A method of manually setting a channel within a frequency range. The method comprises the following steps. A start frequency and a surf direction are set, and then surf channels. When a target channel is found or a pause instruction is received, surfing pauses. An auto naming function is executed to obtain a channel name of the target channel. A user determines whether to keep the channel name in a channel list. Surfing is repeated until the entire frequency range is searched or a stop instruction is received.
