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.

Magic Beam Mode
It is possible for this unit to communicate with the following CASIO units: JD-5500, JD-6000, JD-
6000A, JD-7000, and JD-7000R using infrared light, without direct cable communication.
Effective range
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.

When the unit does not work properly ...
The unit may stop working properly after it is subjected to strong electrostatic charge or strong impact. If this
happens, first check to make sure that the main batteries and back-up battery are correctly installed, and then
perform the following operation.
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.

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)
To replace the back-up battery
1. Switch power off.
2. Loosen the screw of the small battery compartment cover on the back of the unit, and remove the back-
up battery compartment cover. (Figure 4)
3. Remove the old battery.
4. Wipe off a new battery with a soft cloth.Then, load it into the compartment making sure that positive (+)
side is facing up (so you can see it.) (Figure 5)
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 6)
