Sony HVL-F45RM Mode D'emploi page 53

• Do not use lithium-ion
batteries because repeated
flash use makes the batteries
hot and the flash will no longer
fire.
• The flash frequency and
number of flashes provided
by new batteries may vary
from the values shown in the
table, depending on the time
elapsed since manufacture of
the batteries.
• 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.
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 moistened with water or
tepid water, 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.
• If fingerprints or debris are
stuck to the lens or flashtube,
we recommend that you
gently remove any debris and
then wipe the lens or flashtube
clean with a soft cloth.
