• Turn the IC-706MKIIG's power
OFF when connecting the AT-
180, otherwise, the CPU may
malfunction and the AT-180
may not function properly.
• The OPC-742 is required when
using the AT-180 and a 2
m linear amplifier.

[TRANSCEIVER]
connect [ANT 2] to the
AT-180. When using an HF to 2 m
wide antenna, use a duplexer
between the AT-180 and antenna
since 2 m signals do not pass
through the AT-180.
