check the assembly page to make sure all parts are
present.

Chapter 1 XLT
readjust clevis/lower rod length with the sping clip
buttons so that the search coil can be held near the
floor without requiring stooping over.
Assembly
2. There are rubber washers between clevis/lower
rod and loop ears. Use only nonmetallic washers,
fiber bolt, and thumbnut to secure loop/search
coil to clevis/lower rod.
3. Unlock "S" rod camlock and insert clevis/
lower rod into curved "S" rod so that stainless
steel spring clip buttons line up and lock into one
of the adjustment holes in the curved "S" rod.
Turn camlock to secure. The second or third
adjustment holes are suitable for average size
adults. Individuals 6' or taller should use the fully
extended position. Individuals well over 6' tall
should purchase the optional Tall Man Rod.
4. Unravel loop cable and wind the cable around
the clevis and rod assembly, first revolution over
the top of the rod. Wind cable all the way to the
top of the curved "S" rod, about five revolutions.
Use the black cable retainers, one near the loop,
and one near the top of the curved "S" rod, to hold
the loop cable in place.
5. Unlock control box rod camlock and insert
curved "S" rod so that stainless steel spring clip
buttons line up and lock into the rod on top of the
control box. The "S" rod is designed to curve up
toward the display. However, those who prefer to
sweep the loop close to their feet may desire to
assemble the "S" rod to curve down toward the
ground. Turn camlock to secure. Plug loop connector into control box, screw lock ring to secure.
7. Remove the protective paper from the two black
elbow cup foam pads. Carefully align pads on the
inside of the elbow cup, one on each side of the
center rod, and press firmly into place.
8. Adjust the elbow cup strap so that it is loose
enough for you to slide your arm in and out without loosening each time you want to set the detector down. The elbow cup strap provides extra
leverage and control. However, some prefer not to
use it.
9. Install battery as described in the next section,
decal facing down, with plastic tab and steel contacts
facing toward inside of battery compartment.
10. It should be noted at this point that the detector
may not work as expected indoors due to the high
degree of metals used in modern construction. It is
best to tune and practice out-of-doors to ensure
stable, predictable results. Additionally, freshlyburied targets will not produce the normal depth
and discrimination results of targets that have been
naturally lost and settled in the ground. Due to the
abnormality caused by digging a hole in the ground
matrix, and the sophistication of the ground rejection circuitry, it may take a number of years for
freshly-buried targets to respond at true depths and
discrimination accuracy. The best way to determine true detection depth is in real search conditions.
6. Grip the instrument by the handle, with your arm in
the elbow cup with strap secure, and sweep the loop/
search coil over the floor. If the instrument fit feels
uncomfortable, adjust the elbow cup by removing
and repositioning the bolt/thumbnut and installing
in one of the optional positions. If necessary,

CHARGER PLUG
A rechargeable battery (green decal) is provided
with your instrument. This battery can be recharged
hundreds of times as long as the battery hasn't been
stored for extended periods of time or overcharged.
Full charge can be achieved anytime during the
discharge cycle. When using the QUICK charger
setting use the Charging Hours chart on the following page for charge time. A full charge will last ten
to fifteen hours of normal use.
Battery life will vary with temperature, the number
of targets found, and the exact settings used. Six
hours is not unusual for extreme high performance
settings, backlight use, or for batteries that have
experienced extensive use.

Charging
1. There is no harm charging overnight using the
OVERNIGHT charger
setting regardless of the
battery's current condition.
However, before charging
with the QUICK charger
Charging
Hours
setting, determine battery
condition by inserting
battery into the instrument
and turning the instrument
ON. If the instrument will
not turn ON, or if voltage
tests eight volts or below,
charge five hours with the
QUICK charge. If the battery voltage tests any other
voltage, refer to the Charging Hours chart above for
proper QUICK charge time.
2. To charge, insert the charger plug into the battery
pack jack, located near the plastic tab and
metal contact points.
3. Plug the charger into a standard wall outlet.
(110 volts for USA models).
4. Again, the QUICK charger setting uses the
above chart for a specific charge time. OVERNIGHT is designed to charge the battery in as little
as fourteen hours. However, no harm will come to
the system leaving it charging for several days.
5. It is normal for the battery and charger to get
warm during use. However, if either the battery or
the charger gets too hot to hold or deforms due to
the heat, discontinue use and return for testing.

