Recommended separation distances
The product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
product can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the product as recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated using the
equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE: 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 instruction, 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 interference by 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 dealer or an experienced radio/TV technician for help.
Electromagnetic emissions compliance
Electromagnetic environment - guidance
The product uses RF energy only for its internal function. Therefore, its RF emissions
are very low and are not likely to cause any interference in nearby electronic
Class B
The product is suitable for use in all establishments, including domestic
establishments and those directly connected to the public low-voltage power supply
network that supplies buildings used for domestic purposes.
