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 SHIFT and then LIGHT causes the backlight to light and stay lit as long as you continue to operate the SF Unit, or until you press LIGHT again to turn it off manually. Leaving the backlight on for long periods greatly reduces battery life!

About the Power Supply

You can perform such operations in the Telephone Directory, Memo, Schedule Keeper, Calendar, To Do, Expense or Reminder modes.

About data compatibility

Whenever you exchange data with a CASIO SF Unit, there are certain restrictions concerning data compatibility. Send data You cannot send data to the CASIO SF-A Series Units (SF-A10, etc.). Some SF Units, CSF Units, NX Units do not have modes that are included with this Unit. For example, some Units do not have a Reminder Mode or an Expense Mode. Data from a mode cannot be received by an SF Unit, CSF Unit, NX Unit unless that SF Unit, CSF Unit, NX Unit also has the same mode. Data cannot be sent from this SF unit to a CASIO SF-5580, 5580E, 5590SY, 5590SYE, 5780, 5780E, 5790SY, 5790SYE, 5980, 5980E, 5990SY, 5990SYE, 6500SY, 6700SY, 6900SY, 7100SY or 7200SY unit. When data is sent from this SF Unit to a CASIO CSF or NX Unit, data stored in Telephone Directory items FREE1 through FREE6 is stored in the Telephone Directory MEMO item of the unit to which you are sending data, with newline symbols between the FREE items. When data is sent from this SF Unit to a CASIO CSF or NX Unit, all text is blue. When data is sent from this SF Unit to a CASIO CSF or NX Unit, all calendar highlighting is blue. The euro mark can be transferred between two SF-4900ER/SF-4980ER/ SF-4985ER units. Euro marks are replaced by blank spaces when data is transferred from a SF-4900ER/SF-4980ER/SF-4985ER unit to an older model. Receive data You cannot receive data from the CASIO SF-A Series Units (SF-A10, etc.). Some SF Units, CSF Units, NX Units have modes that are not included with this unit. Data from such modes cannot be received by this unit. The Schedule Keeper of some SF Units is capable of storing multiple-date data items. Whenever you transfer such a data item to the your SF Unit, it is automatically converted to a single-date data item. The date used is the one that starts the original multiple-date data item. 95
PART 6 Data Communications Some SF Unit models have a mark protection feature to protect against accidental erasure of data. This unit does not feature mark protection, and so such data is received by this unit disregarding the mark protection. Data cannot be sent to this SF Unit from a CASIO SF-5580, 5580E, 5590SY, 5590SYE, 5780, 5780E, 5790SY, 5790SYE, 5980, 5980E, 5990SY, 5990SYE, 6500SY, 6700SY, 6900SY, 7100SY or 7200SY unit. When data is sent to this SF Unit from a CASIO CSF or NX Unit, CSF/NX Telephone Directory MEMO item data is stored in the Telephone Directory FREE1 item of this SF Unit. When data is sent to this SF Unit from a CASIO CSF or NX Unit, all text becomes monochrome. When data is sent to this SF Unit from a CASIO CSF or NX Unit, all calendar highlighting becomes monochrome. All CSF/NX calendar dates that are orange or green are converted to highlighted dates. This unit cannot receive PERSONAL, FAMILY, TIMETABLE, or GOLF memo data from a CASIO NX Unit.

About communications parameters.
Communications parameters make it possible for two communicating units to understand each other. The following explanations are provided for your information only. The only thing you need to remember is that the parameters of the send unit and the receive unit must be identical. Otherwise you will not be able to transfer data successfully. PARITY Parity is used for error detection during data exchanges. You can set the SF Unit parity as even (E), odd (O), or none (N). BIT LENGTH The bit length parameter states how many bits are to be used for each character. You can set the SF Unit bit length as 7 bits or 8 bits. BPS The letters BPS stand for bits per second, and this setting represents the speed at which data is sent. The SF Unit lets you set a speed of either 4800 or 9600. 98
