If not enough power is applied for tuning (less than 5 watts), the display will flash
INCREASE POWER
three times and “QRO” (dah-dah-di-dah di-dah-dit dah-dah-dah) will be sent on CW. Increasing the input
power above five watts ends this message.
When input power is too high, the tuner enters a self-protection mode. The tuner will not allow any of its
relays to change. This feature is to prevent damage to your tuner.
If too much power is applied when tuning, the tuner will cease the tuning routine, flash DECREASE
POWER
three times and send “QRP” (dah-dah-di-dah di-dah-dit di-dah-dah-dit) on CW. This occurs
when the forward power exceeds 75 watts and the SWR is greater than 3.0, or when the forward power
exceeds 125 watts regardless of the SWR.
If more than 300 watts is applied to the tuner, the tuner will go into bypass mode, flash
OVERLOAD three
times and send “QRT” (dah-dah-di-dah di-dah-dit dah) on CW.
If the tuning process is activated under these conditions, the tuner will not start the tuning. It will indicate
the appropriate bounce code on the meter and display a warning message on the LCD.
