1. Introduction
a. Servicing the F3 COMPACT includes fault finding, repair and maintenance and is
designed to be simple and fast thereby reducing the amount of time a detector is unusable.
Repair and maintenance is based on line replaceable units which can be fitted to a detector
without the need for adjustment or calibration. Additionally, serviceable line replaceable units
can be exchanged between detectors as required.
b. Line replaceable units are components or sub assemblies of the F3 COMPACT that can
be purchased from Minelab for the purpose of repairing the F3 COMPACT. Line replaceable
units include the following:
3004-0044 Coil Kit
3004-0045 Coil Pivot Kit
3004-0046 Shaft Kit
3004-0047 Camlock kit
3004-0048 Armrest Kit with Slide

c. Servicing the F3 COMPACT can be conducted within the field (under clean and dry
conditions) or at local service centres. No special tools are required, but it is recommended
that the F3 COMPACT Service Tool Kit be used.
d. Servicing the F3 COMPACT is restricted to the exchange of line replaceable units
following the identification of a faulty sub-assembly. Servicing DOES NOT include any repairs to
printed circuit boards as this is only conducted at a Minelab facility.
e. This manual should be read in conjunction with the F3 COMPACT Operations Manual.
Additionally, from time to time, Minelab will issue Technical Service Notes which serve to
supplement the information contained in this manual.
f. Any questions regarding this manual or any repair procedure can be directed to Minelab

2.1 Mechanical Testing
a. Confirm all parts and accessories are present and in good working order. Unpack the
detector and prepare for use. Figure 2 identifies the major components of the F3 COMPACT.
Mechanical testing and inspection includes checking:
• the detector for any obvious signs of damage,
• coil movement is smooth in both axes and holds its position without drooping,
• the skid plate is firmly attached and has no holes or cracks,
• shafts extend and retract smoothly and the camlocks hold the shafts firmly in location,
• the shaft hinge moves freely when the handle is down and locks into extended position
when the handle is up,
• the battery lid opens and locks, the battery lid tether is in good condition, and the battery
lid O-ring is clean and in good condition,
• the handle slides up and down freely locking into position,
• the armrest extends and retracts smoothly,
• the armrest strap is in good condition,
• the earset dust caps are in good condition, and
• sensitivity and On/Off knobs do not turn unless lifted and rotated and then spring back
into the locked position when released.
b. The detector must pass all mechanical tests and checks to be considered acceptable for
operational use.

2.2 Functional Testing
a. Functional testing is used to confirm the serviceability of an F3 COMPACT before it is
returned to the field for use and whenever doubt exists about its serviceability. The F3 COMPACT
must pass all tests to be considered serviceable and ready for use. Whenever a line replaceable
unit is replaced or a repair is conducted, all functional testing must be completed.
b. Functional testing requires a ground balance test piece. The ground balance test piece
simulates mineralised ground which results in an alarm from the detector. A mineralised “hot”
rock or adequate amounts of local mineralised soil is suitable. Alternatively, a ceramic floor tile
or clay roof tile may be suitable for use as a ground balance test piece.
c. The Switch On Test. The switch on test checks that power is correctly supplied to the F3
COMPACT and internal diagnostics discover no system fault. The test is conducted as follows:
• Prepare the detector for use.
• Hold the coil at least 600mm (24in) away from the ground and any metal objects.
• Ensure the sensitivity knob is set to the default position 4.
• Switch on.
• Ensure that four or five rising tones occur over approximately 12 seconds. A steady
threshold tone should be heard a few seconds after the rising tones finish.
d. Noise Cancel Test. The noise cancel test ensures the F3 COMPACT successfully
completes the noise cancel procedure required whenever local electrical interference is present.
The test is conducted as follows:
• Hold the coil stationary and at least 600mm (24 in) off the ground and away from any
metal objects during the test.
• Press and immediately release the Noise Cancel button. (Figure 4)
Figure 3: Switch On
Page 7
F3 COMPACT Service Manual
_______________________________________________________________________________________________________________________
7
Note
The coil should not be moved nor should metallic objects be brought near the coil during this
procedure.
• If functioning correctly, the noise cancelling procedure will commence with two single
beeps followed by 45 seconds of sharp double beeps and finish with four single beeps.
• During the 45 seconds the F3 COMPACT scans the environment searching for the source
of any electrical interference. Once detected, the detector will automatically select a
different operating frequency to eliminate or reduce the interference.
e. Audio Reset Test. This test confirms the audio reset button (also the ground balance
button) and the associated wiring and circuitry operates correctly. The objective is to ensure the
threshold tone returns to its correct volume if altered from its steady state. The test is
conducted as follows:
• Hold the coil at least 600mm (24in) off the ground and away from any metallic objects.
• Induce a threshold tone change in volume by slowly moving the coil toward a metal
object and once the threshold tone increases in volume hold the detector stationary.
• Once the threshold tone has increased in volume, press and immediately release the
green audio reset button. (Figure 5)
Note
If the ground balance button is not immediately released the F3 COMPACT will commence the
Ground Balance procedure.
Figure 4: Noise Cancel
Page 8
F3 COMPACT Service Manual
_______________________________________________________________________________________________________________________

