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.
Generally, a wall clock is a fixed point. If the wall is soft, you can directly use cement nails to fix it. If the wall is hard, you can use an electric hammer to make an eye. Use 6 bricks to have a small eye, and then put it inside. Just screw a screw on…
There are generally three types of clocks and clocks, one is a plastic wall clock, the other is a metal wall clock, and the other is a frameless wall clock. The first two types of wall clocks require the outer frame of the wall clock to be removed before the clock’s hands can be further…
The volume of the electronic wall clock movement is universal, that is, there are some pointer holes that are a bit deviated. If you don’t change the pointer, this must be noted. In addition, there are two types of electronic wall clock movements, silent and old-fashioned.
Click the on/of (function key) button, select the time you want to adjust and the date to make it flash bright and dark, click the triangle symbol button (△ is to increase ▽ is to decrease) to adjust, each click increases or decreases One digit value. After adjustment, press the function key again to skip…
There are three main purposes for choosing a wall clock: 1. Look at the time. Feature. The choice of this type of wall clock should have clear fonts, clear hour and minute hands. Meeting rooms, stations, and other public places. There are some additional functions, such as temperature and humidity, more accurate radio waves, perpetual…
The rated voltage of the rechargeable battery is 1.2V, and the rated voltage of the ordinary battery is 1.5V. The wall clock is designed according to 1.5V of ordinary battery when it is designed. When the voltage of the battery drops to about 1.2V, the wall clock stops due to insufficient voltage. But compared to…
The reason for the slowness is generally caused by the wear between the gears. In addition, the wall clock will slow down as the battery power is insufficient, and this slowness is generally imperceptible. If it is noticeable, it is time to change the battery or wall clock.
An electronic clock is a timing device that displays “hours”, “minutes” and “seconds” in the human visual organs. Its timing period is 24 hours, the full-scale display is 23:59:59, and it has the function of correcting the time and reporting the time. Therefore, a basic digital clock circuit is mainly composed of decoding display, “hour”,…
Time setting: A——Date and time setting/moving B——Hourly alarm switch/increase C—— fixed alarm setting/mobile D——Water bird call adjustment (Take the setting of 10:38 AM on May 24, 2004, as an example) Press “A” key, “Year” flashes, Press the “B” key to set it to “2004”; Press the “A” key again, “Month” flashes, press “B” to set…
The electronic clock is a collective term; A quartz clock is a category of the electronic clock; The current electronic clocks are all quartz clocks. Quartz clocks rely on the natural oscillation of quartz crystals to maintain the accuracy of electronic clocks.
