Handset Ear Level (TRC Option C Only): 

 
1.  With a field radio talking on channel to the TRC, adjust RP304 to a comfortable level. 

 

Motorola MDC-1200 Decode Level Alignment: 

 
1.  Transmit a 1500 Hz test tone over the air at approximately 2/3 full system deviation (3.3 kHz wideband, 1.7 kHz 

narrowband). 

 
2.  Monitor TP501 with an oscilloscope and adjust RP501 for maximum amplitude, so that 700 mV p-p (250 mV RMS) 

is seen at TP501.
