[ 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.

[ 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.After finish writing, EEPROM outputs the ready signal from DO terminal to CPU.

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 thecapability to readily adapt to almost any retail environment. The cash register is programmed at thefactory with the most standard operating features and functions. Your local business requirements,however, may call for other functions of a totally different keyboard layout.

This section explains the different functions available, as well as the procedures that you can use totailor the cash register to specific needs. Programming is simplified through the use of worksheets foreach function, and step-by-step flow charts that walk you through each procedure.

10-1. Setting the proper MODE for programming

• Program Modes and feature

You should perform the procedure shown blow as the first step of programming. Notice that theflowchart ends with an arrow on the bottom. This indicates that you should continue to the nextprogramming procedure for the mode you specify.

• Procedure

Set the Mode switch to Program

Enter a number to specify the program mode (1 ~ 4)

Press the Sub total key.The display should show the letter “P” followed by theprogram number you specified (i.e. P3 = Program mode 3).

Press the # 1 key.

Enter 4-digit password.Skip this step when the password is not programmed.

Press the Sub total key.

key on standard keyboard.

Note: Program mode 1 is automatically set when the Mode switch is set to Program fromanother setting.

• Recommended programming sequenceGenerally, you should perform programming in the following sequence. Note that we recommend youcheck what is programmed for each mode before proceeding to the programming operation.

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 yourprogramming simple and accurate. We recommend that you fill out the pertinent worksheet beforeattempting actual programming.1) Carefully read each definition and specify a selection.

Each definition is following by a Specification column which contains numeric values(Usually toindicate a simple YES or NO answer). Determine the correct value according to your need andenter it in the Selection column to the right.

2) Total each set of selections to calculate each program code digit.Three selections(a,b,c) make up a set. Add up each set of selections and fill in the totals in theProgram code column for data items D8 through D1.

3) Program the feature or function.Be sure that you have filled in all of the selections and program code digits for the entire worksheet,and follow the procedure noted for the feature or function you are programming.

4) Check the printed program receipt against the worksheet.Perform program read operation in each program mode to print setting which you haveprogrammed, to check then against the worksheet. We recommend that you do so and keep a copyon record to help out should it become necessary for you to change the program.

10-3. Clearing a machine lock up

If you make a mistake in operation, the cash register may lock up to avoid damage to programs andpreset data. Should this happen, you can use the following procedure to clear the lock-up withoutlosing any memory data.

• Procedure

Set the Mode switch off.

While holding down the Key, set the mode switchto X1.

Release the key.

You should see “FFFFFFFFFF” on the display. If 10 of F’s arenot shown on the display or if another character is shown,immediately set the mode switch to OFF and start from thebeginning of this procedure. IF you don’t see “ FFFFFFFFFF”on the display, do not press the Sub total key.

Finalize the procedure.

11. OPERATION

Operation of your cash register is designed to be simple enough to master without any special techni-cal knowledge. Anytime you make a mistake in operation, an error tone sounds and further operationbecomes impossible to protect your valuable data. Whenever this happens, you can resume normaloperation after pressing the “C” key.

Printing of the symbol “—” can be programmed when the “C” key is operated in the REG1, REG2, andRF modes. The number of the “C” key operations can also be programmed for printing on the generalcontrol Read/Reset reports.

As you become familiar with the key layout of the cash register, you may find that your keyboardentries are getting ahead of the receipt and journal printer. But you never need to worry that the cashregister will miss anything. A built-in key input buffer memory holds entries for up to eight keys to letthe cash register catch up when you slow down or stop.

Another thing you don’t need to worry about is power outages. Your register features built-in recharge-able lithium batteries that return such information as program data, registration records, data, item, andconsecutive number.

These and other features and functions of the CE-3700 series electronic cash register make it awelcome addition to any retail environment.

• Performing daily cash register operationsThe actual operations that you perform with your cash register will depend in the nature of your ownbusiness. The following outline shows the most common operations in the order they are usuallyperformed.
