• Use the and keys to scroll a page, day, or week at a time.

• Note that with most screens, not all of the contents scroll. Only the portion of the screen that has multiple lines scrolls (such as the DESCRIPTION field of a SCHEDULER item), while other parts

(such as TIME and DATA fields) remain unchaged.

■

Using the Menu Bar

The menu bar provides you with a selection of pull-down menus containing commands that are very similar to those found in many desktop computer applications.

The availability of the menu bar, the type of pull-down menus it contains, and the contents of the pulldown menus depend on the mode you are in and the type of operation you are currently performing.

See the Appendix at the back of the User’s Guide for a full list of commands that appear in each menu.

■

Make backup copies of important data!

Your BN Unit employs flash memory, which makes it possible to store large volumes of data and to recall data quickly and easily. Data is retained when power is turned off and even when batteries go dead, but it can be corrupted or lost entirely due to operational mistakes or malfunction. Data contents can also be corrupted or lost due to strong electrostatic charge, strong impact, or extremes in temperature and humidity. All of this means that you should always keep back-up copies of important data by transferring it to a personal computer or by writing it down somewhere.

2-3. Backlight Operation (BN-20 only)

■

About the EL backlight (BN-20 only)

• The BN-20 is equipped with an EL backlight that allows easy viewing of display contents in a theater, or anywhere else where lighting is dim.

• Note, however, that frequent or extended use of the EL backlight shortens battery life.

The following shows how backlight use affects battery life under controlled test conditions*.

Backlight Operation Battery Life

3 minutes per hour Approximately 65 hours

15 minutes per hour Approximately 35 hours

* Test Conditions

• “Battery Life” is the number of hours before battery failure when the unit is left on with 5 minutes of a processing operation and 55 minutes of continuous display only (no processing operation) per hour in the CONTACTS Mode, plus the backlight operation described below. The above values assume ambient temperature of 20

°

C, starting with a fresh set of new batteries.

• “Backlight Operation” is the number of minutes backlight is turned on per hour during the display only (no processing operation) period.

• Be sure to use alkaline batteries. Manganese batteries provide very short battery life.

Important!

• Note that pressing SHIFT and then LIGHT causes the backlight to light and stay lit as long as you continue to operate the BN Unit, or until you press LIGHT again to turn it off manually.

Leaving the backlight on for long periods greatly reduces battery life!

■

Backlight Operation (BN-20 only)

The electro-luminescent backlight of the BN-20 Unit helps to keep your on-screen data bright and easy to read at all times. There are two different operations you can use to turn on the backlight. One turns the backlight on for about 15 seconds, while the other procedure leaves the backlight on as long as you keep operating the keyboard.

Leaving the backlight on for long periods greatly reduces battery life!

To turn on the backlight for 15 seconds

Press the LIGHT key to turn on the backlight. The backlight will turn off automatically after about 15 seconds.

Pressing LIGHT while the backlight is lit turns it off.

To leave the backlight on as long as you input data

Press SHIFT and then LIGHT to turn on the backlight. In this case the backlight will remain on as long as you continue to press keys. It turns off automatically if you do not perform any key operation for about 15 seconds.

Notes

• The backlight will turn off automatically and not turn on when the LIGHT key is pressed while data communication operation is in progress.

• The backlight may also suddenly turn off and fail to turn back on whenever battery power is low.

— 13 —

2-4. Power Supply

Your BN Unit can be powered by two AA-size alkaline batteries (LR6(AM3)) or the following optional

AC adaptor.

Optional AC Adaptor: AD-A70140

AD-A70140D-OP: for U.S.A. and Canada (AC 100 ~ 120 V)

AD-A70140G-OP: for Europe except U.K. (AC 200 ~ 240 V)

AD-A70140A-OP: for Australia (AC 200 ~ 240 V)

Impotant!

• Normally the flash memory of the BN Unit retains its data when power is turned off and even when batteries go dead. Misoperation or other problems, however, can cause data to become corrupted or lost. Always keep separate copies of important data.

■

Low Battery Warning

The message BATTERIES ARE GETTING WEAK! REPLACE THEM AS INSTRUCTED IN THE

USER’S GUIDE. appears whenever battery power drops below a certain level. Replace the batteries immediately after this message appears.

• See the manual that comes with PC sync for Windows for a list of supported CASIO Digital Diary models, required PC system configuration and cable requirements.

Note

• If an imported spreadsheet has more than 32kb of data, anything over 32kb is automatically deleted.

— 24 —

4-2. Connecting the CASIO BN Unit to PC

Important!

Be sure to turn off the power of both your BN Unit and computer before connecting them. Failure to do so can result in damage to the BN Unit, your computer, or the Mini Cradle.

1. Plug the connector at the end of the Mini Cradle´s cable into your computer´s serial port (RS-

232C).

• The serial port is normally labeled COM1, COM2, COM3, or COM4.

• If the serial port on your computer does not match the Mini Cradle´s connector, you need to purchase an adaptor. See the documentation that comes with your computer for details.

