The main functions of the CJ-3200 type tower clock are as follows:
I. Timing: Fully computer controlled and managed, with screen display, automatic two-hand operation, and the slave-master clock system adopts closed-loop control to maintain the synchronization of the slave-master clocks and the Beijing time.
II. GPS satellite time correction: Connected with the computer center and satellite signal receiving equipment, the separated standard time is compared and corrected with the master clock time to ensure that the operation of the tower clock is synchronized with the standard time, achieving no accumulated error.
III. Time announcement: Multimedia time announcement is adopted, with high-fidelity announcement effects.
Announcement methods include:
① Big Ben melody with bell sounds (three different timbres) ② East Is Red melody bell sounds (four different timbres) ③ East Is Red melody with voice announcement ④ Bell sounds (eight different timbres) ⑤ China, China, the bright red sun never sets melody (one) ⑥ Step into a new era melody ⑦ Stop broadcasting; multimedia time announcement requires a computer.

After power is restored, the slave clock can automatically track the standard time without the need for manual adjustment. The user can also specify a time for the clock to continue running during a power outage.
VI. Fault self-diagnosis function: When a fault occurs in a part of the system, the controller automatically diagnoses the fault and transmits the fault phenomenon information to the control center, which immediately displays the fault location and indicates how to eliminate the fault. This function can only be realized with a computer.
