The CF-C1 was also designed to be used while standing during presentations and checking inventory in stores, etc. That's why it adopts a Hand-Free Ergonomic Strap.
This strap is wider in the middle and uses a urethane material which provides elasticity as well as a comfortable fit that is not too tight. In addition, the bottom of the PC is designed with a dome so the palm fits naturally snugly against this dome enabling a secure grip on the PC from the bottom. If you slightly bend your fingers, the palm of your hand naturally forms a cup. The dome on the bottom of the PC was designed with this hand movement in mind. These innovative designs enable the PC to be held for long periods without fatigue.
