The depth measurement units (centimeters or inches) and remote channel setting can be changed only
during start-up (see “Changing Depth Measurement Units” and “Changing the Channel Setting” below).
After the start-up process, the windows will display pitch, roll, and distance if there is an active transmitter
within range (see Tracking Mode display below). If an active transmitter is not within range, 1999 will
appear in the bottom window and the top windows will be blank. If the bottom window is not displaying
1999 and there is no active transmitter within range, an unknown signal is present.
To turn the receiver off:
The receiver will automatically shut itself off if no signal is received for 15 minutes.
To turn off a receiver when a signal is present, click the trigger once and, during the tone, quickly click 4
times. All windows will blank out, signifying that the unit is off.
To turn off a receiver with pre-5.0 series firmware when a signal is present, the battery must be removed
manually.
(For more information on the 5.0 series firmware and operating/display differences, see “Clicking vs.
Holding the Trigger” and “5.0 Series Firmware Functions” in this section.)

After charged batteries are loaded into the transmitter (positive end
first), the receiver enters “tracking” mode and will display pitch in the
top left window, roll (12 positions) in the top right window, and depth
(or distance) in the bottom window. With the DigiTrak System it is not
necessary to push any buttons to receive pitch, roll, or depth/distance;
this information is updated and displayed automatically. The flashing
squiggle (“~”) in the top left window indicates that pitch and roll
updates are being received from the transmitter. For the best results,
wait for two squiggles with the same pitch/roll information before
giving a steering command to confirm the accuracy of the data.

Clicking the trigger versus holding the trigger will initiate different
modes with your receiver. When the trigger is held in (trigger up) the
receiver is in the “locating” mode, and the top left window will display
signal strength. Also displayed in the top left window, along with the
signal strength, are the plus (“+”) and minus (“–”) symbols. These
symbols are the key to locating the transmitter (see Locating Section).
The bottom window will display the predicted depth, along with a
flashing squiggle. The top right window will flash the transmitter’s
temperature in degrees Celsius.
