XK98-AType AC/DC dual-purpose electronic quartz timer

operation instructions

1、 Overview and purpose:

XK98-AThe dual-purpose AC/DC electronic quartz timer is composed of an electronic quartz clock, transistor, voltage regulator circuit, and integrated music timing circuit, which can accurately predict the time1Every minute within the hour, it can be used as a substitute for a regular clock in daily life. It has the characteristics of low price, light weight, accurate timekeeping, and popular timekeeping tunes, and is suitable for scientific research, medical treatment, and occasions that require timing.

2、 Main technical indicators:

3、 Usage:

1.When using AC power, insert the power cord plug into a 220V AC socket, the indicator light will turn on, and the timer will start working. When using DC power (4.5V), open the back cover battery cover and install three No. 2 batteries, paying attention to the positive and negative polarity. The spring end is negative, the indicator light will turn on, and the timer will start working
2. To synchronize, pull out the knob at the opening on the back of the instrument to align the gears. Rotate the knob to adjust the minute synchronization. Once the knob is relaxed, the timer will work normally
3. Timing: Insert the timing pin into any of the 60 holes on the panel as required. When the minute touches the pin, it will automatically report the time and play a piece of music
4. The timing clock has 12 pins for selecting 12 timing points. After the time is announced, place the pins in the small hole at the bottom left of the instrument.

4、 Attention:

1.When using batteries, pay attention to the positive and negative polarity of the battery.

2.The pins should be firmly inserted to prevent poor contact from causing time or music failure.
When using AC power, the battery does not need to be removed, but when using AC power for a long time, the battery should be removed to prevent the battery liquid from flowing out and damaging the instrument
4. The timer should avoid severe vibrations and should not work in environments that are excessively humid or have strong magnetic fields.

5、 Immediately attached
