BATTERY LIFE VARIES BY USE AND SETTINGS. IC RF Exposure Information and Statement The SAR limit of Canada (C) is 1.6 W/kg averaged over one gram of tissue. Device types: (IC: 6132A-TUNE520BT) has also been tested against this SAR limit According to this standard, the highest SAR value reported during product certification for head use is 0.023 W/Kg. The device was tested for typical bodily operations where the product was kept 0 mm from the head. To maintain compliance with IC RF exposure requirements, use accessories that maintain a separation distance of 0mm between the user’s head and the back of the headset. The use of belt clips, holsters and similar accessories shall not contain metal parts in its assembly. Use of accessories that do not meet these requirements may not comply with IC RF exposure requirements and should be avoided. Head operation The device was subjected to a typical head manipulation test. In order to comply with RF exposure requirements, a minimum separation distance of 0 cm must be maintained between the user’s ear and the product (including the antenna). Head exposure that do not meet these requirements may not meet RF exposure requirements and should be avoided. Use only the supplied or approved antenna DO NOT ATTEMPT TO OPEN, SERVICE, OR DISASSEMBLE THE BATTERY | DO NOT SHORT CIRCUIT | MAY EXPLODE IF DISPOSED OF IN FIRE | RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE | DISPOSE OR RECYCLE USED BATTERIES ACCORDING TO THE INSTRUCTIONS The Bluetooth® word mark and logos are registered trademarks owned by Bluetooth SIG, Inc., and any use of such marks by HARMAN International Industries, Incorporated is under license.
