Press the [down/alarm] key to enter the alarm setting mode, continue to press to select any group of A1-A8, use the [up/on] key to switch the group of alarms [on/off], time display -:– Turn off this group of alarms, if it is a number, it is a normal alarm. When all the alarms are off,…
(1) Simple and easy to use, beautiful, small, and practical.
(2) Low power consumption, low voltage, energy-saving, environmental protection, and innovation.
1. Press the “D” key to enter the alarm setting, the month digital tube position displays the alarm serial number, the serial number flashes, press the “B” or “C” key, you can select one of the settings from 1 to 4; It flashes when you press the “D” key, press the “B” or “C” key…
The electronic alarm clock is controlled by a chip. The chip is controlled by a small program called a counter. After counting, the binary numbers generated by the encoder and decoder will be transmitted to turn on the semiconductor equipment and the speaker will sound. Clockwork: A device in the engine that winds up a…
The time adjustment of the wall clock is mainly realized by the internal fine-tuning capacitor. Its function is similar to the speed adjustment needle of a mechanical clock. It is designed to eliminate the error of the resonant frequency of the quartz crystal and the influence of the distributed capacitance on the oscillation frequency. It…
1. Quartz crystal oscillator: Its function is equivalent to the balance wheel with hairspring in a mechanical clock. The function of the crystal oscillator is to make the circuit generate a stable frequency oscillation signal, which is a key component to ensure the accuracy of timekeeping. Generally speaking, the higher the frequency of the crystal…
Strike on one side and strike on the other side. The function of the clock hammer is as an energy storage device, so the clock can run for a relatively long time without being guarded. When winding up the clockwork driven by the hammer, the hammer can be lifted by pulling the rope. This will…
1. Hang on drywall to prevent moisture from entering the movement, causing a short circuit of the circuit board and corrosion of the electronic parts of the movement. 2. Do not open the back cover of the quartz clock movement arbitrarily, so as to prevent dust from entering the movement and adsorbing on the rotating…
1. Insufficient battery power of the wall clock makes it unable to move Solution: If the clock slows down and keeps moving, the battery is low and needs to be replaced. If the clock at home is slow, you may not find it immediately. It may be discovered when you stop, and you will mistakenly…
The pure mechanical clock, clockwork power. With minimal wear and tear during daily use, it is particularly durable. Then coupled with the usual maintenance of the wall clock, the more durable the wall clock will be if it is used correctly.
