A small amount of charge will continue to drain from the batteries while the transmitter is in sleep mode.
To conserve battery life, do not leave batteries in the transmitter when they can easily be removed, and
always remove batteries when the transmitter is not being used.
Transmitter Housing Requirements
For maximum transmitter range and battery life, the slots in the drill housing must meet minimum length
and width requirements and be correctly positioned. DCI recommends at least three slots, each at least
1/16-inch or 0.0625 in. (1.6 mm) wide and equally spaced around the circumference of the housing. For
accuracy, slot measurements must be taken from the inside of the housing.
For the long-range FX transmitter (15 in./38.1 cm long), the slots must be at least 8.5 in. (21.6 cm) long
and begin at least 2 in. (5.1 cm) but not more than 3 in. (7.6 cm) from the front of the transmitter, as
shown below.

For the extended-range FXL transmitter (19 in./48.3 cm long), the slots must be at least 13 in. (33 cm)
long and begin at least 2 in. (5.1 cm) but not more than 3 in. (7.6 cm) from the front of the transmitter, as
shown below.

FXL Transmitter Housing Slot Requirements
Both the FX and FXL transmitters are 1.25 in. (3.175 cm) in diameter and must fit snugly into the housing.
It may be necessary to wrap the transmitter with tape or O-rings to prevent it from rattling in the housing.
The index slot in the front end cap of the transmitter should fit onto the anti-roll pin (key) in the housing for
proper alignment of the transmitter in the housing.
