Introduction

Congratulations on your purchase of the Marshall RT Standard Transmitter. Designed for the harshest conditions in falconry, the RT
is the most rugged falconry transmitter ever produced. Now even more powerful, the RT is longest range transmitter available.

Operating Modes:

The RT transmitter is designed give the best range possible while hunting, but it is also
able to reduce duty cycle (slow down the pulses) to preserve battery life if your falcon is
out for an extended time. With this feature, the RT provides 7+ days of total battery life
on a new battery.

Battery Life Indication:

The RT will run 7 days continuously when a new battery is installed. The LED light on the
side of the RT indicates the current battery status

Green LED
– Normal Mode. Battery condition is good
.... Yellow LED
(and double beep) – Change Battery. The battery is getting low (2-3
days remaining)
....
Red LED
(and triple beep) – Battery almost dead, you have less than 1 day remaining
Note: the LED light is the latest technology and is super-efficient, it uses less than 1% of the transmitter's power.

Battery:

The RT uses the venerable 1/3N Lithium Photo Battery proven by
falconers for years. We recommend the Duracell DL1/3N.

The status of the transmitter is then indicated by the color of the LED light.
Note: If you lose your magnet, or prefer to use your transmitter without this feature, the RT can be
switched on and off by simply removing the battery.
