The OneVue Sync 72MHz system provides synchronized time over the 72MHz wireless radio frequency. The main Transmitter transmits (broadcasts) a time signal that is received by the system Clocks and Repeater Transmitters. Both the Transmitters and Clocks have a time sync schedule that varies by model.
The following details the Transmitter and Clock schedules.
If installing devices after a Transmitter's initial 8 hour power-on, there are three options to ensure a device receives a time update during installation.
Install devices between 39 minutes past the hour and 6 minutes after the next hour and devices receive a time update when powered on. For example, between 9:40 AM and 10:05 AM.
Install the devices at any time of the day. Devices will receive a time update at the next 39 minutes after the hour.
Power-cycle the Transmitter. It will then transmit for 8 consecutive hours and devices receive a time update when powered on.
Each clock model has a schedule, which is when the clock's receiver turns on to search for time signal from a Transmitter. When a clock receives a time signal, it synchronizes its time to the time received from a Transmitter. When a clock is first-powered on or is powered on and off, it automatically searches for a time signal to set its time.
Analog Clocks: at six pre-scheduled times a day, at 2:01 AM/PM, 6:01 AM/PM, and 10:01 AM/PM clock time (not the actual time of the day),
Digital Clocks/Timers: every 10 minutes on the 5's (5, 15, 25, 35, 45, 55 minutes) of the hour.
When a clock has not received a valid time signal from a Transmitter for three consecutive days, it displays a visual signal loss indicator. Although the clock may display the correct time, it's not synchronized and its time may drift.
Analog Clock: its second-hand advances and pauses continuously (stepping)
Digital Clock/Timer: its colons flash (between the time and hour)
