TIME OF DAY

The time of day is maintained by a real time clock internal to the PZM. This time of day is broadcast as a Class 2 message over the serial data bus. The radio receives this data and displays the data on the front panel. The time of day is changed with the HR or MN button on the front of the radio. The radio translates the button actuations. The radio then sends a Class 2 message to the PZM requesting a change in the time. The radio does not maintain the time.
