User Manual

SPECIFICATIONS
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
