Other Icom HF transceivers
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 previously
used, confirm the switch settings. Refer to the instruction
manual for details.
Non
- Icom HF transceivers
Select correct settings for the start voltage and key
voltage. Refer to your HF transceiver instruction manual
for details.
IC-M700 with serial numbers 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 instruc-
tion manual p. 9 for details.
[KEY] [TUNE]
Confirm "2" position.
Select "2" position.
