Enter Reg
Backup all variable to paper first!
Trim value calculate by formula dBm = (sensorValue / aa); dBm = (dBm * -1) + bb;
So if you need to add +4db to 2400 band you need to set reg 75 b2400=15.48000 plus 4 = 19.48
To set register 75 to 19.48 you need to enter without delay 75 and wait 1 sec
You will see:
"reg =75
Enter call="
Enter without delay 19.48 and wait 1 sec
You will see:
"= 19.4800014495
MENU"
Press ENTER once and check 75 reg value.
Some garbage at end can be ignored.
If all ok disconnect usb and check power value.
