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 (+, –, x, ÷); independent memory; percentages; square roots; 20-digit approximations; date calculations; other mixed calculations.
Approximately 1460 (680 for SF-4400), under the following conditions: 8-character name 10-character telephone number 20-character address Memo: Approximately 2780 (1290 for SF-4400), 20-character memos.
3. TO REPLACE THE BATTERIES Screw 1) Loosen the screw on the back of the SF-4400/4600B 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. RESET Caution: Be sure to remove only one battery at a time. Otherwise, you will lose all data stored in memory.
4. DATA TRANSFER SF-4400/SF-4600B can transfer customers data to other SF-4400/SF4600B with memory protection only when replacing the LCD or the outer case. How to transfer the data. * Before connecting the cable (SB-60/62), be sure to reset the slave machine to clear all 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-4400/4600B 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.

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 RESET button RESET 1. Switch on power and press the RESET button with a thin, pointed object.
