● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is
available through many electronic supply outlets.
IMPORTANT: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are
improperly removed or installed, the keyboard might not function properly.
● You can clean under a key with a swab moistened with isopropyl alcohol and squeezed out. Be careful not

confined areas. Allow the parts to air dry before reassembly.
