Ricoh GF-1 - Manual (Page 5)

EN - 
Do not fire the flash direct to the eye at short distance. It may
damage the eye. When taking flash picture especially toward
a baby, it is recommended to keep the flash unit at least 1
meter (3.3 feet) away from the subject.
Do not leave or store the flash unit in temperatures over 40˚C,
such as in an automobile.
Caution
Contact with fluid leaking from a battery can lead to burns. If
part of your body comes in contact with a damaged battery,
rinse the area with water immediately. (Do not use soap.)
If a battery starts to leak, remove it immediately from the
equipment and wipe the battery chamber thoroughly before
inserting a new battery.
Do not allow the flash unit to get wet. In addition, do not
operate it with wet hands. Both pose the risk of electric
shock.
Do not fire the flash at drivers of vehicles, as this may cause
the driver to lose control and result in a traffic accident.
Do not use the flash in unstable locations. You may lose your
balance, fall or drop the flash, resulting in injury.
To prevent the flash from overheating or deteriorating, keep
the number of continuous flashes to no more than 20 flashes.
After 20 continuous flashes, do not use the flash for at least
10 minutes.
With cameras other than Type R, the flash will fire
automatically and continue firing in interval shooting mode;
do not use the flash in this mode.
Do not use benzine, thinner or other alcoholic agents to clean
the unit.
Remove the batteries when not in use for a long period of
time.
