Operation
Basic operation
All functions are controlled through the seven front panel buttons. Each function is invoked when
the key is
released
. Some commands are indicated by the length of time you hold a button before
releasing it. There are three lengths of press: short (less than .5 seconds), medium (.5 – 2.5
seconds) and long (more than 2.5 seconds). This sounds a lot more complicated than actually it is;
this interface will quickly become familiar and easy.
Setting Options
All settings are retained in EEPROM memory indefinitely, even if power is disconnected.
Separate settings are stored for each antenna, except for LED On/Off and Antenna selection,
which are global settings that apply to both antennas.
Startup Options
Your AT-100Pro has three startup commands, invoked by holding down one or more keys while
powering up the unit (usually by plugging in the coaxial power connector).
Version display: Press and hold
Func
while powering up. This will display the version number
of the firmware in your tuner on the LED meters. The first digit of the version number is
displayed on the PWR meter, the second on the SWR meter. The LEDs use a one-of-eight
display, indicating 1, 2, 3, etc from right to left. In the example below, version 1.2 is displayed
(this is just an example; your version number may be different).
Version Display
All Reset: Press and hold
Func+Ant+Tune
while powering up. This will reset the unit to
factory defaults, and will erase all memories.
LEDs On/Off: Press and hold
Ant
while powering up. This will toggle the unit between
displaying the power and swr LED meter displays during transmit. These displays will be active
during a tuning cycle or after key presses regardless of this startup setting. You may want to
disable the LED meters when operating from battery power.
