It is also bypassed when it is not powered, or a fault or abnormal condition
prevents its normal operation
4 TX indicator Lights when the 1 kW amplifier is switched to the transmit mode
5 FAULT indicator Lights when a fault in the 1 kW amplifier does not allow normal operation. In
this case, the amplifier remains in the bypass mode until the fault is corrected.
Flashes when an operational problem, for example, high temperature or
excessive VSWR, activates the corresponding protection circuits and causes the
amplifier to reduce its output power or temporarily switch to the bypass mode
6 Air intake vents Intake vents for cooling air, with removable covers that provide access to the
