The regulation algorithm is working with

This alarm may stay on the first minutes
after tuning to a new IP stream. If the
alarm does not clear, the input stream
may be a variable bitrate stream.

Too high

Internal temperature of unit is too high.

cooling is required.
Sequence error
Analysis of the sequence number of the
RTP layer indicates that IP frames have
been lost or that they have been
received out of order
RTP layer indicates that IP frames have
been lost or that they have been
received out of order
Typically this error is generated by
packets being dropped by some
equipment in the network, f.ex when a
link is overloaded.

Defective fan
There is an error with fan of the unit
Hardware problem.
No data received
No data received on Ethernet input for

stream
The most likely error is that there is a
set-up problem where IP address and
UDP port are not correctly configured.
The error can result from an error with
the transmitting unit or an error on the
network.

No lock
The IP receive channel is not able to
find an initial bitrate for the data
received.

Data lost
Stream received is incomplete and a

See ‘Sequence errors’. If you have
‘Sequence errors’ but not ‘Data lost’, all
frames are received but they are out of
sequence, or enough data is received
for the FEC engine to correct all lost
frames.
