Notes:

Replacing any component at will can damage the intrinsically safe structure of the instrument.  
Activating the instrument after the allowed storage period may affect the instrument's performance and retention period.
The instrument should be stored in a dry and dust-free environment and charged before reuse.
Do not clean the instrument with organic solvents, soaps, or silicone-containing solutions to avoid sensor damage.
Do not charge the instrument for more than 8 hours.
Regularly test the instrument with standard gas to check whether the sound, light and vibration alarms are normal.
The standard gas provided by the manufacturer or the national certified enterprise should be selected for calibration.
When the instrument is warming up, do not enter the hazardous environment for testing to avoid accidents.
Avoid violent impact and squeezing by strong external forces.
