Memory Capacity Screen

Use the following procedures to check the status of the memory. One procedure displays the amount of memory used and the how much memory is remaining. The other shows you how many data items you have stored in each mode.

To display the memory capacity:

1. While the main menu is displayed, or any time you are in the Telephone Directory, Schedule, Data Memo "Diary", or Calendar mode, press FUNCTION.

2. Use and to select "Memory Capacity" and then press EXE.

• The memory values shown above are the total for both the Open Memory Area and the Secret Memory Area.

• Press AC/ON to clear the memory capacity screen.

To display the number of items in each mode:

1. While the main menu is displayed, press FUNCTION.

2. Use and to select "Number of items" and then press EXE.

Data Memo : 11

• If you perform the above procedure while in the Open Memory Area, the number of items stored in the Open Memory Area only are displayed. To see the number of items in the Secret Memory Area, you must perform the above operation while accessing the Secret Memory Area.

How memory capacity is calculated

There is no limit on the amount of memory you can use in each mode, but the total amount of data that can be stored is 4,096 bytes. The following shows how many bytes the data in each mode takes up. One character (each newline operation counts as a character also) takes up one byte.

— 5 —

Mode Bytes per Data Item

Telephone Directory (name) + (telephone number) + (address. etc.)

+ 15 Schedule (description) + 12 Calendar 6 bytes per calendar that contains highlighted

dates Data Memo "Diary" (memo name) + (memo contents) + 3

Examples:

Telephone Directory data only

When all items use 10 characters for the name, 12 characters for the phone number, and 16 characters of the address, you can store approximately 70 items.

Schedule data only

When all items use 20 characters, you can store approximately 120 items.

Data Memo "Diary" data only

When all items use 10 characters for the memo name and 10 characters for the memo content, you can store approximately 170 items.

Sort Sequence

The following table shows the sequence used for sorting data in the Telephone Directory and the Data Memo "Diary" Mode.

3. GENERAL GUIDE

Very important stuff! Here's where we tell you how not to lose important data stored in memory. Also, be sure to perform the all-reset operation before using the JD-6000/7000 for the first time. The all-reset operation is described on page 12.

Please be sure you understand the following before using the JD-6000/7000.

Make back-up copies of important data!

The electronic memory in the JD-6000/7000 store and recall information quickly and easily. But that information is retained only as long as power is supplied by the batteries. Should the batteries go dead, or should you remove both batteries at the same time, data stored in memory can be lost entirely. Data can also be corrupted or lost due to a strong electrostatic charge, strong impact, or extremes in temperature and humidity. All of this means that you should always keep written back-up copies of important data.

General Precautions

Warning!

• Never expose the unit or batteries to direct heat or flame.

• Avoid use or storage in very low temperatures. This may cause display response to slow down or fail entirely. Very low temperatures can also shorten battery life.

• Avoid use or storage in very high temperatures. Even prolonged exposure to direct sunlight can damage the unit. Leaving it on the dashboard of a closed car, or on a heater, is even worse.

• Avoid using or storing the unit where there is high humidity or a lot of dust. Never allow liquids to come into contact with the unit.

• Avoid dropping the unit or otherwise subjecting it to strong impact.

• Never bend or twist the unit. Carrying it in your back pocket, for instance, can subject the JD-6000/7000 to abnormal bending and twisting.

• Never try to take the unit apart.

• Do not press the unit's keys with a pen, pencil, or other sharp object.

• To clean the JD-6000/7000, wipe it with a soft cloth. When necessary, you may wipe the exterior with a soft cloth that has been dipped in a weak solution of a mild, neutral detergent and water.

• Never use strong liquid cleaners such as lacquer thinner or benzine to clean the unit.

• In no event will CASIO or its suppliers be liable to you or any other person for any damages, including any incidental or consequential expenses, lost profits, lost savings, or any other damages arising out of the use of this product.

To Perform Secret Reset:

• Perform the steps described under "To Perform All-reset" above, but select "Del Secret Data" in place

of "Reset" in step 4.

For JD-6000

Following are the initial settings produced by the all-reset operation:

Home Time Zone: London (LON) Home Time Setting: 12:00 AM, January 1, 1990 World Time: New York (NYC) 12/24-Hour Clock: 12-Hour Clock Alarm: OFF Alarm Time: 12:00 AM Hourly Time Signal: OFF Key Input Tone: ON Date Format: Month/Day/Year Language: English TV Manufacturer: EMERSON VCR Manufacturer: EMERSON 1

For JD-7000

When the JD-6000/7000 Does Not Work Correctly...

If the JD-6000/7000 are jolted by a strong electrostatic charge or by severe impact, it may not work properly. In such a case, first check to make sure that the main batteries and back-up battery are correctly installed, and then perform the following operation:

1. Remove the screw that holds the battery compartment cover in place and remove the battery

compartment cover.

2. Press the RESET button with a thin, pointed object.

3. Look for the message, "Exit," to be highlighted on the display.

4. Press EXE. Now the message, "Check time!" should be on the display.

— 13 —

5. BATTERY REPLACEMENT

Low Battery Warning

The message, "Main Battery Getting Weak! Replace it!" appears whenever battery power drops below a certain level. Replace the main battery immediately after this message appears. When the battery is getting weak between 2.85V and 2.55V, the unit will show the message. Whenever the low battery warning message appears, the OFF key will be the only function that works. If you don't turn the unit off yourself, power will switch off automatically about 30 seconds after the low battery warning appears.

Replacing Batteries

• Main Batteries Two AAA size batteries (LR03 (AM-4) or R03 (UM-4)) are used for the main power supply. The JD-6000/ 7000 will not operate at all if main batteries are not installed.

• Back-up Battery One CR2032 lithium battery supplies power to the memory and protects its contents.

Memory contents are lost when both the main batteries and the back-up battery are removed. Be sure always to leave one of the batteries or back-up battery in place to protect memory contents. If, however, you remove the main battery for any time, memory retention will depend entirely on the condition of the back-up battery. Over a long period of time with just the back-up battery in place, memory contents are likely to be damaged. If memory seems corrupted, clear it using the RESET procedure described on page 12.

Important!

Incorrect use of batteries can cause them to burst or leak, possibly damaging the interior of the JD-6000/7000. Note the following precautions:

• Be sure that the positive (+) and negative (-) poles of the batteries are facing in the proper direction.

• Never leave dead batteries in the battery compartment.

• Remove the batteries if you expect not to be using the JD-6000/7000 for a long period of time.

• To avoid damage to the unit from leaky batteries, replace the main batteries at least every two years, and

the back-up battery every three years. Batteries should be replaced no matter how much you use the unit during that time.

• Never mix batteries of different types.

Warning!

• Never try to recharge the batteries supplied with the JD-6000/7000.

• Do not expose batteries to direct heat, short-circuit them, or try to take them apart.

• Keep batteries out of the reach of small children. If swallowed, consult a physician immediately.
