Sony HVL-F43M Operating Instructions Manual page 75

• Remove the batteries only after turning the power off and waiting several
minutes, when changing the batteries. The batteries may be hot, depending on
the battery type. Remove them carefully.
• Remove and store the batteries when you do not intend to use the camera for a
long time.
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. The
low-battery indicator 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.
