W702406010 - Control panel (Panel Board)

W702406010 – Roland RF-640 Control Panel (Panel Board)

The Roland control panel (Panel Board) – OEM ref. W702406010 – is the machine’s operator interface: it comprises the LCD display, the membrane keypad and the circuit board that controls the display and command input.

This circuit board manages the display of menus and machine statuses (BASE, HEATER, SETUP, BUSY) and transmits the operator’s commands (FUNCTION, MENU, ENTER, PAUSE, navigation, on/off) to the main circuit board. A faulty panel renders the machine inoperable even when the rest of the electronics are functioning.

Supplied as a complete, assembled unit ready for installation, using genuine Roland parts (OEM).
