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

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.

Specific Absorption Rate (SAR) information:

This 4G LTE meets the government's requirements for exposure to radio waves. The guidelines

are based on standards that were developed by independent scientific organizations through

periodic and thorough evaluation of scientific studies. The standards include a substantial safety

margin designed to assure the safety of all persons regardless of age or health.

FCC RF Exposure Information and Statement

The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types: Smart

phone (FCC ID: YPVITALCOMUMBRA) has also been tested against this SAR limit. The

highest SAR value reported under this standard during product certification for use at the ear is

0.111W/kg and when properly worn on the body is 0.711W/kg. the Hotspot SAR value is

0.711W/kg,the simultaneous transmission SAR value is 0.244W/kg on the head and 1.043W/ kg

on the body. This device was tested for typical body-worn operations with the back of the handset

kept 10mm from the body. To maintain compliance with FCC RF exposure requirements, use

accessories that maintain a 10mm separation distance between the user's body and the back of the

handset. The use of belt clips, holsters and similar accessories should not contain metallic

components in its assembly. The use of accessories that do not satisfy these requirements may not

comply with FCC RF exposure requirements, and should be avoided.

Body-worn Operation

This device was tested for typical body-worn operations. To comply with RF exposure

requirements, a minimum separation distance of 10mm must be maintained between the user’s

body and the handset, including the antenna. Third-party belt-clips, holsters, and similar

accessories used by this device should not contain any metallic components. Body-worn

accessories that do not meet these requirements may not comply with RF exposure requirements

and should be avoided. Use only the supplied or an approved antenna.
