Panasonic /}/ Power Supply 1, Operation on household power line The AC adaptor and dry battery pack are used, The dry battery pack may be either with or without patteries. Bat- teries are not consumed when AC adaptor 1s used. , Operation on dry batteries The dry battery pack with four size “AA ary calls is used. . Operation on rechargeable battery pack loptional) Rechargeable battery pack is used. Model JE-850 operates on the re- chardeable battery pack while the bat- tery is being recharged from the power line through AC adaptor (floating charge}. !f the power switch of Model JE-850 is turned off, the battery is recharged quicker (quick charge). Operating Time on Battery Power Sources ambient temperature 68° F Battery Operating time Rechargeable battery pack 1-032 ¥P Approx. 3 hours Dry battery pack JL-012 with: Panasonic size AA i Approx. 5 hours alkaline dry cells Dry battery pack JL-012 with: Panasonic size 4A | Approx. 1% hours Hi-Top dry celts Use of highly reliable Panasonic batteries is recommended. Low-quality cells may leak, possibly damaging inside com- nonents of Model JE-850 as well as giving a shorter operating time. Notes on AC Adaptor 1. Model JE-850 Electranic Calculator is specially designed for exclusive use with the AC adaptor, Model JL-O22, It should not be used with other AC adaptors. 2. the red tamp on the AC adaptor is lighted while tt ts charging the re- chargeable battery pack, It starts flash- ing when the pack is nearing the full charge. 3. This charge pilot lamp is not iighted when the AC adaptor is used in com- bination with the dry battery pack. . If the calculator is not used for an ex- tended period of time, disconnect the AC adaptor from the wall outlet. How- ever, under normal line voltage condi- tions, no damage will result even if the adaptor is not disconnected. Notes on Dry Batter Pack 1. When the battery indicator dot ap- pears on the display panei while Model JE-850 is being operated on the dry battery pack, immediately replace the dry cells with new ones. . The dry batteries are replaceable with size AA cells of any brand, Panasonic alkaline cell Model AMS ts economical for long operation of the calculator. . When JSeaving the dry battery pack unused for langer than a month, re- move the batteries frorn the pack without fail. Otherwise, the batteries may corrode, possibly damaging the calculator. 10 Pre-operation 1. Select the Dower source to be used, and connect the equipment securely. instructions 2. Turn on the power switch. 3. The numbers to be entered should he a maximum of & dig!ts. For a decimal, the decima! part should be 7 digits or less, . When results of a calculation exceed 8 digits, the answer will automatically shift to the right and drop off the least significant decimal digits. This allows the most significant digits to be displayed. When a calculated result has a larger integral part than 8 digits, the overflow lamp *‘E*” lights near the left end of the display panaf. [n this case, the decimal point displayed shows the place of 100 million; therefore, an approximate answer with 8 mast significant digits can be obtained by multiplying the displayed figure by 100 million (or 19° times). The “E’’ lamp also tights when model JE-850 is operated for dividing a number by zero. The displayed overflow can be released by pressing the clear key"). a, Press keys one by one, in the same order as you write down an arithmetic problem. and tne answer will be displayed by pressing the ¢> key, 6. Correction of erroneous entry When a number is entered erroneously, that number can be cancelled by pressing the clear entry key immediately thereafter. Then, operate the keyboard for entry of the correct number and continue the keyboard operation. /. Correction of erroneously pressed opera- tional Key.
