IMPORTANT!
Always reduce the RF Output power to minimum before changing
the transmission frequency. Once the new frequency is active,
slowly increase the RF output power control to provide the
required power output level. Re-calibration of the audio
modulation level should also be performed.
WARNING!
Never operate this device without a suitable 50 ohm load
connected to the RF OUTPUT socket, or without a suitably
installed and matched antenna system connected. Although the
output of this transmitter is protected against antenna load
faults, MIS-OPERATION MAY RESULT IN DAMAGE NOT COVERED
BY ANY WARRANTY.
IMPORTANT!
Correct operation of the cooling fans in this product is vital to
reliable continuous operation. Schedule bi-annual maintenance
checks. We strongly advise the use of a standby transmitter
system for use during maintenance events or fault conditions, to
prevent prolonged breaks in transmission.
IMPORTANT!
When cycling the power off, then on, ensure that the transmitter
is off for at least 10 seconds before re-applying power, to allow
the internal circuits time to fully reset. Failure to do so may result
in no RF output (PLL failsafe mode).
Consideration should be given to fitting a suitably rated UPS if
power interruptions are likely. Similarly, telemetry reset of power
may be advisable for transmitters in remote areas, or having
restricted access arrangements.
