What is preset tuning
Preset tuning setting provides fast tuning on your most-
used frequency.
What is emergency tuning
The Europe version, AT-130E, includes an emergency
tuner circuit for 2182 kHz operation separated from the
automatic tuner circuit. If any signal from the control
cable becomes abnormal, the emergency tuner is auto-
matically selected.
