Preset Frequencies
The Preset Frequencies display is used to view the preset frequencies and select the one
used for leakage testing by the Seeker. Preset frequencies are numbered from 0 to 9 and
areconguredanddownloadedwiththeSeekerSetupsoftware.
The Seeker comes from the factory loaded with the following
preset frequencies; 121.2625, 127.2625, 133.2625, 139.2500,
and 146.2625 MHz.
After a few seconds in the Preset Frequencies display without
any action by the user, the display will revert to the Signal
Level display.
In the Preset Frequencies display, the FREQ icon at the top of the display will blink and be
followed by the preset frequency number.
To change the frequency selection, press the CHANGE button.
When entering the Preset Frequencies display or selecting a new preset frequency, the
numeric display will momentarily show the leakage frequency and tag frequency for the
preset channel. First the MHz digits will be displayed. After this, the fractional digits are
displayed. Finally a “t” is displayed followed by the tag frequency for the preset channel.
For example: For a frequency of 121.2625 MHz. with a tag frequency of 20 Hz., the display
will indicate:
121
2625
t 20
When the numerical display has cycled through the frequency information for the selected
channel, the display will resume indication of the signal level for that channel.
