attention to possible dangers. The safety symbols
and the explanations with them, require your
careful attention and understanding. The safety
warnings do not by themselves eliminate any
danger. The instruction or warnings they give are
not substitutes for proper accident prevention
measures.
SAFETY ALERT SYMBOL. Indicates
danger, caution or warning. May be used
in conjunction with other symbols or
pictures.
Failure to obey a safety warning can result in
serious injury to yourself or to others. Always follow
the safety precautions to reduce the risk of fire,
electric shock and personal injury.
Do not attempt to operate this tool until you have
read thoroughly and completely understood the
safety rules, etc. contained in this manual. Failure
to comply can result in accidents involving fire,
electric shock or serious personal injury. Save this
Owners Operating Manual and review it frequently
for continual safe operation and for instructing
others who may use this tool.
INTENDED USE
Your Ryobi wall detector has been designed for
domestic use only. it may be used to detect ferrous
metal (e.g. steel), non-ferrous metal (e.g. copper)
and live wires/conductors in walls, ceilings and
floors.
WARNING
To reduce the risk of injury, the user must
read and understand the operator’s
manual.
WARNING
Do not attempt to operate this tool
until you have read thoroughly and
understood completely all instructions,
safety rules etc contained in this manual.
Failure to comply may result in accidents
involving fire, electric shock or serious
personal injury. Save operator’s manual
and review frequently for continuing safe
operation, and instructing others who
may use this tool.
SAFETY INSTRUCTIONS
DO NOT TAKE ANY ACTION THAT COULD BE
DANGEROUS IF THE WALL CONTAINS A LIVE
ELECTRICAL WIRE, GAS OR WATER PIPE.
Once object is detected, always turn off the
electrical power, gas and water supplies before
drilling hole or driving nail/screw into the wall.
Failure to follow these instructions may result in
electrical shock, fire and/or serious injury.
Do not rely exclusively on the detector to locate
items behind the scanned surface. Use other
information sources to help locate items before
penetrating the surface. Such additional sources
include construction plans and visible points of
entry of pipes and wiring into walls.
Do not disassemble. Have your product serviced
by a qualified repair person using only identical
replacement parts. This will ensure that the safety
of the product is maintained.
This device is not a toy and must not reach
children’s hands. It contains hazardous objects as
well as small parts that the children could swallow.
In case a child swallows any of them, please
contact a physician immediately.
Do not leave batteries and packing material lying
around unattended; they can be dangerous for
children if they use them as toys.
In case the device is going to be unused for an
extended period of time, remove the batteries to
prevent them from draining
Expired or damaged batteries can cause
cauterization on contact with the skin. Always,
therefore, use suitable hand gloves in such cases
See that the battery is not short-circuited. Do not
throw batteries into a fire.
Do not use on a ladder or unstable support. Stable
footing on a solid surface enables better control of

OPERATION
CAUTION. Live wires may not be
detected if wires are shielded or in
conduits or behind thick walls or are
more than 40mm away from the scanned surface,
or in concrete, behind a plywood shear wall or
metallic wall covering, or if moisture is present in
the environment or on scanned surface or on the
sensor.
Prior to operating this tool, make sure the area
marked “SE SOR” in the bottom of the housing is
dry. If required, wipe dry using a dry and clean
cloth.
Environmental influences, such as humidity or
closeness to electrical devices, can influence the
measurement accuracy. Surface quality and
condition of the walls (e.g., moisture, metallic
building materials, conductive wallpaper, insulation
materials and tiles) as well as the amount, type,
size and position of the objects can lead to
inaccurate measurements.
If the tool has been subjected to an extreme
temperature change, allow the sensor to adjust to
the ambient temperature before use.
Due to uneven density of tile work on cement board
(used in kitchens, bath/wash rooms) wall sensor
may generate false indications.
Do not expose product to rain or wet conditions or
long term exposure to the sun.
Do not use in harsh environment. Use only in
temperature range -10C° - + 50C°.
To increase battery life, turn off the sensor after
each use.
TURNING THE UNIT ON AND OFF
Press and hold the On/Off button to turn on the
unit, Fig.2. Release the On/Off button to turn the
unit off.
CALIBRATING THE WALL DETECTOR
Hfld the wall detector in your hand away from any
metal objects and live wires. Quickly press the
On/Off button several times unti the metal
detection indicator light and the live wire detection
indicator light illuminate red, Fig.3. When the lights
go out the machine is ready to use.
ote: If the instrument fails to calibrate it could be
due to:
The current measured surface is too wet.
Environmental influences, such as humidity.
Instrument malfunction.
MEASUREMENT OPERATION
With the wall detector flat against the wall and the
On/Off button pressed move the instrument left or
right. When the instrument detects a metal edge,
the metal detection indicator light will change from
green to red and a beep will be heard. Mark this
point with a pencil using the marker point on the
top of the wall detector, Fig.4
Fig. 2
Fig. 3

OPERATION
Continue moving the instrument in the same
direction until the metal detection indicator light
illuminates green again. Mark this second point
with a pencil. The midpoint of these two marks is
the central location of the measured metal object.
ote: After you release the On/Off button, the unit
must be calibrated again before reuse.
DETECTING LIVE WIRES
With the wall detector flat against the wall and the
On/Off button pressed move the instrument left or
right. When the instrument detects a hot wire, the
live wire detection indicator light will illuminate red
and flash and a intermittent beep will be heard,
Fig.5. Mark this point with a pencil using the marker
point on the top of the wall detector.
Continue moving the instrument in the same
direction until the live wire detection indicator light
goes off. Mark this second point with a pencil. The
midpoint of these two marks is the central location
of the measured hot wire.
ote: Wires deeper than the detection limit from
the surface, in conduit, or behind plywood
shearwall will not be detected. Use caution under
these circumstances.
Rubbing or banging the unit on the wall may
generate static electricity and cause a false
reading.

MAINTENANCE
WARNING. Do not operate the detector
until the battery compartment cover is in
place and fastened
GENERAL MAINTENANCE
This instrument is designed to provide years of
dependable service, if the following care
instructions are performed:

RECYCLING AND DISPOSAL
GENERAL MAINTENANCE
Recycle unwanted materials instead of disposing of
them as waste. All tools, hoses and packaging
should be sorted, taken to the local recycling centre
and disposed of in an environmentally safe way.
Recycle rather than dispose of unwanted material
in landfill whenever possible. The machine must be
delivered in rigid packaging to avoid damage
during transportation. The packaging and the
machine itself are manufactured from recyclable
materials and should be disposed of accordingly.
Only dispose of electrical/electronic/battery terms
in separate collection schemes, which cater for the
recovery and recycling of materials contained
within. Your cooperation is vital to ensure the
success of these schemes and for the protection of
the environment.
Recycle packaging where facilities exist.
This symbol is known as the Crossed
out Wheelie Bin Symbol. When this
symbol is marked on a product or
battery, it means that it should not be
disposed of with your general
household waste. Some chemicals
contained within electrical/electronic products or
batteries can be harmful to health.