To connect the Mini Cradle to the CASIO BN Unit

1. Make sure that the power of both the BN Unit and your computer is turned off.

2. Open the Mini Cradle port cover on the left side of the BN Unit as shown in the illustration.

Open

— 25 —

3. With the side marked CASIO facing up (so you can see it), plug the Mini Cradle connector straight into the BN Unit port.

Important!

• Make sure you insert the connector as far as it will go, until you hear it snap securely into place.

• Do not apply undue force! Doing so can damage the Mini Cradle connector or BN Unit port.

To disconnect the Mini Cradle from the CASIO BN Unit

1. Make sure that the power of both the BN Unit and your computer is turned off.

2. While squeezing the buttons on both sides of the connector, pull it straight out from the Mini

Cradle port to remove it.

4-3. PC sync for Windows (Brief explanation)

If you want to known PC LINK Software for BN-10/20 (PC sync for Windows) in detail, refer to the

User´s Guide for this software.

This software is similar to FA-127/128 regarding to operation, but have some features which don´t exist with FA-127/128.

The following PC, OS for PC and Display for PC are recommended.

PC:

OS for PC:

IBM PC or compatible one

Windows 3.1 or Windows 95

Display for PC: VGA or one which have more pixels than VGA

And the available information and remarks for repair will be described below.

■

Features

1. START button on the mini cradle

1 To start perform all data transfer (ordinary transfer, data synchronization, complete backup and retrieval of data) between BN Units and PC, the round START button on the mini cradle always must be pressed finally.

2 Pressing START button at the time of turning off BN Unit, BN Unit is forced to turn on. At this time, the following display appears.

“DATA COMMUNICATION IN PROGRESS! TO STOP, PRESS [ESC]”

Pressing ESC button, the following display appears. “STOPPED!”

Pressing ESC button once more, the MENU mode display will appear.

2. High speed data transfer

The default transfer speed is 38400 b.p.s..

The data transfer speed can be set to 1200~38400 b.p.s. (1200, 2400, 4800, 9600, 14400,

19200, 28800 and 38400 b.p.s.) because BN Units have more memory capacity than another

CASIO Digital Diary. The high speed data transfer causes often to miss the data transfer.

Therefore, the high speed LINE DRIVER/RECEIVER circuit is set to Main PCB assembly.

3. Data synchronization

The BN Unit can be synchronized with a PC sync file, i.e. the PC file and the BN Units can be brought up to an identical data state. New records existing on both units in an identical state will be filtered automatically, to avoid creating doubles. PC LINK software FA-128 for SF-

5590SY/5790SY/5990SY have this operation also. But “lgnore” setup with FA-128 is deleted with PC sync for Windows for BN Units.

4. Complete backup and retrieval of data

Performing the following procedure described below, all the data transfer included secret area data can be performed without knowing and entering the password.

Threfore, the data transfer from a Unit to another Unit using SB-60/SB-62/SB-63 cable as the other CASIO Digital Diaries doesn´t exist with BN units.

●

PROCEDURE

The menu items (“Casio” ➝ “Backup” ➝ “Send” or “Receive”) enable you to transfer all the data of your BN Unit fast and efficiency to your PC, e.g. before changing batteries, and - if necessary -back to your BN Unit.

While transferring some data between the BN Unit and PC, the following display always appears.

“DATA COMMUNICATION IN PROGRESS! TO STOP PRESS [ESC]”

<Data transfer from BN Unit to PC>

1 To back up the data, choose “Casio”, then “Backup”, and then “Receive” with PC.

2 Next, press START button on the mini cradle. All data is now transferred to PC.

* Time for this transfer (BN-10: about 10 minutes/ BN-20: about 20 minutes) is very long compared with the other transfer even if the transfer is performed with 38400 b.p.s..

3 Give the backup file a file name after the transfer.

<Data transfer from PC to BN Unit>

1 To retrieve the data, choose “Casio”, then “Backup”, and then “Send” with PC.

2 Then select the relevant back-up file.

3 Next, press START button on the mini cradle. All data is now transferred to BN Unit.

* Time for this transfer (BN-10: about 10 minutes/BN-20: about 20 minutes) is very long compared with the other transfer even if the transfer is performed with 38400 b.p.s..

4 After data transfer, the MENU mode display will appear with BN Unit.

Note

• Backup files always have the extension *.bak and cannot be edited, i.e. you cannot open them choosing “File”, then “Open”.

■

Remarks

1. Select *the default PORT (COM1 PORT) ordinarily. Otherwise, the data transfer will not be performed. Select another PORT if the data transfer is not performed with COM1 PORT.

* The default PORT will be appeared by the following procedure.

Casio ➝ Transmission Setup... ➝ Serial

2. If PC LINK software FA-127/(128) and PC sync for Windows were installed in your PC and some files (the extension “.twf”) made by FA-127/128 exist, these files will be opened with PC sync for

Window at the time of opening one of these files with mouse directly.

Be sure to select “File” and then “Open ” after opening the software FA-127/(128).

To discriminate and control the files having the same extension “.twf”, three kinds of holders should be made in your PC.

