2. Power Meter
3. Deviation Meter
4. Digital Volt Meter
(DVM)
5. Oscilloscope
6. Frequency Counter
7. Ammeter
8. AF Volt Meter (AF VM)
9. Audio Generator (AG)

12. Regulated Power Supply
*The test equipment which is not used for adjustment is contained in this table.
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.)
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.

Useful if ammeter equipped
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.
