Protection against EMI
Many radars use conductive paint inside their covers to protect against EMI (Electro Magnetic
Interference). This model, however, is not painted, but has a shield cover over the DU board for
protection against EMI.
Waterproofs
The display unit conforms to the IEC standard IPX5; namely, waterproof against water jets. Even
the small hole to the right of the arrow keys, which is where the aural alarm is released, is
waterproof. A “breathing sheet” between the panel cover and the buzzer allows air to pass and
prevents water from being drawn into the enclosure during atmospheric pressure changes.