6. The battery will lose its charge during storage.
If stored inserted in your instrument, this loss will
be more noteworthy. It is recommended that the
battery be removed from the instrument during
periods of storage. It is not advisable to store rechargeable batteries for long periods of time without use. If however, storage is necessary, store
without a charge (discharged).
7. Do not discharge the battery in devices other
than your metal detector. Unnecessary discharging
and/or an absolute discharge will reduce battery life
and may damage the battery. Unlike older rechargeable battery designs, the rechargeable battery
provided with your detector can be recharged at any
time. Regardless of whether or not it already has a
partial charge, memory will not occur.
8. White's has provided the leading edge of rechargeable battery technology with your instrument. Disregard all advice which conflicts with the
above recommendations. Care for batteries provided by other manufacturers, or with other White's
models, may vary.

Battery Life & Memory
Volatile memory temporarily holds any program
changes or settings not yet saved in a Custom
Program. Short-term or volatile memory is retained
so long as a good battery remains in the detector.
To recover volatile memory immediately squeeze
and release the TRIGGER once the detector is
turned ON. If the battery is removed all volatile
memory is lost. Long-term memory (programs
saved in Custom Programs) is automatically saved
for up to ten years regardless of whether a battery is
in the detector or not.
When using fresh batteries, the voltage will initially
check somewhere in the 10 to 14 volt area. Unlike
standard batteries, the rechargeable battery voltage
will quickly drop to between 9 and 10 volts and
plateau there for most of its life. Once the rechargeable battery voltage drops below this plateau, it will
quickly drop below a usable voltage level (eight
volts) and thus require a recharge. Low Battery will
automatically appear on the display when the
battery reaches eight volts.
Chapter 2 XLT® Batteries
Use of maximum backlight may reduce battery life
by up to 50%, depending on battery type.
Rechargeable batteries gradually deteriorate. As
they age they do not provide the life-per-charge
they did when new. This is expected, and not
grounds for replacement under warranty. Additionally, a damaged initial cell, which is caused by
over-charging with the QUICK option, is not
replaced under warranty. Only cell failure through
normal use, or a defect due to a problem with a
White's warranted XLT® charger, is covered.
Like a personal computer, there are times (such as
low battery conditions) when the microprocessor of
a metal detector becomes out of sequence with the
rest of the circuitry. This is often noted by peculiarities in the non-discrimination or pinpointing
(TRIGGER squeezed) modes. Symptoms may be
blaring or silent non-discriminate or pinpoint
modes, depth indication inaccuracies or general
abnormal operation. To correct such difficulties "reboot" by:
1. Install a good battery.
2. Turn ON wait for MAIN MENU to appear.
3. Open battery door and remove battery while
detector is still ON.
4. Wait one minute, re-install battery, turn
detector ON, and check for proper function.

Quick Start
Search Fundamentals
The loop/search coil must be in motion (sweeping from side-to-side) for this instrument to
respond to metal. Practice a smooth sweep of the
loop from side-to-side keeping the loop close to the
ground throughout the swing. Each pass of the
loop should take approximately two seconds
from right to left, two seconds to return from left
to right.
As the loop is swept over the ground, ignore the
display and concentrate on the sounds the detector
makes.
As the loop is passed over metal that is likely trash,
the sound will be inconsistent. Trash targets typically produce a shorter, sputter-type sound, that is
often broken or double in nature. Place a steel-pop
bottlecap on the ground. Pass the loop over it
several times to become familiar with this sound at
different loop sweep speeds. Note that an aluminum
twist-off bottlecap cannot be used as it is a different type of target. Also note that very old rusty
bottle caps may start reading as quarters due to the
elimination of the iron alloy through deterioration.
Once familiar with the sound typical bottle caps
produce, an operator may pass over such targets and
continue searching without consulting the display
information, saving more time for evaluating
possible good targets.
Walk forward slowly. Take small steps no greater
than half normal strides. Make sure each pass of the
loop overlaps the last by at least half the length of
the loop. Do not lift the loop at the end of each
swing. Keep it close to the ground at all times.
To become comfortable with sweeping the loop
takes some practice. Try to loosen up and find a
comfortable grip on the handle. Premature fatigue
may result from gripping the handle too tightly,
improperly adjusted rod or elbow support, and
limited body movement. Hold the handle loosely.
Adjust the rod and elbow support for comfort and
keep the elbow strap loose. Use your arm, shoulder
and even your back a little to allow a smooth even
sweep of the loop.
Now that you're sweeping the loop smoothly over the
ground, you will notice that the detector starts making
sounds (beeps). Not all sounds are good targets;
some trash targets also make the detector beep.
As the loop passes over metal that is likely a good
target, a more consistent and smooth sound will be
heard. A good target typically produces a longer,
more solid sound. Place a quarter on the ground and
sweep the loop over it several times to become
familiar with the sound of a good target.
Why Air/Ground Balance?
When the display prompts you to, AIR BALANCE by
holding the loop at waist level and press ENTER. The
XLT®'s circuits are being prepared for ground balancing by measuring temperature and other variables that
affect electronic circuits. The XLT® "beeps" and you
lower the search coil to the distance above the ground
that you will be searching. Press ENTER to have the
XLT® "cancel/track out" or GROUND BALANCE
the ground mineralization. The XLT® then automatically "tracks out" the varying mineralization as you
continue to search.

