Precautions - Panasonic DMW-FL28E Operating Instructions Manual

Precautions

When nicad batteries are used:
The batteries will deteriorate in performance if left unused for a long period. Discharge them by manually operating the
flash (repeatedly making it light until the flash indicator does not light 30 seconds after blinking) and fully recharge the
batteries.
When the flash is used in a low-temperature location:
The batteries will deteriorate in performance if used in temperatures below the normal temperature (20 oC). This causes
a reduction of the number of lighting times and/or a lengthening of the interval between flashes. It is recommended to
prepare fully-charged spare batteries. However, battery performance will be restored when the ambient temperature
rises to normal temperature.
Do not leave the flash in conditions of high temperature.
Do not leave or store the flash in a location where the temperature rises to 40 oC or higher. High temperatures affect the
internal structure of the flash. (In particular, never leave the flash in a car during summer.)
If the flash gets dirty, apply a small amount of neutral mild detergent and wipe the flash clean with a piece of soft
cloth.
Do not use solvents such as thinners or benzines, as they will dissolve the surface of the resin coating of the flash unit.
