PURPOSE:To easily set up time by transmitting/receiving time information through a radio channel and setting up the time based upon the time information. CONSTITUTION:The radiotelephony system is provided with a master equipment 50 connected to a wired line 10 and the radiotelephony set 1 connected to the master equipment 50 through the radio channel 40. Each of the master equipment 50 and the radiotelephony set 1 is provided with a clock part 51 for counting up the time and a display part 52 for displaying the time. Time information is transmitted/received through the radio channel 40, and on the reception side, the time is set up based upon the received time information. Since it is unnecessary to memorize how to set up the time of both the master equipment 50 and the radiotelephony set 1, the time can easily be set up. |
