Antenna Connector Adapter
The antenna connector of this radio uses an SMA termi-
nal. 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 switch-
ing 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 26 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 trans-
ceiver transmits.
