    Safety Information

    The BNT-Prison-Communication-jammer-J250CW is designed with safety as a priority:

    • The electromagnetic signals comply with national environmental electromagnetic wave health standards
    • Signal intensity is relatively small and unharmful to the human body
    • Only affects cell phone reception, making normal connection between cell phone and base station impossible
    • No damage occurs to cell phones themselves
    • Other electronic equipment works normally as the jamming signals are restricted to regulated frequency bands
