Frequently asked questions???

Q: Why are digital clocks more reliable than analog clocks?

A: Digital clocks have no moving parts to wear out.  However LED technology will reach its, "Half Life", expectancy after 100,000 hours of use, or about 11.4 years.  This means the digits will begin to dim somewhat.. That's why we have field replaceable digits, (or LED cubes).

Q: What are master clocks?

A: Master clocks are the central time keeping unit which is wired to all the clocks in your facility. LED digital clocks are updated every minute, for a, "Hyper-accurate", time keeping system.