1. V.D.I. Visual Discrimination Indication
("target reference number")
In the upper left hand-side of the display there is a
V.D.I. number that corresponds to the V.D.I.
SCALE painted on the top right-hand side of the
control box. It also corresponds to the Discriminate
Edit feature allowing you to reject or accept targets
based on their V.D.I. reference number. There are
"+" numbers for non-ferrous (not of iron) targets,
and "-" numbers for ferrous (iron) targets. Rejected
V.D.I. numbers may not appear if the VISUAL
DISCRIMINATION feature is ON. Reasonably
consistent V.D.I. reference numbers (± five digits),
in a desirable area of the chart is a vote for digging
the target.
2. Possible Target Identities ("Probable or most
likely Target")
To the right of the V.D.I. number, possible target
identities will be represented graphically. These
graphics are called ICONS. A fairly consistent
indication of a desirable target is another vote to dig
the target. One or two possible target icons may
appear. There is significance to which icon appears
first. The first target to appear is always the most
likely, the second is another possibility slightly less
likely than the first.
3. SignaGraph™
The SignaGraph™ at the bottom of the display
provides a final vote as to whether or not the target
should be dug.
POSSIBLE T ARGET

SIGNAGRAPH
BARGRAPH
A. Sweep the loop over the target several times and
look at the SignaGraph™. The SignaGraph™
automatically clears itself (FADE RATE) so that it
doesn't fill the screen with information from past
loop sweeps. An operator has limited time to look
at the SignaGraph™. If you want to look at the
information again, sweep the loop over the target
several more times. The fading of the
SignaGraph™ information can be slowed or
speeded (FADE RATE) to operator preference.
This is completed in the PRO OPTIONS under
DISPLAY. Automatic AVERAGING and/or ACCUMULATING of SignaGraph™ information is
also available (See PRO OPTIONS).
B. Valuable targets will show up on the positive
side of the graph. The positive area of the chart is
the section located to the right of the zero.
C. Look for consistency. In ideal conditions, coins
and jewelry produce one or two bars to the right of
zero. Trash produces several bars, sometimes on
both sides of zero.
D. In less than ideal conditions, coins may produce
a wider pattern of bars. Most trash targets produce a
recognizably different pattern than valuable targets.
E. One of the most visual benefits of the
SignaGraph™ is the ability to show a smear pattern
on iron targets that often fool the other methods of
identification. An iron target will likely show
definite bars on both the negative and positive sides
of the SignaGraph™, often smearing all the way
across the entire chart. Valuable targets should not
produce such obviously wide patterns. In very bad
ground conditions, a good target may have a few
small bar segments in the negative area due to
mineralization. However, the pattern will show
mostly positive bars, in a fairly narrow tall group.

"X" THE LOOP TO "PINPOINT"
THE TARGET
Pinpointing the Target
Once the decision has been made to dig, move the
loop off to one side of the target area, squeeze and
hold the TRIGGER on the handle, and "X" the loop
over the spot where you believe the target to be.
Note that the TRIGGER also has a locked forward
position that accomplishes the same thing as
squeezing and holding it.

