PURPOSE:To surely sense the arrival of a call silently by mounting removably a vibrator unit to a selective call receiver main body. CONSTITUTION:A vibrator unit 13 comprising a vibrator 15, a vibrator drive battery 14 and a switch terminal controlling the operation of the vibrator is mounted removably in a selective call receiver main body 11. Thus, when the vibrator unit 13 is mounted to the selective call receiver main body 11, a switch terminal 20 of the selective call receiver main body 11 and a switch terminal of the vibrator unit 13 are connected electrically and when a transmission signal comes, the vibrator is actuated. Thus, a call is surely sensed silently without being sensed by another party. |
