H is a quality built, precision instrument designed to provide you with many years of Service-fres, depend- ability. Your new calculator is capable of per- forming a wide range of problem-solving as- signments . . . instantly, silently and easily. A tiny, solid state chip of silicon, no larger than this letter ““‘M”, contains the brainpower for your calculator. Engineers refer to this miracle of miniature wizadry as, “Super Large Scale Integration,” (S-LSI). It is your assurance of optimum reliability and increased durability. Carefully review the instructions covering your instrument. Work through the examples illus- trated, and within a very short time you will become proficient in the many advantages offered by your new calculator. Mower Disposable Battery Model (D) Your calculator uses two standard 1.5 volt batteries type ““AA”’ available at most drug, department and camera stores. To operate, disconnect the adaptor cord and turn power switch ON’ (an interlocking switch inthe AC socket wil prevent battery use if the plug remains connected). When the battery weakens, display will dim. When you are replacing the batteries, please observe the polarity of bai- teries. Polarity of batteries are printed on ihe boitom of battery compartment. To prevent the damage from battery leak, please remove the batteries, when the calculator will not be used for the long period of time. Rechargeable Battery Models (R) AC Operation Connect the charger to any standard electrical Gutlet and plug the jack into the Calculator. After ihe above connections have been made, the power switch may be turned “OWN.” (White connected to AC, the batteries are automatic- ally charging whether the power switch is “ON” or “OFF."} Battery Operation Disconnect the charger cord and push the power switch, “ON,” an interlock switch in the calculator socket will prevent battery operation ii the jack remains connected. With normal use 2 a full battery charge can bé expected to supply about 2 to 3 hours of working time. When the battery is low, figures on display will dim. Do not continue battery operation, this indicates the need for a battery charge. Use of the calculator can be continued during the charge cycie. Battery Charging Simoly follow the same procedure as in AC operation. The calculator may be used during the charge period. However, doing so in- creases the time required to reach full charge. lf a power cell has completely discharged, the calculator should not be operated on batiery power until it has been recharged for at least 2 hours, unless otherwise instructed by a not- ice accompanying your machine. Batteries will reach full efficiency after 2 or 3 charge cycles. Controls and Naicators “ON” Switch: Turns calculator “ON” and “ORF, C Clear Key: Press once to erase fast entry.
