■
This transceiver has a test mode. To enter test mode,
press [A] key and turn power on. Hold [A] key until frequency version appears on LCD. Test mode can be inhib-
ited by programming. To exit test mode, switch the power
on again. The following functions are available in test mode.

2.00 or later. Versions prior to 2.00 cannot be used.
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be con-
nected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with a
8Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
Transceiver tuning
■
(To place transceiver in tuning mode)
Press [S] key, now in tuning mode. Use [B] key to write
tuning data through tuning modes, and [Selector] to adjust
tuning requirements (1 to 256 appeares on LCD).
Use [C] key to select the adjustment item through tuning
modes. Use [A] key to adjust 3 or 5 reference level adjustments, and use [Side2] key to switch between Wide/Narrow.
Channel appears on LCD. Set channel according to tuning
requirements.

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 (W05-0909-00)
■
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.
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.
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.
