MUTE status indication.
• ON: Normal operating mode
• Standby: Transmitter turned off manually or remotely
• Fault OFF: Transmitter forced off due to fault condition
• ON/FB: Transmitter power folded back. Conditions causing the foldback
may by temporary and could possibly be cleared by pressing the ON button.
If, after pressing the ON button to reset the foldback, the ON/FB indication
resumes the malfunction will need to be determined and the transmitter
repaired (see Section 6 for fault log listings).
• PS MUTE: A temporary fault condition caused by a power supply related
fault. If underlying fault clears, the mute condition will be lifted and the
transmitter returned to normal operating mode. If the mute continues, the
underlying fault will need to be determined and the transmitter repaired (see
Section 6 for fault log listings).
• RF MUTE: A temporary fault condition caused by an RF related fault. If
underlying fault clears, the mute condition will be lifted and the transmitter
returned to normal operating mode. If the mute continues, the underlying
fault will need to be determined and the transmitter repaired (see Section 6
for fault log listings).
