7. CIRCUIT EXPLANATIONS 7-1. Power supply circuit 1) Diodes rectification bridge By diodes rectification bridge, alternating voltage is converted into DC voltage, and the electrical voltage is done filtering of by Capacitor C4. 2) Power supply circuit for B-6 The electrical voltage which puts in resistor 3 when line voltage includes anomaly changes, and transistor Q1 becomes on status, and CS signal is done outgoing of by this, and VP is supplied than Power supply B-6.
7-4. Reset circuit The voltage fluctuation of VDD is controlled of IC10 (S-80727AN). CPU is done Reset by pushing Reset Switch or drifting VDD. Vdd S-80727AN 2 3 1 CPU Reset SW 17 7-5. Reset Data communication between CPU and EEPROM IC11(BR93LC46A). EEPROM is Rom that write / erase is possible electrically. BR93LC46A is a non- volatile register, and serial data of 16 bit can be memorized with 64 register.
[ Data reading procedure ] When the CPU read the data of EEPROM, CPU send the CS signal and SK signal to EEPROM. Then CPU send the address to EEPROM, and then EEPROM return the data to CPU. CS SK Address DI DO Data Output data here [ Data writing procedure ] When the CPU save the data to EEPROM, CPU sends the CS and SK signal to EEPROM. And CPU send the address and data to EEPROM from pin No. 15. When the EEPROM writes the data, EEPROM outputs the busy signal form DO terminal to CPU.

This test is continued till off mode or electric power supply enters it.
10. PROGRAMMING THE CE-3700 SERIES CASH REGISTERS The Casio CE-3700 series is capable of a versatile range of features and function that give it the capability to readily adapt to almost any retail environment. The cash register is programmed at the factory with the most standard operating features and functions. Your local business requirements, however, may call for other functions of a totally different keyboard layout.
1 Use Program 4 to read the assignment of functions to programmable keys and then make changes. 2 Use Program 3 to read the definition of machine features and key functions and then make changes. 3 Use Program 1 to read programming of time, date and unit price, amounts, rates, etc. and then make changes. 10-2. Using the worksheets The worksheets included in this manual for Program 3 and Program 1 help to make your programming simple and accurate.
11. OPERATION Operation of your cash register is designed to be simple enough to master without any special technical knowledge. Anytime you make a mistake in operation, an error tone sounds and further operation becomes impossible to protect your valuable data. Whenever this happens, you can resume normal operation after pressing the “C” key. Printing of the symbol “—” can be programmed when the “C” key is operated in the REG1, REG2, and RF modes.
12. ERROR CODES Error codes appear on the display whenever you make a mistake during operation. The following table shows the actual error codes, their meanings, and the actions to take to correct the situation. Error Code E 01 Meaning Position of MODE switch changed before finalizing the current operation. E 41 Setting of the receipt ON/OFF button Changed before finalizing of the registration under another setting Prohibited clerk/cashier number(7 ~ 15) is entered during cashier interrupt registration.
