The following parts are required for
adjustment
1. Antenna connector adapter
The antenna connector of this radio 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.)
2. Repair Jig (Chassis)
Use jig (part No.: A10-4082-03) for repairing the TK-2160.
Place the TX-RX unit on the jig and fit it with screws.
The jig facilitates the voltage check and protects the final
amplifier FET when the voltage on the flow side of the TX-RX
unit is checked during repairs.
3. Battery Jig (W05-0909-00)

Useful if ammeter equipped.
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.
When using the battery jig in user mode, the transceiver
assumes that a lithium-ion battery pack is attached to the
transceiver. In adjustment mode, battery type detection is
not performed. Refer to page 10 for details.
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, between the
power supply and the battery jig, especially while the
transceiver transmits.
