■ Universal connector

Use the interface cable (KPG-36/36A) for PC tuning or
the lead wire with plug (E30-3287-28) and screw (N08-0535-
08) for panel tuning. Connect the plug to the universal con-
nector of the transceiver and tighten the screw.
The lead wire with plug (E30-3287-28) and screw (N08-
0535-08) terminals are as follows. Numbers are universal
connector terminal numbers.
Caution
1. When connecting the plug to the universal connector of
the transceiver, a short circuit may occur. To prevent this,
be sure to turn the transceiver POWER switch off.
2. Since the RX AF output is a BTL output, there is a DC
component. Isolate this with a capacitor or transformer
as shown in the fi gure.
3. Do not connect an instrument between red or black and
GND.
