Note:
1. Improper operation or inappropriate use of the environment may weaken the operating performance of the instrument. For the safest and most effective use of the instrument, please read the following correct operating procedures and safety
2. Please read the user manual carefully before any operation.
3. The sensor window and filter membrane must be kept clean. If the sensor window is blocked or filtered by the water film, this may result in a reading lower than the actual gas concentration
4. Replacement of batteries, maintenance parts and other operations can only be carried out in a safe environment.
5.To ensure the safety and proper use of the instrument, its operation and maintenance may only be performed by qualified personnel.
6.Every day before use, please check the instrument's accuracy in fresh air and ensure that the measurement error is within the permissible range.If it exceeds the permissible error range, the instrument must be calibrated.
7.Keep the alarm in your mouth; no foreign objects should obstruct it, otherwise the alarm or the identification of the alarm information will not be heard.
8.The battery must be removed and replaced in a known and safe environment.
