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. 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 receiver.

Siemens Schweiz AG

A6V11646020_en--_b

Smart Infrastructure

2020-07-10

●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. 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 Caution: Changes or modifications not expressly approved by Siemens Switzerland

Ltd. could void the user’s authority to operate the equipment. United States representative

https://new.siemens.com/us/en/products/buildingtechnologies/home.html

Industry Canada statement

This device complies with ISED’s licence-exempt RSSs. Operation is subject to the following

two conditions:

1. This device may not cause interference, and

2. this device must accept any interference received, including interference that may cause

undesired operation.

Radio frequency radiation exposure Information for USA and Canada

This equipment complies with FCC and IC radiation exposure limits set forth for an

uncontrolled environment.

This equipment should be installed and operated with a minimum distance of 20 cm (8 in)

between the radiator and your body.

This transmitter must not be co-located or operated in conjunction with any other antenna or

transmitter.
