Frequently Asked Questions

Q: My unit is not letting me reset FT and or not keeping time, what is wrong?

A: The memory battery is very low or dead and needs to be replaced. Battery should be replaced every two years. Replace at top of hour to have minutes close to 00:00.

 

Q: I can't set the minutes on my clock, why not?

A: On the older 811B clocks, under serial # A40000, you can only set minutes by speeding up or pausing the seconds.

 

Q: One of my digits is missing, how do I fix it?

A: The digits are field replaceable, and mounted in sockets. All 6 digits are the same and the part # is KW505F.
