    Tips on Speedlight care Avoid physical shocks Do not drop the SB-28 or hit it against a hard surface as this may damage its precision mechanisms. Never disassemble the SB-28 Never attempt to disassemble or repair the SB-28 yourself. The SB-28 contains high-voltage circuitry which can cause electric shock.

  • Page 87: Notes On Batteries

    • When loading batteries, make sure the SB-28 is turned off, then follow the + and – symbols inside the battery chamber. • If the SB-28 is not used for more than two weeks, remove the batteries and store them in a dry place at 20°C (68°F) or below.
  • Page 88 • Lithium batteries incorporate internal safety switches. When the battery becomes hot, its safety circuit is activated, cutting off power. This often occurs when the SB-28 is operated in the repeating flash mode. The flash ready-light will not light up after firing approx. 24 exposures. However, battery power will recover when the temperature goes back to normal.

  • Page 89: Troubleshooting

    NOTE The SB-28 incorporates a microcomputer to control flash operations. In rare cases, the SB-28 may not work properly even after fresh batteries are properly installed. If this happens, replace the batteries with the SB-28's power turned on.
