Frequency Search
To manually search through the frequency range (COMM and NAV),
the Up Key or Down Key may be pressed at any time to select the
next higher or lower frequency. This uses 8.33 KHz steps in the
COMM frequency range and 50 KHz steps in the NAV frequency
range. The Up and Down Keys may be pressed repeatedly to continue
changing the selected frequency.
To automatically search the entire COMM frequency range for a
broadcasting signal, the Up Key or Down Key may be pressed and
held for one second. The Screen will display SEARCH as seen below.
The frequencies will either scroll up or down in 8.33 KHz steps
depending upon whether the Up or Down Key was used to initiate
the Search.
When a broadcasting signal is found, the word SEARCH will flash and
the SP-200 will stop temporarily on that frequency. If the broadcasting
signal is cut off for more than two seconds, the Search will resume
until another signal is found. When 142.975 MHz is reached during an
upward Search, the Search automatically continues at 118.000 MHz.
Likewise, when 118.000 MHz is reached during a downward Search,
the Search automatically continues at 142.975 MHz.
The Search may be canceled at any time by pressing the Clear Key.
The direction of the Search may also be reversed at any time by
pressing and holding the Up or Down Key (whichever is appropriate)
for one second.
It is very important that the Squelch be properly adjusted prior to
initiating a Search. The background static received with the squelch
off may be strong enough to disrupt a Search. If a Search gets “stuck”
on a frequency with too much background noise, increase the Squelch
or press and hold the Up or Down Key for one second to skip that
frequency and resume Searching.
