1) The digital clock at the back has a two core power cable. Plug the cable into the 230v AC socket and switch on the supply. The display of the clock will get ON.
2) The digital clock will first do the segment test, to show the segments are working fine.
3) The digital clock will then display the time working in its RTC memory, till it receives the signal from the master clock.
4) The digital clock, till it receives the signal from the master clock, the indictor on top corner of the Hours Segment will glow on. Once the Digital Clock receives the signals from the Master Clock, the indictor on top corner of the Hours Segment will get switched off. And the Digital Clocks gets synchronized with the Master clock
5) Initially for the first time the clock will take 3 to 4 minutes to synchronize with the Master Clock if the signal strength is strong. Sometimes if the signal strength of the master clock is week in a particular area, then the Digital clock may take little time in synchronizing with the master clock. Once the digital clock synchronizes then it keeps synchronized.
6) In Case of power failure at the master clock, the Digital clock time will work on the internal RTC. The Internal RTC has a 3v lithium battery to store the time in it memory.
7) If the digital clock has not received the signal from the master for at least 30 minutes, the indictor on top corner of the Hours Segment will glow on. Once the Digital Clock receives the signals from the Master Clock, the indictor on top corner of the Hours Segment will get switched off. And the Digital Clocks gets synchronized with the Master clock
8) In Case of power failure at the Digital clock, the Digital clock time will work on its internal RTC, without displaying the Time, as the Internal RTC has a 3v lithium battery. And will display the RTC Time on the Display when the power is restored. The indictor on top corner of the Hours Segment will glow on. Once the Digital Clock receives the signals from the Master Clock, the indictor on top corner of the Hours Segment will get switched off. And the Digital Clocks gets synchronized with the Master clock.
Slave Digital Clock
Model No. – 2SSC2v
Make – Bethel
Each clock includes a 433 MHz receiver. The clocks are configured in the field to receive the data from the master clock and update the accurate time. These clocks can cover large areas indoors (up to 500 meter radius). The clocks incorporate frequency hopping / spread spectrum (FH/SS) technology coupled with DES data encryption to be sure no one tampers with time transmissions, and are free from interference.
