1. A method for operating a pointing device comprising a radio signal transceiver, an input portion including a power-on button, and a sensor portion including a gyro sensor and an acceleration sensor, the method comprising:
- receiving, at the pointing device, a power on input from the power-on button;
transmitting at least one infrared (IR) signal to a television in response to the power on input;
receiving, at the pointing device, a signal from the television, wherein the signal is received from the television in response to the television powering on based on the at least one infrared (IR) signal, and the signal is received through a radio frequency (RF) communication standard;
transmitting a pairing request signal in response to the received signal from the television;
receiving information from the television, the received information including information of pairing-available frequency channel of a plurality of frequency channels;
selecting at least one of a frequency channel as a pairing frequency channel based on the received information from the television;
operating the pointing device in an RF mode after pairing between the pointing device and the television based on the selected frequency channel;
receiving signals sensed from the gyro sensor and the acceleration sensor; and
transmitting a RF signal to the television using the selected frequency channel, wherein the RF signal includes information regarding movement of the pointing device corresponding to the signals received from the gyro sensor and the acceleration sensor.

Abstract
A method for pairing and operating a multi-mode pointing device is provided. A pointing device may be automatically paired with an image display device. A pairing request signal may be transmitted on a prescribed frequency channel, and a signal may be received indicating information of a plurality of frequency channels. One of the frequency channels may be selected as a pairing frequency channel for operating in a radio frequency mode.
