially important when using Infinite Dwell, since the
scan function will not advance to the next channel while the Squelch is open. To initiate
the scan, press MScan, once:
The LED will illuminate and the Memory Scan display will show the PScan function,
current channel number, and Dwell Time. With each captured channel, the Aux
Parameters display shows the receiver parameters for that channel. You may halt the
scan sequence temporarily at any point by pressing the Pause button twice. Pressing it a
second time will resume scanning.
If Infinite Dwell has been selected, reception of any sufficiently strong, continuously-
transmitting signal to open the Squelch will halt the scan. To override and resume
