The master clock is designed for the operation and time control of wireless analogue and digital clocks.
The built-in, temperature compensated quartz crystal oscillator allows great accuracy, even in the case of fluctuating ambient temperatures. For extra accuracy, an external signal receiver for different types of time signals e.g. GPS is available as option.
The master clock is equipped with automatic summer/winter time adjustment.
Range is affected by a building’s structure, number of floors and walls etc. The following may be used as guidelines:
-100-200 m without repeaters
-200-400 m with 1 repeater
-300-600 m with 2 repeaters and so forth.
