Precautions o Make sure that polarities of all the batteries are properly aligned. Incorrect polarity alignment

may cause unexpected damage to your equ lpment. Replace all batteries at the same time. Do not mix battery brands, types or old batteries with new ones. Remove batteries when not using your equipment for a long time. Batteries may tend to leak if left too long in your equipment and may cause serious damage.

Never throw used batteries into f ire since they may explode, causing unexpected damage or InJuryto you. Store batteries in a cool place, and out of reach of children. Batteries are very sensitive to cold and performance tends to deteriorate at temperatures near freezing point. Performance is restored as soon as batteries are brought back to room temperature. Keep a set of batteries in a warm pocket when shooting in cold weather to substitute if the others no longer perform well. (New batteries are packed at the time of shipment, but because of inherent self-discharging, performance gradually deteriorates as time goes by. In such a case, replace the packed batteries with brand-new ones.)

3) Aim the Spotmeter so that a small circle in the center of focusing screen (seeillustration) is placed on a section of the subject to be measured. Depress the metering button and read the number on the light meter scaleindicated by the needle.

lf light from the subject is too low to enable the scaleto be read, pressthe scale illuminator button on the side of the grip of the Spotmeter V as you look in the eyepiece. The use of the scale illuminator will make it easy to read light levels EV 1-B on the left end of the scale.

5) Turn the outer ring of the meter calculator located on the side of the meter so that the number read f rom the light level scale is aligned with the largetriangular index at the bottom of the calculator f ace. lf , for example, the number indicated on the l i g h t l e v e l s c a l ei s E V 1 2 , t u r n t h e o u t e r r i n g s o
