Safty Guide and Maintenance
To avoid damage to meter, never drop or subject it to shock.
Avoid storping meter in places with high temperature and/or humidity.
Be careful excessive temperature changes that could cause humidity and
internal condensation, resulting in malfunction.
If the temperature of the meter drops to -10°C or beyond, response of
the LCD becomes extremely slow and displays are difficult to read. At
temperatures between 0 and 10°C the LCD will become somewhat slower
than normal but this does not hinder usage. Also, when the temperature
exceeds 50°C, the LCD will turn black and will be hard to read. This will return
to normal when the temperature returns to normal.
Do not place the meter in direct sunlight during midsummer or near
heaters, etc., as the temperature of the meter will rise beyond that of the air
temperature. Be careful when using the meter in hot locations.
Remove battery if meter is not used for an extended period. Batteries can
leak and damage the exposure meter. Dispose of used batteries properly.
