The FMTX250 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 audio input
levels (ahead of any audio processing).
Audio levels will be optimised by the Audio Processor, however regular
checks of audio levels entering the transmitter are advised.
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:
