WARNING

•Keep batteries out of the reach of children. If a battery is accidentally swallowed, call a doctor immediately.

Notes on handling batteries

•Do not expose batteries to excessive heat. Never store them in the truck or glove compartment of a vehicle during the summer or place them near a fire or hot surface. Even hot, direct sunlight may cause them to explode.

•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.

•Battery power tends to weaken as the temperature drops. It also weakens after heavy use, recovering gradually after a short break. Power gradually decreases when batteries are not used for a long time. Check battery power before use; replace batteries with a new set before they are completely exhausted.

•Battery performance may differ with each brand, due to modification in specifications or improvement in performance.

Four AA-type alkaline-manganese, lithium, or rechargeable NiCd or Nickel-Metal Hydride (Ni-MH) batteries are required to power the SB-28.

•For fast recycling times: NiCd batteries are recommended followed by (2) Ni-MH, (3) alkaline-manganese, and (4) lithium batteries.

•For increasing the number of flashes per battery set: at normal temperatures, lithium batteries are recommended followed by (2) alkaline- manganese, (3) Ni-MH, and (4) NiCd batteries; at low temperatures, lithium batteries are recommended followed by (2) Ni-MH, (3) alkaline- manganese, and (4) NiCd batteries.

•Ni-MH batteries feature approx. the same battery power as 1000mAh NiCd batteries.

•1000mAh NiCd batteries have approx. 1.4 times the power capacity of 700mAh NiCd batteries.
