COMPLIANCE
FCC Class B Notice
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO
THE FOLLOWING TWO CONDITIONS:
(1) THIS DEVICE MAY NOT CAUSE HARMFUL INTERFERENCE, AND
(2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING
INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION.
Class B Devices
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency
energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Consult the dealer or an experienced radio/ TV technician for help.
ICES-003 Class B Notice
This Class B digital device complies with Canadian ICES-003(B)/NMB-3(B).
EU Declaration of Conformity
Hereby, Fisher Research Labs ®, declares that the XLT-100 Compact Acoustic Leak
Detector complies with the EMC standards under Directive 2014/30/EU.

BATTERIES
The XLT-100 uses two AA
batteries. Operating life using
2 AA alkaline batteries is
approximately 12-15 hours.
When charge indicator
becomes low, batteries should
be replaced. The XLT-100 will
automatically turn o if the
battery voltage becomes too
low. To replace old batteries,
use a coin or at-head screw
driver to turn the battery cap
counterclockwise until it comes
o. The XLT-100 has special
foam inserts in the battery
compartment; these inserts may
prevent batteries from sliding
out. If this happens, gently tap
the bottom of the XLT-100 on
a at surface, and batteries will
dislodge.
EXTENSION RODS
Included extension rods (2-13”)
May be used in place of standard
probe tip when longer reach for
contact with facility is required.
Extension Rods can also be
inserted into probe holes over
water line in turf areas.
HAND NOISE
Like all accelerometers,
contact microphones, ground
microphones and stethoscopes,
hand movement on the surface
of the housing will induce
vibrations into the sensor which
you will hear as a rubbing noise.
To avoid this, hold housing
securely and do not move hand
over the surface while listening.
SOME POTENTIAL
HAZARDS
As the sensor and extension rods
are “pointed”; caution should
be used when operating or
transporting the device.
Always select the lowest volume
setting that is appropriate for
each leak sound analysis.
It is recommended to set device
to MUTE until positioned to
sample for leak noise, then set to
OFF or MUTE immediately after
each sampling.
For safety reasons, do not
use this device near trac
or where other dangers are
present. This device is to be used
with interconnecting cables/
headphone cables shorter than
three meters.
Fisher Research Laboratory does
not warrant suitability to specic
use. Fisher Research Laboratory
shall in no event be liable for any
direct, incidental, consequential
or indirect damages.
