An apparatus and a method for scanning neighbor networks in a mobile terminal are provided. In the method, the strength of a signal received from a serving station is measured. Whether to scan at least one neighbor network is determined with consideration of the strength of the signal. When it is determined to scan at least one neighbor network, the terminal switches to a power save mode, an at least one channel of the at least one neighbor network is scanned during an operation of the power save mode.

A locking apparatus for locking a magazine configured to receive a printed circuit board (PCB) may include an actuator, a rotating block, and a locking member. The actuator may be installed on the magazine. The rotating block may be connected to the actuator. The rotating block may be rotated about a vertical axis. The locking member may be rotatably connected to the magazine about the vertical axis. The locking member may be selectively combined with the rotating block to block a front face of the magazine, thereby preventing breakaway of the PCB from the magazine.
