ACCESSORIES

This radio is designed to operate with the accessories supplied by CALCUTTA and included in the Standard Package.

This equipment is marked

CALCUTTA declares that the radio equipment type e360 is in compliance with Directive 2014/53/EU.
The full text of the EU declaration of conformity is available at the following internet address: http://www.caltta.com/en/download.aspx

Specific Absorption Rate (SAR)

Your mobile device is a radio transmitter and receiver. It is designed not to exceed the limits for exposure to radio waves recommended by international guidelines. These guidelines were developed by the independent scientific organization ICNIRP and include safety margins designed to assure the protection of all persons, regardless of age and health.
The guidelines use a unit of measurement known as Specific Absorption Rate or SAR. The SAR limit for mobile devices is 2 W/ kg and the highest SAR value for this device when tested 25mm front of the face is 0.160W/kg, and when tested at the body is 0.911 W/kg with 5 mm distance. As mobile devices offer a range of functions, they can be used in other positions, such as on the body as described in the user manual.
As SAR is measured utilizing the device’s highest transmitting power, the actual SAR of this device while operating is typically below that indicated above. This is due to automatic changes to the power level of the device to ensure it only uses the minimum power required to communicate with the network.

• The tests are carried out in accordance with EN 50566, EN 622092, EN 62479.
