Safety Instructions
Installation Safety Warnings
Read and follow the instructions and precautions in this guide and all documents referenced in this
guide when installing this device. Always refer to the vehicle manufacturer’s service manual for proper
installation and wiring of any aftermarket devices, including the SF-Series device. Failure to do so may
result in property damage and/or personal injury.
WARNING: Park the vehicle on a level surface before beginning any maintenance or installation.
Block the wheels to prevent the vehicle from moving. Never work under a vehicle supported only by
jacks as jacks can slip and fall over.
WARNING: All wires that carry electrical current to the Lytx device(s) must be fused. Failure to fuse
the power, ground, and ignition wires can lead to serious personal injury and/or property damage. If any
wires or cables containing fuses/fuse boxes need to be cut or otherwise shortened, always be certain to
replace such fuses/fuse boxes or install new ones.
WARNING: Wire Protection: Take all necessary measures to protect all wire runs through a metal
surface with a grommet or other device and all wire runs outside the vehicle cab with a loom. Always
protect against wire fatigue and harness abrasion by properly attaching wires at closely spaced
intervals, while avoiding contact with sharp edges or doing anything else that might result in exposed
wires. All wires should be secured with tie wraps at least every one foot (30 cm/300 mm) or less. Do not
over-tighten any tie wraps.
EXPLOSION HAZARD: Do not disconnect equipment unless power has been removed and the area is
known to be non-hazardous.
WARNING: Substituting or supplementing components may impair suitability and performance. If you
are missing any components contact Lytx Technical Support Center at 925.732.4246 or email
[email protected].
WARNING: Wear safe eye protection to prevent serious eye injury when you perform vehicle
maintenance or service.
Driver Safety Warnings
WARNING: In order to reduce the potential danger of injuries, the driver and front passenger must
always be correctly seated with seat belts correctly fastened when operating the vehicle.
DISCLAIMER: The Lytx Event Recorder is a driver aid only, not a substitute for a safe, conscientious
driver. The Lytx Event Recorder cannot compensate for a driver who is distracted, inattentive or impaired
by fatigue, drugs or alcohol. Whether or not the Lytx Event Recorder is in use, it is always the
responsibility of the driver to take appropriate corrective action. Never wait for the device to provide a
warning before taking measures to avoid an accident. Failure to do so can result in serious personal
injury or death or severe property damage.

(North America Edition)
Always, it is the driver’s responsibility to:
•Use safe driving techniques
•Exercise proper judgment
•Maintain a safe speed and distance between vehicles
•Take measures to avoid an accident
•Comply with all applicable laws and regulations
WARNING: In certain conditions, including inclement weather, low visibility, certain road conditions
(including poor lane markings, construction zones, dirt roads, heavy or complicated traffic, and curvy and
winding roads), the Lytx Event Recorder may have limited to no functionality. The Lytx Event Recorder
may not detect certain objects such as motorcyclists, bicyclists or pedestrians even in the most ideal
conditions. Always keep the lens and view of the Lytx Event Recorder unobstructed and properly
calibrated so as not to inhibit function. Driving in certain conditions or any interference with the Lytx
Event Recorder can result in false, few or no warnings. The driver must always monitor traffic and
surroundings and take measures to avoid an accident; failure to do so can result in serious personal
injury or death or severe property damage.
WARNING: If the Lytx Event Recorder is not functioning properly at any time, please contact your
supervisor and have the device inspected immediately to correct the issue. Whether or not the Lytx Event
Recorder is functioning, it is the driver’s responsibility to maintain vehicle control; failure to do so can
result in serious personal injury or death or severe property damage.
CAUTION: While cleaning the device or the vehicle cab, do not apply compressed air or cleaning solutions
(such as Windex) to the Lytx device. Usage of these products may cause damage to the device.
WARNING: The optional livestream feature may have an approximate delay of 10 seconds.
Livestream should never be used to assist the driver in operating the vehicle. The driver is
responsible for the safe operation of the vehicle at all times and must always take measures to avoid
a collision.
Adherence to Applicable Local, State and Federal Laws
WARNING: Some countries/regions/jurisdictions have adopted, or may in the future adopt, laws that
prohibit objects from being mounted on a vehicle’s windshield or other locations in a vehicle. Always
refer to any applicable laws that concern mounting devices on vehicle windshields before choosing a
mounting location. You are responsible for complying with such laws, as Lytx, Inc. does not accept
responsibility for your failure to do so.
