Note:
1)
“RC_CMD” determines where the TX On/Off command comes from:
“IO” means from Pin 1 of Dry Loop;
“Other” means from either Serial or Web interface.
2)
"FWD_CAL": Default value is "OK". "FWD_CAL" is used to calibrate the 100% FWD power level.

Note:
1)
"PDT" is the pre-set time for ADPC function which ranges from 0x0 to 0xF, and recommended value
is 0x5 which means about 7 minutes in "UPDATE3" part and about 10 minutes for the entire ADPC
process (all 4 steps together).
2)
"CFR" is the pre-set crest factor reduction level which ranges from 0x0 to 0xF. The lower the
parameter's value is, the harder the reduction of crest factor will be. And 0xF means bypass the whole
CFR function (No reduction at all).
Note: If ADPC (Pre-correction) is ongoing, the system will disable automatically the CFR
function (clipping) and will only resume the function after ADPC is finished.
3)
"ADPC" here has the same function as that in control mode (default user menu) but separates into 3
steps. And the control here and there (default user menu) sync up to each other. All 3 steps still have
to be run in strict sequence to get a complete compensation done. However going step by step gives it
a chance to monitor each step's performance more closely. Among all 3 steps, "UPDATE1" is to
compensate the linear distortion before band-pass filter, and "UPDATE2" is for the linear distortion
after band-pass filter. "UPDATE3" is for both linear and non-linear distortion in the whole
transmitting system (include both the power amplifier and the band-pass filter).
