Care should be taken when 
selecting the proper output power 
for the T-2500-M. Higher power 
will give the greatest range but 
will increase the chance of counter 
detection. DTC recommends using 
the lowest possible transmit power 
that can safely do the job.  

The output power level is determined 

by battery selection: 

2 CR2 batteries (6 Volts) -- 250 mW, 

3 CR2 batteries (9 Volts) -- 500 mW,

4 AA batteries (6 Volts) -- 250 mW,

4 AAA batteries• (6 Volts) -- 250 mW

 

*optional AAA battery holder
