Hi Brad
At manual explain something about it but I don't know if it will help.you. i hope yes:
Expert Button
Your AT-7000 has a control button and LED inside the case that may prove useful in certain?
situations. To access this ¡°expert¡± control, carefully remove the top of the case by unscrewing the?
four screws that hold it on. The button and LED are located on the PC board near the front panel?
on the left. Use caution when transmitting with the cover removed; high RF voltages may be?
present. LDG recommends that you use an insulated rod to press the button.?
The following functions are available:?
Full reset: press and hold the button while powering on the radio and tuner. Hold for at least ??
second after powering up. The LED will light for about 6 seconds, go off for ? second, then flash?
back on for about ? second before going off. All memories will be cleared.?
Manual Bypass: Press the button for less than ? second, then release to put tuner in bypass?
mode. The LED will blink once.?
Memory Tune: Press the button for less than ? to 2.5 seconds to start a memory tune cycle. As?
you hold the button down the LED will light to indicate you are in the proper time interval.?
Release the button while the LED is lit. The tuner will automatically default to a full tune cycle if?
no parameters are stored for the present frequency.
Full Tune: Press the button for more than 2.5 seconds to start a full tuning cycle, even if?
parameters are stored for that frequency. As you hold the button down, the LED will light, then?
go out; release the button after the LED goes out.?
The LED will light during any tuning cycle. When a memory tuning cycle ends, the LED will?
simply go out if the tuning cycle was successful. After a full tuning cycle, the LED will simply go?
out if the achieved SWR was higher than the previously stored value. This indicates that new?
parameters were not stored. If the achieved SWR is lower than the saved value, the LED will?
blink three times fast to indicate that new parameters were saved. The LED will blink once if the?
SWR is the same as the stored value.?
Three slow blinks indicates that RF power was lost during the tuning cycle. Adjust your?
transceiver as necessary and begin a new tuning cycle
