Selective calling/receiving device |
摘要 |
The result of detection performed by a receiving electric-field level detection circuit 8 and the result of detection performed by an automatic gain setting circuit 9 are fed back to a timing signal generation circuit 10 which controls a pre-heat time of a selective calling/receiving device. As a result, the pre-heat time can be changed according to the state of propagation of radio waves, and hence the life of battery of the calling/receiving device can be increased.