Advanced Pinpointing Techniques
1. Targets that are near the surface, because
they give a wider response, are harder to
pinpoint than deep targets. If the trigger is held
and the loop swept over the area, you may note
a shallow depth indication. Lifting the loop
slightly above the ground, releasing and resqueezing the TRIGGER and again "X" ing the
target will aid pinpointing.
2. In the Basic Adjustments, DC Sensitivity
(non-motion) directly controls the pinpointing
mode. Lower DC Sensitivity settings pinpoint
shallow targets better.
10.5"
+-12-+-+-9-+-+-6-+-+-3-+-+-0+-12-+-+-9-+-+-6-+-+-3-+-+-0
While the TRIGGER is being held, the loop doesn't
need to be moving to detect the target. The loop
may be moved slowly over the area. The display
will indicate depth in inches and will also show the
strongest reading to aid in pinpointing exactly
where to dig. The shallowest reading on the depth
display, the loudest sound coming from the speaker,
and the two bars lining up with each other, indicate
the center of the target. Don't forget to "X" the
target as pinpointing cannot be accurate unless the
target is swept from at least two different directions.
Once pinpointing is complete, release the TRIGGER, or return it to the center position.
Pinpointing takes practice. The standard loop
provided with the Spectrum® is a high-powered, 9.5
inch design. This loop's strongest traits are in the
detection depth and ground coverage areas. If
pinpointing becomes difficult or critical, an optional
smaller loop is suggested. The smaller loops have
advantages in high trash areas and pinpointing, but
will not detect as deep as the standard 9.5 inch size.
3. In the PRO OPTIONS under AUDIO, V.C.O.
(Voltage Controlled Oscillator) significantly aids
pinpointing.
4. The depth reading has two indication bars.
The top bar shows the current distance from
the target, and the bottom bar shows a memory
of the strongest reading. These two bars will be
even with each other when the loop is directly
over the center of the target.

Permission - Prior to searching and digging you
must have permission to search private property,
from the owner or caretaker.
Laws - Know the laws that apply to the area you
are going to search. Laws vary a great deal with the
City, County, State, and Country, regarding the use
of metal detectors. Be respectful of private property, public property, and the laws which govern
the use of metal detectors.
Tools - Care must be taken to dig in a way that is
friendly to the landscape. Tools and methods vary a
great deal with the area, season, and types of target
you are recovering. Check with your dealer for
recommended tools and methods for your area.
Trash - When searching, remove all trash you
come across. This not only makes your future
searches of the area more productive; it promotes
the hobby of metal detecting.
Get Involved - Your dealer knows of metal detecting clubs and organizations which promote and
protect the hobby. A club is a great way to not only
learn good detecting habits, but to gain permission
to search areas as a group as well as have organized
competition hunts.
Factory Preset Programs
Reached from the MAIN MENU, the factory
PRESET PROGRAMS give a quick start for:
Coins: general purpose settings, discriminates
(rejects) most common junk items like nails, foil,
pull tabs, and hot rocks; and responds to most coins
and large jewelry. Use in lawns, parks, and playgrounds where lots of trash rejection is desired.
Coin & Jewelry: less discrimination (less trash
rejection), desirable because of the high degree of
variance found in jewelry alloys. More digging
required. Good program for lawns, parks, and
playgrounds. Use screen more than sound.
Jewelry & Beach: similar to Coin & Jewelry, but
Pro Options are changed for salt water.
Relic: even less discrimination than Coin & Jewelry
or Jewelry & Beach, all types of metals except
small iron items like nails, and some stainless steel.
Brass, lead, aluminum, as well as copper, silver,
and gold all respond solidly. Ferrous (iron), such as
large nails, weapons, and cannon ball fragments
will also respond . Suitable for all significant targets
and separate ferrous/non-ferrous by display indications.
Prospecting: NO AUDIO DISCRIMINATION. All
metals respond with beep. But V.D.I. numbers
show only for metals that could be gold. Dig only
V.D.I. number (possibility gold) targets and avoid
iron. Targets which cause an audio response, without causing a V.D.I. number to appear on the
display, are not likely to be gold nuggets. Although
high-frequency gold-shooting detectors will respond better, this mode will offer good results for
the occasional nugget hunter by responding to
nuggets in the nine-grain and heavier category.

