any free space between the transmitter and the side walls of the housing. If necessary, fabricate an “insert” behind the transmitter to ensure a snug fit. When wrapping with tape, be sure that the pitch will not be offset. If more tape is on one end than the other, the trans- mitter will not be level in the housing. Also, be sure that metal-to-metal contact is avoided.

Before purchasing a new housing, place a transmitter inside and check for a snug fit. Also check that the index slot fits snugly over the key in the housing. If the key is too narrow, the transmitter can rotate and cause damage to the index slot. There are particular “wear patterns” that occur on transmitters that do not fit properly in the housing. If you send a transmitter to DCI for testing, please specify what type of housing you are using.

Because the transmitter’s antenna is positioned centrally (as shown on the previous page), it is important that the windows or slots in the housing (through which the signal is emitted) are positioned to allow the transmitter’s signal to emit with minimal restriction. The slots must number at least five and have a length of no less than 8 inches (20 cm). These slots must be centered directly over the midpoint of the transmitter. The width of the slots may be as narrow as necessary to maintain housing strength. (Drawings showing the proper slot width, length, and positioning can be obtained by request from DCI.) These slots must not have any filler material containing metal particles, e.g., liquid steel.

To install a transmitter in the housing:

1.Examine the transmitter to verify that there is no moisture inside the battery compartment, that the springs inside the battery compartment have not been permanently compressed, and that the tem- perature indicator (temp dot) located at the front end of the transmitter is not black.

2.Insert the correct number of C-cell alkaline batteries into the battery compartment with the positive end in first. Place cap over battery compartment and tighten. (See “Batteries” below.)

3.Place the transmitter in the housing with the index slot over the anti-roll pin positioned as discussed above in this subsection. The 12 o’clock position should correspond to the tapered or flattened sur- face of a typical directional drill head pointed upward.

4.Verify that the transmitter is emitting the appropriate amount of signal (see Operational Tests) and conduct other tests as discussed in the System Operating Instructions Section before you start drilling.

NOTE: Place the transmitter in the housing and verify that pitch readings remain the same when the housing is held level and rotated through at least four of the 12 clock positions.
