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's transmitters
require three slots equally spaced around the circumference of the drill head for optimal
signal emission and maximum battery life. Measure slot lengths on the inside of the drill
head; slots must be at least 1/16 in. wide. DCI transmitters fit standard housings but may
require a battery cap adapter in some cases.

* Ideal measurement. The DCI standard slot length of 8.5 in. and B distance of 2 in.
remain 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 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.

Use only the battery cap that accompanied the Falcon F5 transmitter; other battery caps may
look similar but crush the batteries or make the transmitter too long to fit in a standard
housing.
