WARNINGS
To ensure safe operation and service of the instrument, follow these instructions. Failure
to observe these warnings can result in serious personal injury, re, or electrical shock.
• The borescope, including the camera end, is NOT insulated. Avoid probing areas where
energized conductive elements may be present. Shut off power to nearby work areas
before starting work.
• Do NOT probe moving machinery that could catch the borescope and/or camera end, and
cause harm to the operator and the Borescope.
• NEVER completely immerse the camera in water or liquids. Do NOT use the borescope for
underwater inspections.
• Avoid probing areas where chemicals may be present.
• NOT intended for use on people or animals.
• Do NOT use near sources of heat.
• Keep steady footing at all times, following ladder safety procedures when necessary.
NOTE
• Do NOT use if the charging port or housing is damaged in any way.
• No user-serviceable parts inside. Do NOT open or attempt to repair.
• Do NOT expose to direct sunlight, open flame, heat sources, equipment that produces
heat, or extremes of environmental temperature
• The borescope body is NOT waterproof. To keep dust and other foreign items out of the
unit, keep the rubber cover over the charging port when not in use

COMPLIANCE
FCC & IC COMPLIANCE
This device complies with part 15 of the FCC RULES and Industry Canada license-exempt
RSS standard(s). 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.
NOTE: The grantee is not responsible for any changes or modifications not expressly approved
by the party responsible for compliance. Such modifications could void the user’s authority to
operate the equipment.
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.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
• Consult the dealer or an experienced radio/TV technician for help
FCC & IC
RF EXPOSURE STATEMENTS:
This transmitter must not be co‐located or operated in conjunction with any other antenna or
transmitter.
This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of
5mm between the radiator and your body or nearby persons.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna
of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada.
To reduce potential radio interference to other users, the antenna type and its gain should
be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
necessary for successful communication.

COMPLIANCE
FCC RF EXPOSURE INFORMATION (SAR)
This device meets the government's requirements for exposure to radio waves. This device is
designed and manufactured not to exceed the emission limits for exposure to radio frequency
(RF) energy set by the Federal Communications Commission of the U.S. Government.
The exposure standard for wireless devices employs a unit of measurement known as the Specific
Absorption Rate, or SAR. The SAR limit set by the FCC is 1.6 W/kg. Tests for SAR are conducted
using standard operating positions accepted by the FCC with the device transmitting at its highest
certified power level in all tested frequency bands. Although the SAR is determined at the highest
certified power level, the actual SAR level of the device while operating can be well below the
maximum value. This is because the device is designed to operate at multiple power levels so as
to use only the poser required to reach the network.
In general, the closer you are to a wireless base station antenna, the lower the power output.
While there may be differences between the SAR levels of various devices and at various
positions, they all meet the government requirement.
IC NOTICE TO CANADIAN USERS
This device complies with industry Canada license-exempt RSS standard(s). 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 of the device.
This device complies with RSS-247 of Industry Canada. Operation is subject to the condition
that this device does not cause harmful interference. This Class B digital apparatus complies
with Canadian ICES-003.
This equipment complies with IC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
of 5 mm between the radiator and your body. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter.
IC RADIATION EXPOSURE STATEMENT:
This equipment complies with IC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
5mm
between the radiator and your body.
EXPOSURE OF HUMANS TO RF FIELDS (RSS-102):
The radiated energy from the antennas connected to the wireless adapters conforms to the
IC limit of the RF exposure requirement regarding IC RSS-102, Issue 5 clause 4. SAR tests
are conducted using recommended operating positions accepted by the RSS with the device
transmitting at its highest certified power level in all tested frequency band without distance
attaching away from the body.
