Once alarms are cleared, you can slowly increase the exciter’s drive or lower the ATT value to
bring the amplifier back to the original level.
4)
RF-SWITCH: It is to turn the TX of the amplifier ON or OFF.
5)
AGC: This is the switch to turn ON/OFF AGC function and FWD-STARDARD is to set the target
AGC value.
6)
GRID-VOLT: It is highly NOT recommended to change any setting in GRID-VOLT without the
permission of the manufacturer. Unauthorized changes in GRID-VLOT may cause damage to the
amplifier and void the warranty.
7)
ALARM-PARA: This section is to set the threshold for all alarms including forward power alarm,
reflected power alarm, rejected power alarm, VSWR alarm, high current alarm, and
high-temperature alarm. We recommend keeping those settings unchanged because they are
pre-set and optimized for the application before leaving the factory. If they are changed without
the permission of the manufacturer, it may leave the amplifier in insufficient protection and may
cause damage to the amplifier and void the warranty.
8)
PARA-RESET: This is to restore all parameters back to default/uncalibrated settings. Every
amplifier’s parameters have been calibrated and optimized for its application. Please do not run
PARA-RESET unless it is suggested by the manufacturer.
9)
REMOTE-UPDATE: This is to upgrade the firmware of the amplifier. Please only upgrade the
amplifier with the permission or guidance from the manufacturer. Turning the amplifier into
upgrade mode will make it stop working immediately, and it loses its web pages access too. If the
amplifier is turned into the upgrade mode by mistake, the only way to bring it back is to power
cycle the amplifier.
