13. 8Ω Dummy Load
14. Regulated Power Supply
■ Antenna connector adapter
The antenna connector of this transceiver uses an SMA
terminal.
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.)
■ Repair Jig (Chassis)
Use jig (part No.: A10-4125-03) for repairing the transceiv-
er. Place the TX-RX unit on the jig and fi t it with screws.
The jig facilitates the voltage check and protects the fi nal
amplifi er FET when the voltage on the fl ow side of the TX-
RX unit is checked during repairs.
■ Battery Jig (W05-1011-00)
Connect the power cable properly between the battery
jig installed in the transceiver and the power supply, and
be sure output voltage and the power supply polarity prior
to switching the power supply ON, otherwise over voltage
and reverse connection may damage the transceiver, or the
power supply or both.

Note: When using the battery jig, you must measure the
voltage at the terminals of the battery jig. Otherwise, a
slight voltage drop may occur within the power cable, be-
tween the power supply and the battery jig, especially while
the transceiver transmits.
