Zeromatic
While searching, the scanner stops if a
transmission triggers the squelch setting.
A narrow-band FM transmission can have
a deviation of +/- 5 KHz, and the actual
total bandwidth, including the tails of the
sidebands, can be even greater. However,
search intervals smaller than that can stop
your scanner short of the correct (center)
frequency.
The Zeromatic function allows the scanner to
find the correct center frequency for search
banks SR3, SR4, SR5, SR6 and SR7. Zeromatic
automatically tunes the step-increment
frequency closest to the center frequency.
To activate Zeromatic:
1. Press FUNC then 0. “Zeromatic ON.”
appears briefly, then “ZM” appears.
2. To turn Zeromatic off, press FUNC then 0
again.
“ZM” changes to “zm.”
