Starting the Dual-Frequency Transmitter
in Single-Frequency Mode
Loading Batteries
for Single Mode
1. Remove the battery cap, and hold the transmitter vertically with the battery
compartment down and the front end pointing up (see diagram).
2. Load two C-cells (or a SuperCell battery) into the battery compartment with
the positive terminal(s) entering first.
3. Replace the battery cap while rotating the transmitter in this vertical position
until the cap is flush with the end of the battery compartment.
4. Power up the receiver and verify that you see Low Fre on the main menu
screen.
5. Select Locate from the receiver’s main menu screen, and click the trigger.
6. You will see SH above the thermometer on the left side of the screen to
indicate the transmitter is in single-high mode.
7. Verify that the signal strength is approximately 565 when the receiver is 10 ft
(3 m) from the transmitter (in the housing), and record the value.
Sleep Mode (Automatic Shutoff)
The Eclipse transmitter will shut down (go into “sleep” mode) to conserve battery power if it is stationary
for 15 minutes. To “wake up” the transmitter, simply rotate the drill string.
Transmitter Housing Requirements
To achieve maximum range and battery life for all of DCI’s transmitters, the slots in the housing must be
long enough and correctly positioned. Slot measurements should always be taken from the inside of the
housing.
DCI recommends at least three slots equally spaced around the circumference of the housing. The slots
must be at least 1/16 or 0.0625 in. (1.6 mm) wide. The position and length requirements of the housing
slots for the different Eclipse transmitters are given below.
For the standard and dual-frequency transmitters (15.00 in./381.0 mm long), each slot should begin at
least 2.0 in. (51 mm) from the front or index cap end of the transmitter and must be at least 8.5 in. (216
mm) long (see figure below).
