Place or mount the RBI in close proximity to the Kenwood mobile radio to be used. Connect the RBI with the provided
PG-4H Cable from the 8 pin modular jack marked "RADIO" to the Kenwood Microphone jack. Only Port 1 (140/DUAL) will
support a Dual Band radio. Port 1 is the only Port the 140 Mhz radio can be connected.
The RBI will support all 4 bands (140/220/440/1200) as follows:
If Port one is filled, Port 2 is for 220 only, Port 3 is for 440 only, Port 4 is for 1200 only. Basically, if the selected band is
unavailable on Port 1 it will go to the port hard assigned to that band.

Audio receive level from the Kenwood to the Controller is controlled by VR2 (R). The audio level from the Controller to the
Kenwood is adjusted by VR1 (T). Refer to your manuals for additional adjustments in your controller.
The Kenwood radio's need certain parameters setup before they can operate from the RBI. Things such as STEP, etc.
Since the memory channels in the radio aren't used we will reset the radio to default on all setup options. This can be
found in your Kenwood operating guide.
