then press SAVE and select a number for these settings. By default it would
assign the minimum number available.
(17) Lastly, long press POWER button to shutdown after the test is done.
All the settings will be saved and will be restored after next boot.
5.3.2 Search and Measure Nearby Emissive Source
In technical field, chances are it's clear there is a emissive source nearby
and its frequency needs to be measured. For instance, several people is
communicating using walkie-talkie in the public. The frequency they are on
needs to be found and the content of the conversation needs to be
demodulated. Traditionally this mission would be completed by cymometer.
Being referred to as "receiver searcher", it's effectively a receiver served by the
cymometer. However, the sensitivity of the cymometer is relatively low and
it's vulnerable to interference produced by emissive sources out of interest
(like mobile phone base station). Fortunately, the spectrum mode of KC908
offers a performance right on the sweet spot of speed, sensitivity, anti-
interference ability as well as frequency accuracy, in other words, an ideal
comprehensive performance.
(1) Connect the antenna and boot, enter SPECTRUM mode in MODE
menu. Enter frequency setting by pressing CENT button. Take the preset
scenario above as an instance. Normally walkie-talkie works between 300-
