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.
