GENERAL INFORMATION 

 
The BTD-2 will decode a single burst tone and give a momentary and/or latched output. If the BTD-2 MOD-1272 
is purchased then the unit will look for the 1800 Hz preamble of a Motorola MDC-1200 ANI packet in order to 
mute the speaker of the radio, so the packet is not heard.
