1. Add cleaning fluid

在清洗槽內加入清水，并根據污垢性質添加適量的清洗劑。液體不宜太滿或太少，能夠浸沒清洗物即可。如需開啟加熱功能，液面高度則不可低于內槽高度2/3。

Add clean water into the cleaning tank and add an appropriate amount of cleaning agent according to the nature of dirt. The liquid should not be too full or too little. It can immerse the cleaning material. If the heating function needs to be turned on, the liquid level shall not be lower than 2 / 3 of the height of the inner tank.

2、放置清洗物

2. Place cleaning materials

先將清洗物放置在清洗籃，而后同清洗籃一同放入清洗槽內，盡量不要直接將清洗物放置在清洗槽。

First place the cleaning materials in the cleaning basket, and then put them into the cleaning tank together with the cleaning basket. Try not to directly place the cleaning materials in the cleaning tank.

3、開機

3. Power on

正確連接電源插頭，確保所供電源可靠接地。打開機器背面電源總開關（”0”表示關閉，＂-＂表示打開），開啟后機器處于通電狀態。

Connect the power plug correctly to ensure the reliable grounding of the power supply. Turn on the main power switch on the back of the machine ("0" means off, "-" means on), and the machine will be powered on after it is turned on.

3.1 設置時間，啟動超聲

3.1 set the time and start the ultrasound

開機后時間顯示為上次設置時間，按“設置”鍵一次，分鐘顯示數值閃爍，調節旋鈕即可設置分鐘。再按“設置”鍵一次，秒鐘顯示數值閃爍，調節旋鈕即可設置秒鐘。調節分鐘、秒鐘數值后，停止5秒時間設置完成。按“超聲”鍵一次，啟動超聲波，再按一次，超聲波暫停。

After power on, the time is displayed as the last set time. Press the "set" key once, and the displayed value of minute flashes. Adjust the knob to set the minute. Press the "setting" key again, the displayed value will flash, and the adjustment knob can set for seconds. After adjusting the values of minutes and seconds, stop the 5-second time setting. Press the "ultrasonic" key once to start the ultrasonic. Press it again to pause the ultrasonic.

3.2  設置溫度

3.2 setting temperature

開機后溫度顯示為上次設置溫度，連續按“設置鍵"，直至溫度顯示數值為閃爍狀態，調節旋鈕至所需溫度后停止，5秒鐘后溫度設置完成。按“加熱”鍵一次，啟動加熱功能，再按一次暫停加熱，紅色溫度圖標常亮。

After startup, the temperature is displayed as the last set temperature. Press the "set key" continuously until the temperature display value is flashing. Adjust the knob to the required temperature and then stop. After 5 seconds, the temperature setting is completed. Press the "heating" key once to start the heating function, press it again to pause heating, and the red temperature icon is always on.

4、頻率切換、脫氣功能

4. Frequency switching and degassing function

4.1 頻率切換（僅限D系列雙頻機型）

4.1 frequency switching (only for D-series dual band models)

開機后頻率顯示為上次設置頻率，按“頻率”鍵一次即可切換頻率。例如：28或45、45或80之間互相切換，具體需看使用何種機型。

After power on, the frequency is displayed as the last set frequency. Press the "frequency" key once to switch the frequency. For example: switch between 28 or 45, 45 or 80, depending on which model is used.

4.2 脫氣功能（僅限D系列單頻機型）

4.2 degassing function (only for D-series single frequency models)

按“脫氣”鍵一次，啟動脫氣功能，儀器將以工作9秒停6秒的工作方式循環進行。此功能可將清洗時產生的空氣排出，提升清洗效果。

Press the "degassing" key once to start the degassing function, and the instrument will cycle in the working mode of working for 9 seconds and stopping for 6 seconds. This function can discharge the air generated during cleaning and improve the cleaning effect.

5、關機

5. Shut down

按“超聲”鍵一次，超聲停止工作，關閉實驗室超聲波清洗儀器背部總電源開關，然后拔掉電源插頭，排出清洗液，將內槽擦拭干凈。

Press the "ultrasonic" key once, the ultrasonic stops working, turn off the main power switch on the back of the laboratory ultrasonic cleaning instrument, then unplug the power plug, discharge the cleaning fluid, and wipe the inner tank clean.
