Maintenance - Sony HVL-F42AM Operating Instructions Manual

Temperature
• The flash unit may be used over a temperature range of 0 °C to 40 °C.
• Do not expose the flash unit to extremely high temperatures (e.g. in direct
sunlight inside a vehicle) or high humidity.
• To prevent condensation forming on the flash, place it in a sealed plastic bag
when bringing it from a cold environment into a warm environment. Allow it to
reach room temperature before removing it from the bag.
• Battery capacity decreases at colder temperatures. Keep your camera and spare
batteries in a warm inside pocket when shooting in cold weather. Low-battery
lamp may blink even when there is some power left in the batteries in cold
weather. Batteries will regain some of their capacity when warmed to normal
operating temperature.
• This flash unit is not waterproof. Be careful not to bring it into contact with
water or sand when using it at the seashore, for example. Contact with water,
sand, dust, or salt may result in a malfunction.

Maintenance

Remove this unit from the camera. Clean the flash with a dry soft cloth. If the flash
has been in contact with sand, wiping will damage the surface, and it should
therefore be cleaned gently using a blower. In the event of stubborn stains, use a
cloth lightly dampened with a mild detergent solution, and then wipe the unit clean
with a dry soft cloth. Never use strong solvents, such as thinner or benzine, as these
damage the surface finish.
