Maximizing Camera Life and PerformanceF3Technical Notes and IndexC Notes on Monitors• Monitors and electronic viewfinders are constructed with extremely high precision; at least 99.99%of pixels are effective, with no more than 0.01% being missing or defective. Hence while thesedisplays may contain pixels that are always lit (white, red, blue, or green) or always off (black), this isnot a malfunction and has no effect on images recorded with the device.• White or colored streaks may be visible when bright subjects are framed in the monitor. Thisphenomenon, known as “smear,” occurs when extremely bright light strikes the image sensor; it ischaracteristic of image sensors and does not indicate a malfunction. Smear may also take the formof partial discoloration in the monitor during shooting. It does not appear in images recorded withthe camera except in the cases of movies and of images recorded with Multi-shot 16 selected forContinuous. When shooting in these modes, we recommend that you avoid bright subjects suchas the sun, reflected sunlight, and electric lights.• Images in the monitor may be difficult to see under bright lighting.• The monitor is lit by an LED backlight. Should the monitor begin to dim or flicker, contact yourNikon-authorized service representative.The Battery• Check the battery level before using the camera and replace or charge the battery if necessary. Donot continue charging once the battery is fully charged as this will result in reduced batteryperformance. Whenever possible, carry a fully charged spare battery when taking pictures onimportant occasions.• Do not use the battery at ambient temperatures below 0°C (32°F) or above 40°C (104°F).• Charge the battery indoors with an ambient temperature of 5°C to 35°C (41°F to 95°F) before use.• When charging the battery inserted into the COOLPIX S4200 using the Charging AC AdapterEH-69P or a computer, the battery is not charged at battery temperatures below 0°C (32°F) orabove 45°C (113°F)• Note that the battery may become hot during use; wait for the battery to cool before charging.Failure to observe these precautions could damage the battery, impair its performance, or preventit from charging normally.• On cold days, the capacity of batteries tends to decrease. Be sure that the battery is fully chargedbefore heading outside to take pictures in cold weather. Keep spare batteries in a warm place andexchange as necessary. Once warmed, a cold battery may recover some of its charge.• Dirt on the battery terminals can prevent the camera from functioning. Should the batteryterminals become dirty, wipe them off with a clean, dry cloth before use.• If the battery will not be used for some time, insert it in the camera and completely exhaust beforeremoving it for storage. The battery should be stored in a cool location with an ambienttemperature of 15°C to 25°C (59°F to 77°F). Do not store the battery in hot or extremely coldlocations.• Always remove the battery from the camera or optional battery charger when it is not being used.When inserted, minute amounts of current flow even when unused, and the battery may becomeexcessively drained and no longer function. Turning the camera on or off while the battery isexhausted can result in reduced battery life.• Recharge the battery at least once every six months and completely exhaust it before returning itto storage.• After removing the battery from the camera or optional battery charger, return the battery to thebattery case and store in a cool place.
