Case Sealing ============ All HUNTER's are built with integral seals to provide a high degree of protection against atmospheric moisture, corrosive gases and accidental immersion, therefore HUNTER should not be opened. The Battery Seal ---------------- This is a small 'O' ring seal running in a machined groove in the battery plug and seated on a machined face in HUNTER casing. This seal requires a smear of silicon grease to assist in seating. Seal Specification ------------------ ============ ========= Dimension Part no. ============ ========= 1.5mm x 30mm HUN-05710 ============ ========= Replacement seals may be obtained from HUSKY Computers or authorised agents.
