on the unit itself as well as the safety instructions listed below.
Safety Symbols
To reduce the risk of injury and to ensure the continued safe operation of this product, the following safety
instructions and warnings are marked in this manual.
WARNING
This indicates the risk of electric shock. The presence of high voltage levels may constitute a risk of
injury or death to users and/or installers.
CAUTION
This indicates important information where failure to comply may result in safety hazards or cause
damage to this product.
Safety Instructions
• Read all instructions and cautionary marks in the manual carefully before starting the installation. Failure to
comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended use of the device. The manufacturer assumes no liability for the customer’s
failure to comply with these requirements.
• Do not attempt to repair this product; it does not contain user-serviceable parts. Repairs and internal servicing
should only be performed by authorized service personnel.
• Do not tamper with or open this product. Opening this product may result in electric shock.
• Perform all electrical installations in accordance with all applicable local electrical codes and the National
Electrical Code (NEC), ANSI/NFPA 70.
• Only qualified electrical personnel should perform the electrical installation/wiring of this product.
• Switch off the circuit breakers before installation and wirings.
• For the safety of installation, remove all conductive jewelry or equipment during the installation or service of the
device parts, connector and/or wiring.
• Do not stand on a wet location while doing installation and wirings. Enclose the outer covering well before
switch on the circuit breakers.
FCC Compliance
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. 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,
you are 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 circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compliance may void the user’s
authority to operate the equipment.
