If you still have trouble after trying the RESET operation, you may have a
hardware problem. If so, consult with your nearest CASIO dealer.
General Precautions
Never try to take the SF Unit apart.
Avoid strong impact and sudden temperature changes.
At very low temperatures, the display response time may slow down or the
display may fail completely. This is temporary and correct operation should
return at normal temperature.
To avoid serious damage to the SF Unit caused by leaking batteries, replace
batteries once every two years, regardless of how much you use the SF Unit
during that time.
Never use thinner, benzine or other volatile agents to clean the exterior of the
SF Unit. Instead, wipe it off with a soft cloth dampened in a solution of water
and a mild, neutral detergent. Wring the cloth out until it is almost dry.
If the SF Unit is exposed to strong electrostatic charge, the display may dim
or the SF Unit may lock up. To correct this situation, switch power off, and then
remove and then replace the batteries.
Do not press the keys with a pen, pencil or other sharp object.
The SF Unit may cause interference with radio or television reception. Keep
it away from such appliances when you are using it.
Note that pressing
stay lit as long as you continue to operate the SF Unit, or until you press
again to turn it off manually.
Leaving the backlight on for long periods greatly reduces battery life!
