Unit Care

Display

Cleaning the Screen — Warm water and soap will work fine. You can also use ammonia-type cleaners like Windex. Do not use any type of abrasive cleaners. They will remove the Anti-Reflection coating from the glass.

Buttons

Inspect the buttons — Make sure that no buttons are stuck in the down position. If one is stuck, wiggle the button to free it back to the normal position.

Debris in the keyboard contacts — In case there is dirt or other debris covering the contacts inside the keypad, press down on the button in question and wiggle it to try to restore its function.

Connectors

Clean the Connections — Corrosion or oxidation could occur on the power cable connector pins and fuse-holder. This can prevent sufficient power from flowing to the unit. Clean the connections to be sure. Some- times the substance is clear and not easily seen.