• Within two seconds the threshold tone should return to its correct level
f. Ground Balance Test. This test confirms the F3 COMPACT is capable of ground balancing
against mineralised ground. In doing so, it confirms the correct operation of the ground balance
button, coil and associated circuitry. The test is conducted as follows:
• Ensure hands and arms are free of metallic objects (watches, rings etc) and that no other
metallic objects are near the coil.
• Keep the detector stationary and away from ground or metal objects, press and hold the
ground balance button for five seconds then release the button.
Note
This action will cause the F3 COMPACT to delete the previously stored ground balance condition.
Unless this is done the detector will remember its last ground balance condition regardless of the
unit being switched off or the batteries removed.
• Slowly move the ground balance test piece from approximately 150mm (6in) above the
coil towards the centre of the coil and confirm that a rise in threshold tone occurs. This
confirms that the detector is detecting the mineralised content of the ground balance
test piece.
• Press down and hold the ground balance button whilst slowly moving the ground balance
test piece from approximately 150mm (6in) above the coil towards the centre of the coil
(and touching the coil). Then, move the ground balance test piece away from the centre
of the coil to a distance of 150mm (6in).
• Repeat this process until the ‘Ground Balance OK’ tone consisting of a short high-pitched
double beep occurs. This tone confirms the ground balance procedure has been
completed correctly.
• Release the ground balance button and confirm that a steady low volume threshold tone
remains.
Figure 5: Audio Reset

• Confirm the ground balance is correct by moving the ground balance test piece from
approximately 150mm (6in) above the coil towards the centre of the coil. If there is no
alarm from the ground balance test piece the ground balance procedure is functional.
Note
Where the ground balance test is conducted using local soil Figure 6 illustrates the procedure to
be followed.
Note
Successful ground balancing occurs within 5 to 10 seconds. Where the ground balance test piece
or local ground conditions are not sufficiently mineralised the ‘Ground Balance OK’ tones may
take up to 25 seconds to complete.
g. Earset Test. This test confirms the earset is operating correctly and is conducted as
follows:
• Plug the earset into the detector as shown in Figure 7.
• Switch on the detector and confirm the threshold tone is audible using the earset.
• If an earset speaker On (4523-0027) is being tested check that the tones can also be
heard from the detector loudspeaker.
• If an earset speaker Off (4523-0025), identified by green band on the earset cable near
the plug, is being tested check that tones can only be heard in the earset and not the
detector loudspeaker.

