The warranty applies to defects in material or manufacture . This
warranty does not cover product parts subject to normal wear, thus
possibly considered consumables (e .g . batteries) or for damage to
fragile parts, e .g . switches, rechargeable batteries or glass parts .
The warranty further excludes a reduction in water tightness . The state
of water tightness is not a permanent property and should therefore
be regularly maintained . Please note, opening and repairs performed
by unauthorized individuals will void any warranty .
