 Not lit when the cutback voltage is over 1.2 volts (reflected power is high)
2.6.8 FANS Status LED
Status that shows if all amplifier fans are currently operational. The MXi amplifier has four cooling fans in the fan
assembly. This status does not indicate which fan is faulty but just that one or more of the four fans are not operational.
The operator can return to the AMP submenu that is accessed from the COMB submenu to determine which of the four
fans is faulty.
When the amplifier is turned ON, all the fans are turned on.
 Lit when all four fan rotational status are true, this only happens if the fan is actually rotating.
 Not lit when one or more of the fans are not rotating or the amplifier has been turned OFF.
2.6.9 SubMenu Select Buttons
The fourth line of the LCD holds select buttons that will control operations. Note that the Amp1 RST control button also
helps the operator to identify which screen is currently displayed since all the submenu screens look identical except
for this menu button marking.
There are only two active controls on this submenu as described below:
 Amp1 RST = VSWR Reset Control for Amplifier #1
 OUT = Returns LCD to the Comb Interlock LCD Screen.