3. To print data in a file after exporting data in this file having the extension “.twf”, you had better choose the ANSI [Plain ANSI text] at this time. These data in this file will be saved with the extention “.text”.

Printing many data in the file having the other extension (for example, “.csv”), these many printed data are very difficult to see.

1. Refer to 9-1. Block Diagram.

2. Common mode coil (EF601) is used to prevent the emission of high frequency noise from AC

Adapter jack.

— 45 —

3. When battery voltage becomes to be about 2.1 V, BLD1 terminal voltage becomes to be about 0 V and the low battery message appears even if AC Adapter is used.

4. When battery voltage becomes to be about 1.6 V, BLD2 terminal voltage becomes to be about 0 V and the power is forced to be turned off to prevent the corruption of memory even if AC Adapter is used.

5. When AC Adapter voltage becomes to be about 2~3 V instantly and suddenly, BLD2 terminal voltage becomes to be about 0 V and the power is forced to be turned off.

6. When adapter output voltage becomes to be about 4.5 V, P1 terminal voltage becomes to be about 0 V, and the power is force to be turned off.

7. The thermal compensation is set to VLCO voltage circuit for LCD using a thermistor (TH).

When ambient temperature becomes low, LCD display becomes dimmer. At this time, VLCO terminal voltage becomes higher by a thermistor (TH), and then LCD display becomes lighter.

8. FUSE (F601) adjacent to the battery (F601) will be cut off with current of 1A for over 2 seconds.

9. If batteries are not loaded or battery power is low, BLD2 terminal becomes to be about 0 V even if AC Adapter is used. Therefore, BN Unit power is not turned on or is forced to be turned power off as described to the page 15.

9-3. Function

Refer to 8. LSI PIN FUNCTION, 9-1. Block Diagram and 10. SCHEMATIC DIAGRAMS.

9-3-1. Memory

LSI303 is Static RAM for operation, and not for user with BN Unit itself, but for user concerning MO-

DEM BW-100.

User’s data are saved in flash ROM (LSI304 (LSI304 and LSI306 with BN-20)) with BN Unit itself, and saved in flash ROM (LSI308) concerning MODEM BW-100.

And LSI301 is a mask ROM for operation.

Data saved in a flash ROM are not deleted even if power is not supplied. Therefore, the lithium battery for memory backup is not necessary with BN Unit. It is easy to write data using the flash ROM like

RAM. And the overall deletion of data is performed instantly using the flash ROM different from EEPROM.

LSI308 is a flash ROM for OS program.

Data for OPERATION CHECK are saved in this LSI308 also.

NVRAM (Non Volatile RAM) are set interior TAB LSI (LSI4, LSI5) for driving LCD.

Therefore, the display made before battery replacement appears again after battery replacement.

9-3-2. P Key and RESET Key

Pressing P Key, CPU, Gate array and other devices are forced to be initialized using the circuit for

RESET (RESET by hardware) even if power is turned off.

On the other hand, pressing RESET Key, CPU, Gate array and other devices are forced to be initialized using the software because RESET Key is connected to NMI (Non-Maskable Interrupt) terminal.

This RESET by software can be performed while turning power on as described to the page 16.

If any malfunctions or (and) abnormal symptoms exist even after this RESET operation by software, try to initialize CPU pressing P Key (RESET by hardware).

9-3-2. Line receiver/ driver IC (IC501)

Miss data transfer is often occurred by long wire data transfer lines and rapid data transfer without a line receiver/ driver. Data transfer speed is 38400 b.p.s. (MAX.) with BN Unit.

Data transfer speed of CASIO Digital Diary prior BN Unit is 9600 b.p.s..

So the high speed line receiver/ driver IC (IC501) is necessary with BN Unit.

This IC is satisfied with electrical requirement of EIA-232E and CCITT V.28.

— 46 —

9-3-3. Bias voltage generator IC (IC708) for LCD

LCD is driven by steps shaped AC voltage as shown to the right.

The number of steps shown to the right is three. This is called 1/3 bias.

Generally, if the quantity of pixels in a LCD common line is N dots, the quantity of bias is 1/ N . At this time, contrast of LCD display becomes maximum. The quantity of pixels in a LCD common line is 160 dots. Therefore, the quantity of bias is set to 1/13 by this bias voltage generator circuit.

9-3-4. Countermeasure against EMI (Electro Magnetic Interference) with BN Unit

The copper films for shield and wires connecting between grounds on PC board are used for countermeasure against EMI. If these parts doesn’t exist, data transfer between BN Unit and MODOEM /PC will not be performed.

9-3-5. EL (Electroluminescence) driver IC (IC701) (BN-20 only)

This IC is a DC/AC inverter for EL.

V5SYS terminal voltage (DC 5 V) is converted to AC output terminal voltage (AC 180 V P-P , 100 Hz, triangle wave form) loading EL. When V5SYS terminal voltage becomes less than about 4.5 V or EL button on the keyboard is pressed twice and so on , ENA terminal voltage becomes to be about 0 V, and blue light from EL disappears.
