The following ALR System models have been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules:

• ALR Optima Pro DT (ALL models)
• ALR Optima Pro MT (ALL models)

These limits are designed to provide reasonable protection against harmful interference in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy, and, if not installed and used in accordance with the manufacturer's instructions, may cause interference to radio communications. There is no guarantee that interference will not occur in a particular installation. If this equipment does cause 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 problem by performing one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation 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 reseller or an experienced radio-TV technician for help.
• Use shielded I/O cables when operating this equipment.

This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions:

• This device must not cause harmful interference.
• This device must accept interference which may cause undesired operation.

To ensure this product does not contribute to interference, use shielded and properly grounded I/O cables. Do not make any changes or modifications not expressly approved by the manufacturer, or the warranty could be voided.

ALR is not responsible for any radio or television interference caused by unauthorized modification of this equipment or the substitution or attachment of connecting cable and equipment other than those specified by ALR. The correction of interference caused by such unauthorized modification, substitution, or attachment will be the responsibility of the user.

Canadian Department of Communications Compliance Statement:

This digital apparatus does not exceed the Class B limits for radio noise emissions from digital apparatus as set out in the radio interference regulations of the Canadian Department of Communications. Operation of the equipment in a residential area is likely to cause harmful interference in which the user will be required to correct the interference at his own expense.
