Verizon LG-TM510 manual Subject

In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg (W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin of safety to give additional protection for the public and to account for any variations in measurements.

SUBJECT

The LG-TM510 phone has been designed to operate on the latest digital mobile communication technology, Code Division Multiple Access (CDMA). CDMA digital technology has greatly enhanced voice clarity and can provide a variety of advanced features. Currently, CDMA mobile communication technology has been commercially used in Cellular and Personal Communication Service (PCS).

The difference between them is the operating frequency spectrum. Cellular uses 800 MHz and PCS uses 1.9 GHz. The LG-TM510phone can operate on both frequencies, so it is referred to as a dual-band phone. Also, the LG-TM510phone works on Advanced Mobile Phone Service (AMPS). We call it a tri-mode phone. If one of the Cellular, PCS, and AMPS base stations is located nearby, the call fail rate of the tri-mode phone is less than a dual-band phone or a single-band phone.

CDMA technology adopts DSSS (Direct Sequence Spread Spectrum.) DSSS enables the phone to keep communication discreet and allows one frequency channel to be used by multiple users in the same specific area, resulting in increased capacity 10 times more compared to the analog mode currently used. Soft/Softer Handoff, Hard Handoff, and Dynamic RF power control technologies are combined into this phone to reduce interruptions in a middle of a call.