3. TONE (AUDIO FREQUENCY) - Selects the frequency or pitch of sound the detector produces.
4. AUDIO DISCRIMINATION - The ability to reject trash, different sounds for different types of targets.
5. SILENT SEARCH - The ability to operate without the threshold or background hum.
6. MIXED-MODE - DC non-discriminate mode, working simultaneously with AC discrimination mode.
7. A.C. SENSITIVITY - Degree instrument is responsive to signals in the discriminate (motion) modes.
8. D.C. SENSITIVITY - Degree instrument is responsive to signals in non-discriminate (non-motion) modes.
9. BACKLIGHT - Used in dark conditions to light the display improving visibility.
10. VIEWING ANGLE - Adjusts the display for low or high temperature visibility.

After you have had some field experience, you may
want to make some changes to the basic settings of
your detector. From the search mode press
MENU. At this point, the MAIN MENU will
appear on the display. Use the ARROW controls to
move the pointer to Basic Adjustments, and then
press ENTER. You may now use the ARROW
down control to scroll through the Basic Adjust-
ments.
Using the first adjustment screen (TARGET VOLUME) as an example, the screens with a graphic
control knob require you to first press ENTER
then use the ARROW up and down controls to
adjust. Note when ENTER is pressed the square
around the title moves to the setting, indicating you
are ready to make adjustments with the ARROW
controls. After adjusting press MENU and use the
ARROW controls to continue viewing / setting
other Basic Adjustments, or squeeze and release the
TRIGGER to begin searching
Adjustment screens with an on/off selection need
only for you to press ENTER to change setting.
Pressing ENTER again changes back to the original
setting.

Basic Adjustments
More Basics
All the MENU items are tied together so that the
ARROW up and down controls scroll through every
adjustment screen. If you continue to press the
ARROW down you can go beyond the last BASIC
ADJUSTMENT (View Angle) and into the PRO
OPTIONS. If the ARROW up control is pressed
after VOLUME, you will be scrolling backwards
through the options starting with the end of the
Preset Programs, then the MAIN MENU, then the
end of the PRO OPTIONS.
An important feature of the ARROW controls; If a
BASIC ADJUSTMENT has been made (for example Volume) and the trigger has been squeezed
and released to return to a search mode, you can
return to the volume adjustment simply by pressing
either of the ARROW controls. This shortcut
returns to the last adjustment that was made thereby
allowing an operator to switch directly from a
search mode to the adjustment currently being fine
tuned. This feature is desirable as you start using
BASIC ADJUSTMENTS or PRO OPTIONS that
are located further down the menu listings, or any
adjustment that may require some trial and error to
find the appropriate setting.
If care is taken to use a desired adjustment screen
last (just prior to squeezing and releasing the TRIGGER for a search mode), Custom Programs (such as
a competition hunt program) can use this ARROW
RETURN feature to allow quick easy access to the
most used feature (Transmit Frequency). Use that
feature (adjustment screen) last, just prior to
squeezing and releasing the TRIGGER for searching. Then during searching, press either ARROW to
return directly to that adjustment screen.
"Hot Key" Shortcuts
"HOT KEYS" will save time as they allow easy
access, from the search mode, to the most needed
adjustments. They are painted on the bottom of the
control box for field reference.
COIN PROGRAM - Squeeze & release TRIGGER
after automatic battery check.
SCROLL OPTION - After battery check, use
ARROWS to scroll all the current settings / menus.
AIR/GROUND BALANCE - In search mode,
press ENTER to re-Air/Ground Balance.
GROUND BALANCE ONLY - While searching,
hold the TRIGGER and press ENTER.
BATTERY CHECK - While searching, hold the
TRIGGER and press ARROW down. Sqeeze and
release TRIGGER to return to searching.
REVERSE DISPLAY - While searching, hold the
TRIGGER and press ARROW DOWN. Press
ARROWs for light/dark background. Light or dark
background will not change battery life. It will
make the display easier for some to read, particularly in certain light conditions. It will work in
combination with backlight. Reversed display is
only accessible through the "HOT KEYS".
BACKLIGHT - In search mode, hold TRIGGER
and press MENU. Release TRIGGER, press
ARROWS to set.
VIEW ANGLE - While searching, hold the TRIGGER and press ARROW up. Release TRIGGER,
press ARROWS to set.
