Can the digital clock be used as an independent clock? No, the V-D2425B and V-D2440B digital clocks require Valcom 2-wire digital correction. Some clocks require a 9 volt battery backup for timekeeping. What happens to the V-D2524B or V-D2440B if a power failure occurs? Upon restoration of power, the clock immediately receives a correction signal from the master clock and resets itself to display the correct time.
Valcom, Inc. +1 540-563-2000 P. 5614 Hollins Road +1 540-362-9800 F. Roanoke, VA 24019 www.valcom.com Troubleshooting The clock is not running. What do I do? Measure the input voltage to the clock. The voltage should measure 10-28 volts in the 2.5”/24VDC model and 16-28 volt in the 4.0”/24VDC model.
