  1. GPS precise timing: The GPS synchronous timing system has high timing accuracy, wide range, high reliability, and is not affected by various interferences all day long.

  2. NTP network timing: First, reset the correct time of the LED electronic clock, insert it into the network cable, and wait for a few seconds to complete the timing. The internal accuracy of NTP network timing reaches ns level, and the network timing accuracy can reach 1-50 milliseconds in different network environments

  3. CDMA telecommunications time calibration: The CDMA electronic clock can automatically calibrate the time directly through the telecommunications 2G or 3G network.
