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
