Transceiver setting
IC-M700 with serial number 2500 and below
In the IC-M700, change the [TUNE] switch setting
from the “1” position to the “2” position. Confirm that
the [KEY] switch is in the “2” position. Refer to the IC-
M700 instruction manual page 9 for details.
[KEY] [TUNE]
Select “2” position.
Confirm “2” position.
Other HF transceiver
Some Icom HF transceivers have internal [KEY] and
[TUNE] switches. Suitable switch settings for the AT-
130/E are performed before shipping.
However, if a non-Icom automatic tuner was previ-
ously used, confirm the switch settings. Refer to the
instruction manual for details.
Non-Icom HF transceiver
Select correct settings for the start voltage and key
voltage. Refer to your HF transceiver instruction man-
ual for details.
