Nikon SB 11 - Manual (Page 32)

TIPS ON SPEEDLIGHT CARE
To remove dirt or fingerprints,
wipe with a dry soft or silicon-
treated cloth. Never use thinner,
benzine or alcohol, since they
might damage the plastic parts.
To clean the Wide-Flash Adapter,
wash it with soap and water.
Never use a brush, as this may
damage it.
If you do not plan to use the unit
for more than two weeks, remove
the batteries to avoid possible
damage to the circuitry by battery
leakage. If leakage should inad­
vertently occur, take the flash unit
to your nearest Nikon authorized
service facility.
To prevent damage to the flash
unit's electronic circuitry, keep
the camera away from places
where the temperature is likely to
go higher than 50°C, such as
inside the trunk of a car in the hot
summer sun; also do not store the
unit in exceptionally damp
places. Use the SB-11 within the
range of —10°C~ -l-50°C.
