NOTEE:

 

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.
•  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.

Environmental 

Life cycle 10 years / Storage temperature -20 ° C to + 70 ° C / Relative humidity 5 - 85% RH
Service life - 10 years. Storage conditions: temperature from -20 ° C to + 70 ° C, humidity 5% - 85%.
If you wish to discard electronic equipment, please contact your dealer or supplier for further information.
