The frequency on which
the RX is operating does
not match any of the
channel frequencies
defined in the Channel
Plan for that band. Check settings of RX using Monitor
Screens and Command Screens.
Specifically check that the correct channel
is selected and that the frequency set for
that channel is correct. • Use Configurator to check settings.
Check the Channel Plan to be sure it is
correct.Be sure all settings match the
transmitter settings.
• If message persists even when
operating on a frequency that matches
the channel plan, unit may have
suffered internal failure. Send unit for
service.

the RF section of the RXU. In an RCU-only system, this is normal -
there is no RXU to detect. None.

failed. Send unit for service.
In a system with both RXU and RCU:
Check connection between RXU and RCU. • Use Monitor Radio feature of
Configurator to list errors.
• Use Configurator to check settings. Be
sure all settings match the transmitter
settings.

The RX is unable to lock on
the incoming signal. • Check Error Code Monitor Screen for
errors.

Screens and Command Screens. Be
sure they match transmitter. Specifically
check channel and frequency, COFDM
Bandwidth.
• Check connection between antenna
and RXU.
• Check connection between RXU and
RCU.

and BER. See Section 3.4.6 on page 3-
