HIGH PRECISION LASER LEVEL laser level product instructions 2/3/5 high precision level 3D/4D level instrument Read all instruction s prior to op erating this Laser level too l Do not remove any labels fromtool. Do not stare directly at the laser beam,Class 2 laser product (520-635 nm). Do not set up laser tool at eye level or operate the tool near a reflective surface as the laser beam could be projected into your eye. Do not place the laser tool in a manner that may cause someone to unintentionally look into the laser beam. Serious eye injury may be caused. Do not operate the tool in explosive environments, i.e. in the presence of gases or flammable liquids. Keep the laser tool out of the reach of children and other untrained persons. Do not attempt to viewthe laser beamthroughoptical tools such as telescopes as serious eye injury may result. Always turn the laser tool off when not in use or left unattended for a period of time. Remove the batteries when storing the tool for an extended time (more than 2 months) Do not short any battery terminals. Do not plug in when us ing Alkaline batteries. Use the adapter that comes with the laser level ONLY. Pl ease fully charge the Li-ion battery regularly (at least once every one month is recommended) to maintain its long service life. Do not dispose batteries into fire. Do not attempt to repair or disassemble the laser tool. If unqualified persons attempt to repair this tool, warranty will be void. BEFORE YOU START Unpack ing 1. Unpack all parts and lay themon a flat, stable surface. 2. Remove all pack ing materials and shipping devices if applicable. 3. Make sure the delivery contents are complete and free of any damage. If you find that parts are missing or showdamagedo not use the product but contact your dealer. Using an incomplete or damaged product represents a hazard to people and property. 4. Ensure that you have all the accessories and tools needed for assembly and operation. This also includes suitable personal protective equipment. 2 1.

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 protec�on against harmful interference in a residen�al installa�on. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc�ons, may cause harmful interference to radio communica�ons. However, there is no guarantee that interference will not occur in a par�cular installa�on. If this equipment does cause harmful interference to radio or television recep�on, 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 separa�on 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. This device complies with part 15 of the FCC Rules. Opera�on is subject to the following two condi�ons: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired opera�on. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condi�on without restric�on.

Conducted power see the test report HK2305051731‐E, antenna gain=0.64dBi Per KDB 447498 D01, when the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine RF Exposure test exclusion. The test exclusion threshold is 0.497 which is<= 3, RF Exposure testing is not required.
