2. SPECIFICATIONS Data storage: Storage and recall of telephone, memo, schedule, reminder data; calendar display; secret area; editing; memory status display. Clock: World time; reminder alarm; schedule alarm; daily alarm; accuracy under normal temperatures: ±3 seconds average. Calculation: 10-digit arithmetic calculations; arithmetic constants (+, –, ×, ÷); independent memory; percentages; square roots; 20-digit approximations; date calculations; other mixed calculations.
Approximately 1459(SF-4600RS)/3019(SF-4900RS), under the following conditions: 8-character name 10-character telephone number 20-character address Memo: Approximately 2785(SF-4600RS)/5764(SF-4900RS), 20-character memos.
3. TO REPLACE THE BATTERIES 1) Loosen the screw on the back of the unit that holds the battery compartment cover in place, and remove the cover. 2) Loosen the screw that secures one of the two battery holders in place and remove the battery holder. Screw RESET Caution: Be sure to remove only one battery at a time. Otherwise, you will lose all data stored in memory. 3) Replace the old battery with a new one, making sure that the positive (+) side of the new battery is facing up (so you can see it).
4. DATA TRANSFER SF-4600RS/4900RS can transfer customers data to other SF-4600RS/4900RS with memory protection only when replacing the LCD or the outer case. * Before connecting the cable (SB-60/62), be sure to reset the slave machine to clear all data. How to transfer the data 1) Turn off the power switch and connect the two units using the cable (SB-60/62) as shown in the drawing. SB-60/62 accessory cable 2) Turn on the power switch of each machine. 3) The slave machine must be set the date of Feb.
Setting up for Data Communications The following procedures describe what you should do to set up for data communications between two SF Units or between an SF Unit and a personal computer. In addition to hardware connections, it details how to set up the communications parameters and how to set up the SF-Units to receive data. By following these instructions carefully, you can be ensured of successful communications every time. To connect two SF Units 1. 2. 3.
If the units have another condition, reset as above. • To change the parameters 3. 5) ∇ Use the and — cursor keys to change the selected parameter on the display. Use the and cursor keys to change the high-lighted setting of the currently selected parameter. Press to store them in memory. ∇ 1. 2. ∇ 5. Set up the slave machine 1. While an initial screen is displayed, press twice to display the second function menu. * If the password isn't registered in the SF unit, display shows X instead of "1".
2. Press 4 to select DATA COMM. 4 3. Press 1 to select SEND. 1 4. Press 3 to select ALL DATA. 3 5. Press to start the send operation or to abort the operation without sending anything. • Data is send in the sequence: Telephone Directory, Memo Mode, Reminder Mode, Schedule Keeper, Calendar. • To abort the send operation at any time, press . • If an error occurs during the send operation, the message “TRANSMIT ERROR!” appears on the display. Press to clear the error message. 6.
5. OPERATION REFERENCE 5-1. RESET OPERATION The following procedure erases all data stored in the memory of the SF Unit. Perform the following operation only when you want to delete all data and initialize the settings of the SF Unit. Remember-you should always keep copies of important data by writing it down, by transferring it to a personal computer or other SF Unit. To reset the SF Unit's memory 1. Switch on power and press the RESET button with a thin, pointed object.
5-2. TO ADJUST THE DISPLAY CONTRAST ∇ ∇ 1 Enter the Telephone Directory Mode. • You could enter any mode except the Calculator mode here. 2 Press and confirm that the "S" indicator is on the display. 3 Press . 4 Use the and keys to adjust the contrast. 5 After you are finished, press to clear the contrast adjustment display. 5-3. TO CHECK THE MEMORY STATUS Hold down and then hold down to display a screen that shows the current memory status. To clear the memory status display, release .
