15. Daily Maintenance
Daily maintenance is essential to keep the unit ready for operation at full
performance. Do maintenance from time to time as instructed below.
Body, Keyboard & Laser Scanner Aperture
CAUTION
Never use solvent such as thinner, benzene, toluene, acetone, etc., or plastic body
may melt, deform, whiten, etc.
Do not rub the laser scanner aperture with hard cloth (gauze, etc.) strongly. Flaw on
the aperture may cause errors in barcode reading.
Do not rub the keyboard too strongly. Keytop marks may fade or key closure
contact may deteriorate.
When wiping the body with damp cloth, squeeze out water well. If not, metallic
parts such as connector pins or switch contacts may deteriorate, resulting in poor
contact.
Maintenance Directions
Gently wipe off dirt or stain from the body by using soft cloth damped with a bit of
water. To clean the surface of laser scanner aperture or keyboard, use soft cloth
damped with a bit neutral cleanser thinned with water.
Connectors
Maintenance Directions
If the unit is left in high-humidity or corrosive atmosphere for a long time, connectors
may be corroded, resulting in poor contact. To refresh the contacts, repeat plug-in
and out several times. (Note that too many plug-in/out operations may waste the
contacts.)
