Procedure for Observing the Predicted Depth
When the receiver (with 5.0 firmware) is at the FNLP and held level with the trigger in, the bottom window
will rapidly flash the predicted depth number accompanied by a solidly lit squiggle (“~”); the predicted
depth information is also displayed in the bottom window on the remote display. Should the trigger be
held in at any other location than the FNLP, the predicted depth in the bottom window will be invalid and
should be disregarded. The depth prediction feature requires pitch; should the pitch information become
unavailable, the predicted depth display (with trigger held in) will show only the squiggle in the bottom
window, and there will be no number for the predicted depth. This feature also requires that the ultra-
sonic distance be set prior to measuring the predicted depth.
Viewing the Transmitter’s Temperature and the
Receiver’s Battery Status in Percent of Remaining Life
While the trigger is held in, the top left window will display the signal strength (as with pre-5.0 firmware
versions) and the top right window will display the transmitter’s temperature in degrees Celsius as a
flashing number. When the trigger is released, the top right window will display for 2 seconds the
percentage of battery life remaining in the receiver’s rechargeable NiCad battery as 100, 90, 75, 50, 25,
10, 5, or 0, and the top left window will display the transmitter’s battery percentage remaining as 99, 90,
75, 50, 25, 10, 5, or 0. The pitch and roll information will resume 2 seconds after releasing the trigger.
Viewing the Receiver’s Battery Voltage
The receiver’s NiCad battery voltage is displayed only during the start-up process. The receiver battery
voltage is displayed for 2 seconds during initial start-up in the bottom window and is in tenths of a volt,
i.e., 155 is 15.5V DC. A fully charged, properly operating NiCad battery is approximately 16.5V to 17.1V
DC. At 14.0V DC, the battery is considered discharged.
Off Feature
To shut the receiver off, click the trigger as if you are taking an ultrasonic measurement. As soon as the
unit begins to beep click the trigger 4 or more times (observe 4 or greater in the bottom window). The
receiver’s windows will all blank out, indicating the receiver is off. The battery need not be removed to
shut off the receiver.

Running Time Meter
Display
The running time meter tracks the operating hours for receivers
having 5.0 series and later firmware. To view accumulated run-
ning time hours, the receiver must be started with an “on by 4”
clicking sequence, as follows:
Place a battery in the receiver. Click the trigger once followed
by 4 rapid clicks. The hours will be displayed in the top left win-
dow (up to 999), minutes in the top right window, and thousands
of hours in the bottom window.
To exit the running time meter display, click the trigger once and
the unit will shut off. To restart, click the trigger.
