Output power is ERP for Part 22 and EIRP for Part 24. This device contains functions that are not operational in U.S Territories. Filings under this FCC ID are applicable only for US operations. SAR compliance for body operating configurations is limited to the specific configurations tested under this FCC ID. For satisfying FCC RF exposure compliance requirements, near-body operations are restricted to belt-clips, holsters or similar accessories that have no metallic component in the assembly and must provide at least 1.5 cm separation between the device, including its antenna, and the user's body. End-users must be informed of the near-body operating requirements for satisfying RF exposure compliance. The highest reported SAR values for filings under this FCC ID are: 800 MHz: head 0.60 W/kg, body 1.12 W/kg; 1900 MHz: head 0.43 W/kg, body 1.08 W/kg. HAC Rating: M4/T4-2007

HC: This equipment complies with the hearing aid compatibility technical requirements of Section 20.19 of the rules.
