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.

— 3 —

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 (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 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 Mode.

2. 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 unit for the first time. The all-reset operation is described on section 4.

Please be sure you understand the following before using the unit.

Make back-up copies of important data!

The electronic memory in the unit 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 unit 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 unit, 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.
