E211 IF IC Error
* If any of E207, E208, or E210 occurs before or during the transmission, the repeater will transmit with the reduced transmit power
than normal. Even if all of these errors are cleared during in this transmission, the transmit power in this state is continued until the
end of this transmission.

Error Event /
Item Name
Hot Standby LAN The LAN connection between the Main and Sub repeaters under Hot Standby
Connection Error fails.
This error will be displayed when the following cases.
Case1. Detection Error between the Main and Sub repeaters at the start up
process. This error is displayed to both repeaters in this case.
Case2. Detection Error of the standby repeater at the active repeater when the
hot standby works as normal. This error is displayed to the repeater that was
acting as the active repeater. Then the standby repeater will start working as the
active repeater.
Check the network connection, IP Address of Private IP and Virtual IP, or the
network equipment / port permission.
Beacon Sync The sync signal from the Host Repeater (Primary) for Beacon fails under
Disconnect Conventional IP Network.
This error is not applicable for the repeater working as the host itself.
The below is the case depends on the setting of Host Repeater.
Secondary: When starting as the host due to the primary repeater failure.
Deselected: When failing to receive the sync from the host (or the secondary)
Check the networking connection.
Fan Error The pulse detection of the cooling fan rotation fails.
Check the cooling fan itself or the related circuit around it.
Power Supply The power supply voltage is below than the voltage preconfigured in "Power
Voltage Error Supply Lower Level" on FPU. The default value is "12.2V".
Check the power supply equipment or the FPU setting.
RX PLL Unlock The circuit block of RX PLL may have a problem.
Proceed the general circuit troubleshooting as the receiver.
TX PLL Unlock The circuit block of TX PLL may have a problem.
Proceed the general circuit troubleshooting as the transmitter.
Current The current consumption of HPA (High Power Amp) is abnormal.
Consumption There may be a possibility of an abnormality in VSWR, abnormality of the TX
(HPA) Error block circuit (Drive Amp, High Power Amp), or abnormality of Fan action.
Proceed the general circuit troubleshooting.
The temperature of Drive Amp is abnormal (too high).
(Drive Amp) Error There may be a possibility of excessive transmission continuation, abnormality
of the cooling fan action or an abnormality in the TX block circuit.
Temperature The temperature of TX Block is abnormal (too high).
(TX Block) Error There may be a possibility of excessive transmission continuation, abnormality
of the cooling fan action, or an abnormality in the TX block circuit.
Proceed the general circuit troubleshooting.
Temperature The temperature of TCXO is abnormal (too high).
(TCXO) Error There may be a possibility of excessive transmission continuation, abnormality
of the cooling fan action, or an abnormality in the TX block circuit.
Proceed the general circuit troubleshooting.
The temperature of HPA (High Power Amp) is abnormal (too high).
(HPA) Error There may be a possibility of excessive transmission continuation, abnormality
of the cooling fan action, or an abnormality in the TX block circuit.
Proceed the general circuit troubleshooting.
IF IC Error The calibration of IF IC is failed.
