The voltage should measure 10-28 volts in the 2.5”/24VDC model and 16-28 volt in the 4.0”/24VDCmodel.Make sure the ground wire is not touching other wires.NOTE: If you fail to follow the above instructions, the fuses can be blown.The clock is not receiving an input signal. What do I do?If interfacing with other systems, make sure that the input voltage is zero when not applying a correction signal. When taking this measurement,you must be sure that the clock is disconnected from the master clock. Also, measure both AC & DC voltage. (The current consumption needed isvery low, about 3mA, and a leakage current from the master clock can be interpreted as a continuous reset signal. If you are experiencing such aproblem, please install a bypass mechanical relay).There is data noise bleeding into the intercom line. What do I do?Clock correction data wiring should be isolated from one way audio pairs.Support
