EC-356 (650-0865) Power Faxback Doc. # 3728 About the Power Supply The Organizer is powered by two CR2032 lithium batteries (Radio Shack Cat. No. 23-162.) About battery life Replace batteries as soon as possible whenever you notice either of the following: No display when you switch power on. Dimming or failure of the display during operation. Very cold temperatures (below 40 degrees F) may affect the lithium batteries and cause the unit to fail to switch on. In this case, correct operation should resume once the unit returns to a normal temperature. Cautions: All data stored in memory is lost if you remove both batteries at the same time. Be sure that you keep a separate copy of all important data that you store in Organizer. Battery Precautions Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the Organizer. Note the following precautions. Be sure that the positive (+) side of each battery is facing up (so you can see it). Never mix batteries of different types. Never mix old batteries and new ones. Never leave dead batteries in the battery compartment. Remove the batteries if you do not plan to use the Organizer for a long period. Replace batteries at least once every two years, no matter how much you use the Organizer during that period. Never try to recharge the batteries supplied with the Organizer. Do not expose batteries to direct heat, let them become shorted, or try to take them apart. Keep batteries out of the reach of children. If swallowed, consult with a physician immediately. To replace the batteries 1. Loosen the screw on the back of the Organizer that holds the battery compartment cover in place, and remove the cover. 2. Loosen the screw that secures one of the two battery holders in place and remove the battery holder. Caution: Be sure to remove only one battery at a time. Otherwise, you will lose all data stored in memory. 3. Replace the old battery with a new one, making sure that the positive (+) side of the new battery is facing up (so you see it). 4. Replace the battery holder and secure it by tightening its screw. Be careful that you do not over tighten the screw. 5. Repeat steps 2 through 4 for the other battery. Be sure to replace both batteries. Never mix old batteries with new ones, and be sure to use CR2032 lithium batteries only. 6. After you replace both batteries, replace the battery compartment cover and secure it by tightening its screw. Be careful that you do not over tighten the screw. Battery life Approximately 280 hours continuous in Telephone Directory; approximately 240 hours repeating one minute of entry and 10 minutes of display in Telephone Directory; approximately 12 months for memory back up.
