3.1.2 1W Transmitter module
The Exciter’s front panel controls and indicators are:
• Carrier Switch - momentarily keys the transmitter ON while
• Carrier Switch - momentarily keys the transmitter ON while
pressed (used for test purposes only).
• On LED - is lit when transmitting
• Line Sensitivity – not used.
• Supply LED - is lit when DC power is applied. Fast Flashes
• Line Sensitivity – not used.
• Supply LED - is lit when DC power is applied. Fast Flashes
when linked with PGM800Win. Slow Flashes indicates VCO
(synthesizer) out of lock. Unequal Flashes indicates internal
communication error.

3.1.3 70W Power Amplifier
The power amplifier is maintenance free, only LED indications are provided for the user. The
amplifier module has a large nominal bandwidth (500-1000MHz) designed platform. The units
of the base station are customarily tuned to achieve a +/-0.1dB gain variance over the band of
764-776MHz (700MHz models) or 851-869MHz (800MHz model). Attempting to fix a faulty
unit outside manufacturer’s premises can irreversibly damage it. The 10dB attenuator of the
connecting set must be attached at the input of the PA in order to adjust RF input to 100mW
(+20dBm).

As per Industry Canada Radio Standard Specification #131, paragraph 5.3:
“The manufacturer's rated output power of this equipment is for
single carrier operation. It should not be used for multiple
single carrier operation. It should not be used for multiple
carrier operations
.”
