The following diagrams will assist you with installing the SMARTUNER with SGC
equipment.
6.1 Installation with SG-2000
The SG-2000 is shipped with all necessary connectors for installation of a
SMARTUNER™ and for installation of peripherals by means of the audio input/output
jack on the rear panel. You will see the connectors when you remove the Philips head
screws that hold the protective sheet metal cover over the rear panel connectors.
From left to right, these jacks provide the following:
J-502 SMARTUNER connections

6.2 INSTALLATION ON ALL RADIOS
The SMARTUNER requires only a source of +12 VDC (optional: +24 VDC), an RF
transmission line (RG-58/U up to 30 ft., RG-8 OR RG-213/U if over 30 ft.), plus suitable
ground and antenna systems. No band switch information, low power tuning, or
handshake is required, since the coupler tunes on RF voice or carrier. Power
consumption is normally less than 1 amp, allowing for use of small gauge wire. The
PCB is fully protected against power reversal. The output for a remote mounted tune
indicator, if desired, is strictly optional.
When installing your SMARTUNER, remember to allow for the power to be
disconnected from the battery during periods when equipment is not being used. This
will prevent draining the battery unnecessarily.
