SmartLock
®
Option.
Provides two external controls for the SG-230
Smartuner
®
: Locking function prevents retuning
despite changing antenna loads (e.g., from passing
trucks, or from driving beneath an overpass);
Reset function forces the Smartuner
®
into the
retune cycle until the signal is transmitted again,
or allows receiver/scan operation in a broadband
antenna mode. (Smartuner
®
is bypassed).
