PROBLEM TO BE SOLVED: To reduce power consumption by making only a visible luminous body light up depending on the floating state of the electronic apparatus while the electronic apparatus is submerged.SOLUTION: A transceiver comprises: a front submergence detection unit 600A and a rear submergence detection unit 600B for detecting the submergence of itself and also being picked up; a front LED 118A and a rear LED 117B provided inside an enclosure 111; a front lighting circuit 500A and a rear lighting circuit 500B for turning on the front LED 118A and the rear LED 117B respectively; and a control unit 200 for turning on the front LED 118A or the rear LED 117B between time the electronic apparatus is submerged and time it is then picked up. The front submergence detection unit 600A detects submergence at the submergence posture of the front being upward and has the front LED 118A turned on and the rear submergence detection unit 600B detects submergence at the submergence posture of the rear being upward and has the rear LED 117B turned on.SELECTED DRAWING: Figure 2 |
