This voice guidance can be used for the purpose of production support such as giving the operator information about the number of pieces produced, work progress management and the operation rate of sewing machine, though the initial setting is required.
The operation panel is provided as standard with a USB port. This means that the sewing machine data management and software updating can be carried out with ease by means of the USB port.

The machine is provided as standard with 50 different sewing patterns. The machine permits easy changeover of sewing patterns for effortless execution of an inexhaustible range of sewing specifications.
The LK-1903S is also able to sew buttons using the same data used for the LK-1903 (Data in EP-ROM are enabled by conversion).
Auto-lifter mechanism utilizing a system
The machine is provided as standard with auto-lifter that uses a stepping-motor system. This helps reduce operator fatigue.
The work clamp foot lift can be set to a maximum of 13mm.
LED light (light quantity in five levels + light-out function)
The LED light that illuminates the needle entry area is provided as standard. The LED light is provided with the six-step changeover switch to control its brightness and light-out.
