How memory capacity is calculated

There is no limit on the amount of memory you can use in each mode, but the limit on the total amount of data stored is 4,096 bytes. The following shows how many bytes the data in each mode takes up. One character requires one byte of memory.

— 4 —

Mode Bytes per Data Item

Telephone Directory (name) + (telephone number) + 15 Schedule (description) + 12 Data Memo (memo name) + (memo contents) + 3

Examples:

Telephone Directory data only

When all items use 10 characters for the name and 12 characters for the phone number, you can store approximately 110 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 Modes.

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-5500/C-310 for the first time. The all-reset operation is described in section 4. Please be sure you understand the following before using the JD-5500/C-310.

Make back-up copies of important data!

The electronic memory in the JD-5500/C-310 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-5500/C-310 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-5500/C-310, 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.

Things to check for if you are having problems with Magic Beam

• If battery power is weak, you have to move the two units closer together.

• If the two units are at an angle of more than 20 degrees from each other, you have to move them closer together.

• If an object is blocking the path between the two units, communication will be impossible.

• Outdoors, near a window, or in other brightly lit areas, you may have to move the two units closer together or you may not be able to send data at all.

• If there is a third unit nearby, communication may be impossible.

1. Loosen the screw that holds the back-up battery compartment cover in place, and remove the cover.

2. Use a thin, pointed object (like a paper clip) to press the RESET button inside the battery compartment cover. When you do, the "Reset?" screen should appear.

3. Make sure that the pointer is located at "No," and then press EXE. The "Check time!" message should appear on the display.

4. Press EXE again, and then use the Timekeeping Mode to set the current time.

5. Replace the battery compartment cover.

— 12 —

5. BATTERY REPLACEMENT

Low Battery Warning

The message, "Low Battery" appears whenever battery power drops below a certain level (about 2.70 V). Replace the main battery immediately after this message appears. 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 unit 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 in section 4.

Important!

Incorrect use of batteries can cause them to burst or leak, possibly damaging the interior of the unit. 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 do not plan to use the unit for a long time.

• To avoid damage to the unit from leaky batteries, replace the main batteries at least once every two years, and the back-up battery once every three years.

• Never mix batteries of different types.

Warning!

• Never try to recharge the batteries supplied with the unit.

• 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.

To replace the main batteries

1. Switch power off.

2. Loosen the screw of the large battery compartment cover on the back of the unit, and slide the battery

compartment cover in the direction noted by the arrow. (Figure 1)

3. Remove the old batteries.

4. Making sure that the positive (+) and negative (-) ends of the batteries are facing correctly, load two new

batteries into the compartment. (Figure 2)

• Be sure to replace both old batteries with two new ones.

5. Insert the tabs on the bottom of the battery compartment cover into the slots of the battery compartment

and carefully close the cover. Secure the cover in place with the screw. (Figure 3)

Figure 1 Figure 2 Figure 3

To replace the back-up battery
