PROBLEM TO BE SOLVED: To provide a wireless call device having a transmitter which can be searched by eyes even if a periphery is dark by providing a lighting display part for the transmitter. SOLUTION: The transmitter 10 is formed in a size so that it can be carried. It is provided with a transmission key 11, a call number storage part, a PLL control part, a radio transmission part, an antenna, the lighting display part 16 and a control part. The transmitter is driven by a battery 30. In such a case, the lighting display part 16 is composed of the light-emitting element of LED, a transistor and a resistance element for flickering/driving the light- emitting element, for example. A part which emits light is provided by making it face the outer face of the transmitter 10. A user recognizes the position of the transmitter 10 by the intermittent lighting of the lighting display part 16 when peripheral light hardly exists and it is dark at night. |
