Product Maintenance 1. Open Or Close The Protective Cover With Special Care, Because The Filter Is Valuable And Fragile. The Filter Should Be Kept Clean And Polished, And Often Wiped With A Soft Cloth Or Fur 2. Water Should Not Be Allowed To Enter The Filter Hood, And There Should Be No Water Vapor Condensation Inside The Hood. To Frequently Check Whether The Desiccant In The Desiccator Becomes Damp (From Orange To Dark Color), Otherwise It Should Be Replaced In Time Or The Desiccant Will Be Taken To The Oven To Bake Dry To Make It Back To Orange Before Use 3. Rainfall (Snow, Ice, Etc.) Or A Longer Period Of Rain, In Order To Protect The Radiation Table, The Observer Should Be According To The Specific Circumstances Of The Best Cover, After The Rain Stops That Is To Open The Cover
