User Safety
WARNING:
Carefully read the Safety Instructions and 
Product Manual before using this product. The 
person responsible for the product must ensure 
that all users understand and adhere to these 
instructions.
WARNING:
The following label information is placed on your 
laser tool to inform you of the laser class for your 
convenience and safety.
DW099S
FCC ID: 2ADA6DW099S
IC: 12409A-DW099S
DW099E
The DW099E and DW099S tools emit a visible laser 
beam, as shown in Figure A#1. The laser beam emitted 
is Laser Class 2 per IEC 60825-1 and complies with 21 
CFR 1040.10 and 1040.11 except for deviations pursuant 
to Laser Notice No. 50, dated June 24, 2007.
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 Compliance
This device complies with Part 15 of the FCC Rules. 
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.
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.
