The FMTX100M is designed for continuous reliable transmission,
however the fans must be periodically checked for correct operation
and free airflow.
The front panel display shows the transmission frequency, forward
power level (
FWD
), reflected power level (
REF
) and multiplex input
levels.
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 LCD display shows all main parameters so no further menus are
provided or required (except frequency setting detailed above). During
normal operation, therefore, the menu buttons do not have
any function.
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).
