LIDAR-LITE V3HP
OPERATION MANUAL AND
TECHNICAL SPECIFICATIONS
Laser Safety
This device requires no regular maintenance. In the event that
the device becomes damaged or is inoperable, repair or service
must be handled by authorized, factory-trained technicians only.
Attempting to repair or service the unit on your own can result in
direct exposure to laser radiation and the risk of permanent eye
damage. For repair or service, contact your dealer or Garmin
for more information.
This device has a protective housing which, when in place,
prevents human access to laser radiation in excess of the
accessible emission limit (AEL) for Class 1 laser products. This
device should not be modified or operated without its housing or
optics. Operating this device without a housing and optics, or
operating this device with a modified housing or optics that
expose the laser source, may result in direct exposure to laser
radiation and the risk of permanent eye damage. Removal or
modification of the diffuser in front of the laser optic may result in
the risk of permanent eye damage.
This device emits laser radiation. Use of controls or adjustments
or performance of procedures other than those specified herein
may result in hazardous radiation exposure.
This laser product is designated Class 1 during all procedures of
operation. When the ranging feature of the device is activated, a
laser emitter of a ranging module may emit laser radiation and
the device should not be aimed toward anyone. Avoid looking
toward the laser emitter or into the laser radiation (beam) when
operating the device. It is advisable to turn off the ranging
module when it is not in use. This device must be used only
according to the directions and procedures described in this
documentation.
Do not leave this device within the reach of children.
CLASS 1 LASER PRODUCT
Classified EN/IEC 60825-1 2014
This product is in conformity with performance standards for
laser products under 21 CFR 1040, except with respect to those
characteristics authorized by a variance number.

Important:
The bare wire portion of the
wiring harness is not water
resistant, and can act as a path
for water to enter the device. All
bare-wire connections must
either be made in a water-tight
location or properly sealed.
Water may enter under the
transmitting lens. This could
affect performance, but will not
affect the IEC 60529 IPX7
water rating.