h. LED Test. This test confirms the visual indicator (lights) can be enabled and operate
correctly. To conduct the test:
• Turn on the detector.
• Pass the coil over a metal object and check no LEDs are turned on.
• Press and release the LED button and check that a single LED is turned on when no metal
objects are near the coil.
• Pass the coil over a metal object and check that an increasing number of LEDs illuminate
as the target volume increases.
• Check that pressing and releasing the LED button toggles the LEDs on and off.
i. Battery Level Test. This test ensures that battery level indicator is operational, and is
conducted as follows:
• Turn the detector on.
• Press and hold the noise cancel button then press and release the LED button and then
release the noise cancel button.
• Confirm a series of LEDs illuminate indicating the level of battery power remaining.
• After three seconds the battery level indicator will extinguish and normal operation will
resume.
j. Test Piece Test. This test should be conducted in an environment that is free from
electrical interference and an earset must be connected. The test is conducted as follows:
• Ensure hands and arms are free of metallic objects (watches, rings etc) and that no other
metallic objects are near the coil.
• Set the sensitivity control to the default position 4 then switch on the F3 COMPACT and
confirm a steady threshold tone is present.
Figure 7: Connecting the Earset
Page 11
F3 COMPACT Service Manual
_______________________________________________________________________________________________________________________
11
Note
Maximum sensitivity is only available 30 seconds after the threshold tone is heard. Do not test
the F3 COMPACT with the test piece until 30 seconds after the threshold tone is heard.
• Hold the test piece above the middle of the coil with the rounded end (containing
metallic target) away from the coil.
• Move the test piece towards the centre of the coil until it lightly touches the coil then
move it sideways off the coil.
Figure 8: Test Piece Procedure
• Confirm a faint but clear response (change in threshold tone and pitch) is heard.
• If the test piece is not heard conduct an audio reset and repeat the test.
Note
The test piece test can only be conducted with the sensitivity control in the green position
(Sensitivity No 4). When the sensitivity control is not set to the green position it is the
responsibility of the user to provide an appropriate target with which to confirm the sensitivity of
the detector satisfies operational requirements.
k. Sensitivity Control Test. This test confirms the sensitivity control allows the operator to
make adjustments to the sensitivity of the F3 COMPACT. The test is conducted as follows:
• Set the sensitivity to the default position 4.
• Turn on the detector.
• Conduct the test piece test (refer to Section 2.2.j). Check that a faint but clear audio tone
is heard and that more than one LED illuminates.
• Decrease the sensitivity of the F3 COMPACT by rotating the sensitivity knob counter
clockwise to position 2. A single low pitched beep will be heard to prompt the operator
that the sensitivity is being decreased.
• Conduct the test piece test again and ensure no audio or LED response occurs.
• Move the sensitivity knob to position 4 and confirm a double beep occurs. This prompts
the operator that default sensitivity (position 4) has been selected.

• Rotate the sensitivity knob clockwise to position 6 and confirm that a single high pitched
beep is heard.
• Conduct the test piece test and confirm that a louder audio response and an increased
number of LEDs are illuminated when compared to the previous position 4 or 2.
Note
Regardless of minimum sensitivity at least one LED will remain illuminated providing an earset
speaker Off is not connected to the F3 COMPACT.

3.3.2 Main PCB Assembly
a. When the line replaceable unit 3004-0053 Main PCB Kit is supplied by Minelab no
assembly is required. However, in the event a main PCB is salvaged from one detector for use in
another, it is important to check for correct assembly before fitting the main PCB to the
detector. Check for correct assembly as follows:
• Check that the six way ribbon cable is connected to the main PCB.

4 Fault Finding Procedures
4.1 Introduction
a. A functional test failure can generally be repaired by replacing one or all of the line
replaceable units.
b. The F3 COMPACT is designed so that line replaceable units can be exchanged between
detectors without the need to calibrate. This means that where spare parts are not available
and more than one detector is faulty, then parts from one detector can be used to make another
serviceable. For example, if detector # 1 has an unserviceable coil and detector # 2 has an
unserviceable battery compartment, then the coil from detector # 2 can replace the coil on
detector # 1 thereby producing a serviceable detector.
4.2 Trouble Shooting Table
a. The following table identifies a number of faults and provides recommended solutions.
The suggested solutions should be investigated in the order they are listed.
Problem Recommended Solutions
Detector will not switch
on
● check batteries are installed correctly
● replace batteries with fresh batteries
● replace battery compartment
● replace main PCB
Detector will not switch
off
● remove batteries
● replace Main PCB
After switching on the
detector makes no
sound from speaker
● check for tone using the earset, turn LEDs on
● if there is tone through earset – replace the speaker
● if there is no tone through earset – replace main PCB
Threshold Tone is too
loud
● ensure area is free from local electromagnetic interference
● conduct Audio Reset
● conduct Noise Cancel
● check coil plug is tight
● replace coil
● replace main PCB
On switch on, the “Coil
Fault” tone occurs - “low
pitched double tone
every five seconds”
● check the coil plug is firmly secured
● inspect coil cable for damage – if no damage replace main
PCB
● if damaged replace with new coil
On switch on, the
“Equipment Fault” tone
occurs – “low pitched
slow oscillating tone
(ee-aww, ee-aww)
● turn off then on
● replace the switches
● replace main PCB
After working in hot
conditions, detector
makes a loud noise
● conduct Audio Reset
● check coil plug is tight
● replace coil
● replace main PCB
