10.2 Lamp for RF
When the RF SWITCH in the main menu is set to ”ON”, and the POWER SET percent is
more than 0,this green lamp is light.
10.3 Lamp for AUDIO
If the audio input mode is set to be the stereo, the lamp is light.
10.4 Lamp for REMOTE
In the page of General Set, if Remote is enabled, this yellow light is illuminant.
10.5 Lamp for TEMP
When the amplifier temperature is higher than 65
℃
, the red lamp is light; higher than 70
℃
,
to decrease temperature, and to protect amplifier, the system will try to decrease output power; if
temperature exceeds 75
℃
,it will power off immediately.
10.6 Lamp for VSWR
If reflected power is higher than 5% of rated power, the lamp is light; higher than 7% of
power, it will decrease output power to decrease reflected power; when it is higher than 100W, it
may happen that: the software power off the output, or the hardware circuit switch off the power
supply, then power on again.
10.7 Lamp for GENERAL
If this lamp is light, it may happen that: forward power is more than 105% of rated power,
voltage of power supply is higher than 53V or lower than 45V, driver current is higher than 2.2A,
at least one amplifier's current is higher than 18A,and one amplifier has no current.
When the lamp is light, and accompanied by a power decreases,it shows that the reflection
power is too big.In a certain period of time, reduce power still can not get out of this state, the
system will shut down and restart the amplifier.
If forward power exceeds 120% of rated power, the system will shut down the amplifier
immediately, and then restart it.
