The transmitter is designed for continuous reliable transmission,
however the fans must be periodically checked for correct operation
and free airflow.
Correct operation is confirmed by a front panel green STATUS LED.
Should this turn red, the transmission system may shut down its RF
output and will, in any case, require URGENT attention.
The following are LCD display fault indicators and their meaning:
TEMP!
The system is running too hot and has shut down the RF
output as a safety precaution. Check the fans for correct
operation. Also check the antenna system, including all cabling
(and/or filters and/or combiners where fitted) for correct
operation. The FWD! indicator (see below) will also show and the
standby transmission system (where used) will have activated
(TTL control).
REF!
! The system has detected a fault in the antenna system
and has shut down the RF output as a safety precaution. Check
the antenna system, including all cabling (and/or filters and/or
combiners where fitted) for correct operation. The FWD!
indicator (see below) will also show and the standby
transmission system (where used) will have activated (TTL
control).
FWD!
The system has detected there is no forward power. This
may be due to one or both of the above symptoms, due to a PLL
failure, or due to excessive power setting. The standby
transmission system (where used) will have activated (TTL
control).
Ensure air vents and internal air tunnels are kept free from dust during
operation.
The cooling fans should be replaced after 80,000 hours of cumulative
operation. This life rating is for guidance only and is subject to ideal
environmental operating conditions. Replace any fan that fails or
becomes slow or noisy, immediately. It is recommended that
replacement work must be carried out by the manufacturer or an
approved agent.
