Introduction
Prepare for Use
The RL8873 Locator is specially designed to detect sondes and
camera systems, and with the RT8872 Transmitter is capable of
detecting buried power cables, CATV cables, gas and water pipes,
sewer lines, telephone cables, ber optic cables with sheath.
For Sonde and camera head locating a signal is generated by the
sonde or camera head and the receiver detects the signal giving the
user proximity cue to determine its location.
The transmitter emits a signal that is conducted or coupled to a
conductors. The receiver detects the signal. You can locate the relative position of the buried conductor by following the tracing signal.
As you unpack your Locator and Transmitter, make sure
there is no shipping damage and all the parts are
included.
Both units have batteries already installed.
When you need to change batteries, battery compartments are located the back of the “head” of the receiver
and the back of the transmitter. Open the compartments using a Phillips screwdriver. Install the six C
batteries as marked in the receiver and eight C batteries
in the transmitter.
Changing Operating Program or Program a Preset Frequency Set
uNote: MyTana ships the RL8873 programmed to 512 Hz frequency. If you wish to change frequencies, or store multiple
frequencies (presets), follow the steps below. Programs and frequency sets can be changed at anytime using this process.
To select a new frequency or preset a new set on the
RL8873 LOCATOR/RECEIVER
1. Press, and hold depressed, the POWER ON Button.
2. Pressing the GAIN DOWN Button will toggle through avail-
able congurations. The RL8873 oers the following modes:
u 512 - oers 512Hz Camera/Sonde locating mode only
u CAL- selected for calibration of system
(for authorized use only)
u U3- oers the following frequencies:
(camera/sonde mode) – 512Hz, 640Hz, 8kHz & 33kHz
(line mode) – passive 50hz & 60hz, passive rF, 512hz,
640hz, 8khz, 9khz, 33khz, 65khz, 82khz, 200khz, 478khz
To select or preset frequencies beyond 512, toggle to U3 mode.
3. Once in U3, release the POWER ON Button.
“PRO” will be displayed at the top of the LCD.
4. Short press the FREQUENCY Button to toggle to the
desired frequency.
5. Select the displayed frequency by holding down the
FREQUENCY Button for 2+ seconds. The top of the LCD will
display the preset/program number for this frequency, and
will increase by one each time a new frequency is selected.
If you do not want to program more presets, skip to #7.
6. Short press the FREQUENCY Button to toggle to the next
desired frequency, and repeat #5.
7. Pressing the POWER ON Button will exit the setup menu
and save the selected frequencies for availability during
normal operation.
uIf you ever need to change your Locator from Line mode
to Camera/Sonde mode — follow steps 1 and 2 above to
return to 512 (Sonde) mode. Release buttons.
To select a new frequency or preset a new set on the
RT8872 TRANSMITTER
1. Press and hold depressed the POWER ON Button.
2. Pressing the INFORMATION Button will toggle through
available congurations. Repeat pressing until U5 is
displayed in the Frequency indicator section of the LCD.
3. Once in U5, release the POWER ON Button.
“PRO” will be displayed in the LCD.
4. Press the FREQUENCY Button to toggle through the
available frequencies.
5. To select and store the desired frequency press the
INFORMATION Button. The program/preset number of the
selected frequency will be displayed on the LCD.
6. Continue to toggle through and select the desired
frequencies,
7. Pressing the POWER ON Button will save the selected
frequencies for availability during normal operation.
uOnce presets are saved and you want to change
frequency: Power On, and push to select the
frequency you want.

Absolute Signal Strength
The RL8873 Locator receiver provides the operator with a
direct measurement of the receiver’s signal strength. The
measurement is displayed with three numerical digits (ex: 485)
located at the bottom of the LCD display. The measurement
range is from -100 to 999 indicating a very week signal (-050)
to a very strong signal (999).
Absolute Signal Strength is independent of the GAIN setting
or meter reading. It gives the operator information about the
actual amount of signal being radiated from the conductor
and received by the receiver.
Measuring Absolute Signal Strength at any time is done by
reading the number at the top of the LCD display. The Absolute Signal Strength is displayed even when the meter reading
is o scale (too high or too low).
Gain Change Indication
The GAIN up and down Buttons are used to increase and
decrease the gain in small amounts. If the meter reading is
very low, pressing the GAIN UP Button will center the meter
reading to mid-scale. Likewise, if the meter reading is very
high, pressing the GAIN DOWN Button will center the meter
reading to mid-scale.
Digital Depth Estimate
The RL8873 Locator estimates the depth automatically. The
depth is displayed at the top of the LCD display in feet or
inches. Digital depth is useful in quickly determining the depth
of the conductor during path locating.
To change the Depth Measurement from CAMERA/SONDE to
LINE Mode, hold the Frequency Key for three seconds and the
next setting will appear.
uCaution must be exercised when using the digital depth
feature, as tilted magnetic elds and adjacent conductors can signicantly inuence this measurement. The
operator should periodically check for adjacent conductors and tilted magnetic elds when taking push Button
depth readings.
Low Battery
The RL8873 Locator will indicate low
battery condition by displaying low battery
icon at the bottom right of the LCD screen.
