■ The following parts are required for adjustment

The antenna connector of this radio uses an SMA termi-

nal.

Use an antenna connector adapter [SMA(f) – BNC(f) or

SMA(f) – N(f)] for adjustment.  (The adapter is not provided
as an option, so buy a commercially-available one.)

When the antenna connector adapter touches the knob,

draw out the knob to mount the connector.

Use the interface cable (KPG-36) for PC tuning or the lead

wire with plug (E30-3287-18) and screw (N08-0535-08) for
panel tuning.  Connct the plug to the universal connector of
the radio and tighten the screw.

The lead wire with plug (E30-3287-18) and screw (N08-

0535-08) terminals are as follows.  Numbers are universal
connector terminal numbers.

1. When connecting the plug to the universal connector of

the radio, a short circuit may occur.  To prevent this, be
sure to turn the radio 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 figure.

3. Do not connct an instrument between red or black and

GND.
