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, be-
tween the power supply and the battery jig, especially while
the transceiver transmits.
