When implementing a new system or adding new system devices, learn about what should be considered to ensure a seamless installation.
For a system with Repeater Transmitters, always install and configure the main Transmitter first and then install the Repeater Transmitter(s).
When a clock is powered on, it automatically initializes its set up and searches for a signal to receive its time.
The scheduled search frequency varies by clock model as defined below.
When a clock has not received a valid signal/time update for three consecutive days, it displays a visual signal loss indicator; an analog clock's second hand advances and pauses continuously (stepping) and a digital clock/timer's colons flash.
The GPS Receiver needs to “see” three satellites in the sky above before it will send a time signal to the Transmitter. If the GPS Receiver has a 360° view of the sky, the process may take only 15 minutes or as many as several hours. The length of time is dependent on the location (if the unit does not have a full view of the sky, due to wall or window installations, building “shadows”, etc.) weather conditions (clear or overcast) time of day, and other similar environmental factors.
If the Transmitter is receiving its time source from the optional NTP configuration, it sends requests to the NTP server at defined intervals.
The Transmitter does not transmit time data until it has received valid time information from a time source. Once the Transmitter receives a time signal, the Transmitter sets its internal clock to the received time and displays the correct time and date. The Transmitter then begins transmission of its internal time once every second. The Transmitter continually monitors it time source connection and updates its internal clock with the time data it receives.
While using the timed broadcast schedule of a Transmitter with an external antenna, the Receiver Switch updates between 40 and 56 minutes past the hour. The actual update time varies depending on the channel number it is receiving a signal on.
If installing a Receiver Switch after the initial Transmitter 8 hour power up transmission, there are three options:
Install the Receiver Switch between 39 minutes past the hour and 6 minutes after the next hour. It will set right away.
Install the Receiver Switch at any time of the day, it will disable the output of the Repeater (Satellite) Transmitter and the green LED will remain solid until 39 minutes after the hour. At that time, the LED will begin flashing and the Transmitter connected to it will begin broadcasting.
Power cycle the Transmitter. It will then transmit for 8 hours and the Receiver Switch will update immediately on power up.
If installing a Wireless Tone Generator after the Transmitter initial 8 hour transmission, there are two options:
Install the Wireless Tone Generator between 39 minutes past the hour and 6 minutes after the next hour. It will update its time right away and begin updating its schedule information.
Power cycle the Transmitter. It will then broadcast continuously for 8 hours and the Wireless Tone Generator will update both its time and schedule information immediately on power up.
