livestock and other animals by doppler positioning or triangulation.  It also transmits back data relative 
to activity, mortality, etc. by changing pulse rate.  It is FCC Certified and must be used with a valid 
FCC license, issued for telemetry uses, under Part 90.259 of the Rules.  It is preprogrammed at the 
factory to operate in the 217-220Mhz band.  Power output is 95mW.  The PT-90 is waterproof and 
includes a changeable, screw-on, antenna.  It uses a widely available CR123A Lithium battery or a LIR

the supplied magnet into the slot between to top of the transmitter and the collar.

collar battery compartment + (positive) end in first.  Screw on the battery compartment cap with a 
screwdriver or coin.  A small amount of Vaseline on the battery compartment cap "O" ring will allow 
easy cap removal and keep the battery compartment watertight.  Dispose of any used batteries properly.

Simply reverse it to start the transmitter working.  If you are using the LIR17335 rechargeable Lithium 
Ion battery and quick charger, please note that if a discharged battery is being charged, the LED

battery can be left in the charger indefinitely without being damaged.  The rechargeable battery can be 
recharged over 500 times before needing replacement.  Charge time is less than 3 hours.
