In the hinge portion, the upper and lower main bodies were connected via extremely flat flexible cables. The cables were about 3.5mm wide and about 0.1mm thick.

No special waterproofing features could be found in the hinge portion itself, but rubber sealing members were used in the portions where the cables were inserted into the upper and lower bodies to prevent water from entering.
