WARNING:
While the laser tool is in operation,
be careful not to expose your eyes
to the emitting laser beam (red light
source). Exposure to a laser beam
for an extended time period may be
hazardous to your eyes. Do not look
into the beam with optical aids.
WARNING: To reduce the risk of
injury, user must read the Product User
manual, Laser Safety manual, and
Battery Safety information.

FCC Statement
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. This device is a portable unit.
The exclusion threshold is 0.887<3. 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 the receiver.
- Connect the equipment into an outlet on
a different circuit (not the circuit to which the
receiver is connected).
- Consult the dealer or an experienced radio/
TV technician for help.
Canada, Industry Canada (IC) Notices
Class B digital circuitry of this device complies
with Canadian ICES-003. 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 interference, and (2) this device
must accept any interference, including
interference that may cause undesired
operation of the device.
Under Industry Canada regulations, the radio
transmitter(s) in this device 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.
Battery Safety
