Status messages

In certain situations, the EM 6000 display may show status messages and error messages.

For messages relating to errors that can impair function, the red triangle to the right of the display for the particular channel also lights up.

No Link

No transmitter connected.

Low Signal

The reception quality between the transmitter and receiver is poor (RF A or RF B below -85 dBm, LQI between 1 % and 19 %).

  • Check the transmitter’s radio link to the receiving channel and switch to a different frequency if necessary. See Establishing a radio link.

Low Battery

The transmitter’s batteries or rechargeable battery pack have little battery life remaining (less than 30 minutes).

  • Replace the rechargeable battery or batteries.

Sync ok

The synchronization of the receiving channel with the transmitter was successful.

Sync Fail / No Frequency

The auto setup function cannot provide any more free frequencies for the transmitter frequency range.

Sync Fail / Frequency Rejected

The transmitter frequency range is incompatible with the frequency set in the receiving channel.

Sync Fail / Timeout

The synchronization of the receiving channel with the transmitter was unsuccessful. The infrared interface for the receiver may not have been able to establish a link to the infrared interface of the transmitter.

  • Hold the transmitter in front of the infrared interface for the receiver correctly. See Synchronizing devices.

Sync Fail / Unsupported Encryption

AES 256 encryption is activated on the EM 6000 but the transmitter does not support it (SK(M) 9000).

  • Use an SK 6000 or SKM 6000 if you want to activate encryption.

Encryption Error / Sync Needed

AES 256 encryption was activated on the EM 6000 but is not synchronized to the transmitter yet. The encryption cannot be activated on the transmitter. Instead, it must be transferred via the Sync function.

Clock Error

There is a deviation in the clock rate of the word clock (> 120 ppm for 48 kHz or > 120 ppm for 96 kHz) or there is no external word clock.

RF Peak

The RF signal is too strong (> -12 dBm). There is a risk of overloading the receiver.

  • Increase the distance between the antennas and the receiver.
  • Use passive antennas instead of active antennas if possible.
  • If using active antennas, reduce the antenna amplification.

AF Peak

The audio level of the transmitter is too high (> -2 dBFS). The signal is at risk of overloading and becoming distorted.
