3.1.2  1W Transmitter module 
The Exciter’s front panel controls and indicators are: 
•  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 
when linked with PGM800Win. Slow Flashes indicates VCO 
(synthesizer) out of lock. Unequal Flashes indicates internal 
communication error. 
•  Microphone Socket – not used.

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 
carrier operations
.” 
Refer to 
Figure 4
 on the page 7, for the locations of the indicators.
