Ready-light warning inside the camera’s viewfinder
Note
The SB-800 incorporates a microcomputer to control flash operations. In rare cases, the
SB-800 may not work properly even after fresh batteries are properly installed. If this
happens, replace the batteries while the SB-800’s power is turned on.
Warning
• Batteries should not be exposed to excessive heat such as strong sunshine, a fire,
or the like.
• Dry batteries should never be recharged in a battery charger.
• Do not expose the SB-800 to water as this may result in an electric shock or cause
the unit to catch on fire.
