Improper battery replacement may cause a change or loss of memory contents.

Be sure to write down any important information stored in the memory before replacing the battery.

Make sure the power is turned off before replacing the battery.

Do not press ONOFF until the battery replacement procedure is completed.

1. Precautions

Since improper use of the battery may cause leakage or explosion, strictly observe the following instructions.

Insert the battery with the positive side (+) correctly facing up.

Never throw the battery into a fire because it might explode.

Keep the battery out of the reach of children. Because the battery in the Organizer was installed at the factory, it may become depleted before the specified expiration time is reached.

If the display becomes dim and difficult to read, immediately replace the battery with a new one. Continued use of the Organizer with an exhausted battery can alter or clear the memory contents.

1.Press ONOFF to turn the power off.

2.Loosen the screw and remove the battery holder cover on the back of the unit. (Slide the cover off.)

3.Install a new battery with the positive side (+) facing up into the upper or lower empty holder. (Fig. 1)

4.Remove the exhausted battery by prying it out with a ball-point pen. (Fig. 2)

5.Replace the holder cover and secure it with the screw.

6.Press ONOFF to turn the power on.

If nothing appears on the display, press the RESET switch and press C•CE .

Do not press SHIFT ENTER . Pressing SHIFT ENTER clears all the memory

contents. 7. Set the clock.
