■ Display Indicators The following shows the names of the various indicators that appear on the display and explains what they mean. : Data runs off the top of the screen. Scroll displayed data by pressing , , , and . SHIFT: Keyboard is shifted between upper-case and lower-case input. The punctuation marked above the keys in blue can also be input while the keyboard is shifted. CAPS: Keyboard is shift-locked so all text input is upper-case.
2-2. Modes and Cursor Keys etc. In order to use the powerful features and functions of the BN Unit, you must first enter one of the following modes. • SCHEDULER • CONTACTS • MEMO • EXPENSE MANAGER • SPREADSHEET • CLOCK • MAIL/FAX* You can enter a mode by pressing its mode key, or by using the Mode Menu. * An optional modem is required to perform the operations in the MAIL/FAX Mode.
■ Using the Cursor Keys Use the large round cursor key located in the upper right corner of the BN Unit’s keyboard whenever you have to perform any operation that requires movement up, down, left, or right. In addition to actually moving the input cursor, the cursor key is also used to select menu bar menus and the commands inside of a menu.
■ Important Precautions Note the following important precautions whenever using your BN Unit. • Never expose the BN Unit to fire. • Avoid temperature extremes. Do not locate the BN Unit in direct sunlight, near a window, near a heater, etc. • In very low temperatures display response may slow down or fail entirely. This condition is temporary and operation should resume under normal temperatures. • Avoid areas subject to excessive moisture, dirt, and dust.
To reset after viewing data 1. After the DATA ERROR message appears, press OK (Yes). 2. In response to the message that appers (DATA ERROR! CONSULT YOUR USER’S GUIDE FOR CORRECT PROCEDURE.), press OK. • This enters the CLOCK Mode. 3. Now you can enter other modes to recall data and make handwritten copies if you want. 4. After recalling tha data you want, perform the RESET operation under “To reset the BN Unit” on page 16. To reset immediately 1. After the DATA ERROR message appears, press ESC (No). 2.
■ Memory Status You can use the following procedure at any time to check the current status of BN Unit memory. To check memory status 1. Press MENU BAR to display the menu bar. 2. Use to highlight SYSTEM, and then press 3. Use to highlight CAPACITY, and then press OK. Memory used . Remaining memory 4. Press ESC to close the dialog box. ■ Memory Management The memory of your BN Unit is designed to make your nomal data input and recall operations as quick and efficient as possible.
• The following dialog box appears after you press OK to start memory management. • You can press ESC at any time to stop the memory management procedure. ■ Storage Capacity The 2-Mbyte memory capacity of the BN-20 (1-Mbyte for the BN-10) includes a 1,499,136-byte user area (687,104-byte for the BN-10). The following shows examples of what this means for the storage of data in each mode.
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*.
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.
Important! • Use only the following optionally available AC adaptor model with this product: AD-A70140. • Use of a AC adaptor model other than that specified above can result in serious damage to the AC adaptor or the BN Unit, or other serious problems. • Always turn off the BN Unit before connecting the AC adaptor. • The AC adaptor may become warm to the touch after very long term use. This is normal and does not indicate malfunction.
3. RESET OPERATION and BATTERY REPLACEMENT 3-1. Reset Operation Warning! The following procedure erases all data stored in the memory of the BN Unit. Perform this operation only when you want to delete all data and initialize the settings of the BN Unit. Remember-you should always keep copies of important data by writing it down, or by transferring it to a personal computer. To reset the BN Unit 1. Press the power on key (BN-10: ON, BN-20: ON/OFF) to turn on power. 2.
4. In response to the message that appears, press OK to reset the BN Unit and clear all memory contents, or ESC to abort the reset procedure without doing anything. 5. If you pressed OK in the above step, a second confirmation message appears. Press OK to reset the BN Unit and clear all memory contents, or ESC to abort the reset procedure without doing anything. • Pressing OK in the above step starts the actual reset procedure. 6.

4. DATA COMMUNICATION 4-1. General You can exchange data between your BN Unit and a personal computer using PC sync for Windows. This provides the data communication capabilities illustrated below. • See the manual that comes with PC sync for Windows for details on connecting to a computer and setting up for communication.
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 (RS232C). • 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.
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.
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.

6. ERROR MESSAGES Message Cause Action THAT ALARM TIME IS ALREADY PASSED! The time you are trying to set for an alarm is already passed. This is merely a warning message that appears for about one second. After that, the dialog box closes and the data is stored without the alarm. THAT ALARM TIME IS ALREADY USED! The time you are setting for an alarm is already used. Change the alarm time to one that is not yet used.
Message Cause Action MEMORY IS FULL! You are trying to input data while memory is already full. First try performing the memory management operation to see if more memory can be made available. If this message still appears, it means that memory is really full. Delete data you no longer need to make room for more data. CELLS IN THE RANGE YOU ARE DELETING CONTAIN DATA. DELETE THEM ANYWAY? Some of the cells in a range you are deleting in the SPREADSHEET Mode contain data.
7. TROUBLESHOOTING ■ Power Supply PROBLEM POSSIBLE CAUSES RECOMMENDED ACTIONS Nothing appears on the display when power is turned on. 1.The battery switch on the back of the unit is set to REPLACE BATTERIES. 2.Battery power is low. 3.Display contrast is too light. 1.Slide the battery switch to NORMAL OPERATION. 2.Replace batteries (page 18). 3.Adjust display contrast (page 10). The BN Unit does not operate normally after batteries are replaced. Problem with BN Unit operational settings.

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.
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.
