The Falcon F2 transmitter only performs this current draw test for five minutes after powering
on. The transmitter must be installed in the drill head for this test to be valid. Different drill
heads and slot arrangements will affect current draw and battery life.
Sleep Mode
All battery-powered DigiTrak transmitters go into sleep mode and stop transmitting to
conserve battery power if they are stationary for longer than 15 minutes. To awaken the
transmitter, rotate the drill string a half turn; a transmitter will not awaken if it lands on the
same roll position at which it went to sleep.
A small amount of charge will continue to drain from the batteries while the transmitter is in
sleep mode so it can monitor roll position. To conserve battery life, do not leave batteries in
the transmitter when they can be easily removed. Always remove batteries when the
transmitter is not being used to turn it off.
Note A transmitter will continue sending data for up to 10 seconds after the
batteries are removed. If you have removed the batteries and intend to
restart the transmitter in another frequency, wait until data has stopped
displaying on the receiver before reinstalling the batteries.
Transmitter Drill Head Requirements
For maximum transmitter range and battery life, the slots in the drill head must meet
minimum length and width requirements and be correctly positioned. DCI transmitters work
best with three slots that are equally spaced around the circumference of the drill head for
optimal signal emission and maximum battery life. The slots must be at least 1.6 mm wide.
For accuracy, slot measurements must be taken on the inside of the drill head.

* Ideal measurement. The DCI standard slot length of 21.6 cm and B distance of 5.1 cm
remains acceptable.
A transmitter must fit snugly in its drill head. It may be necessary to wrap the transmitter with
tape or O-rings and/or to use a drill head adapter for larger drill heads. Contact DCI Customer
Service for more information.
The index slot in the front end cap of the transmitter should fit onto the anti-roll
pin (key) in the drill head for proper alignment. Use roll offset if the transmitter’s
12:00 position does not match that of the drill head.
