The SG-230 may be bypassed for broadband (untuned antenna) scanning lis-
tening. All you need to do is remove power from the Smartuner for 2 seconds
and reapply power. When the tuner comes back on, the tuning elements
remain out of the circuit until the coupler is activated by a transmitted signal.
If broadband operation is required during receive for scan operation, jumper
J-2 may be set to the "YES" position. This will drop the tuning elements out of
the circuit on receive only. Jumper J-2 is located adjacent to IC-7 on the
printed circuit board. If you open your Smartuner to access this jumper,
please use caution to insure that the waterproof seal is carefully placed prior
to refitting the coupler cover.
Setting J-2 to the 'YES" position is recommended if you are using a radio for
split band communications, scanning selective calling protocols or for ALE
(Automatic Link Establishment).

Jumper J-3 bypasses the coupler's memories. This means that each time the
coupler is used on a substantially different frequency, it will retune rather
than use previously stored information.
