Notes on batteries 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) alkalinemanganese, (3) Ni-MH, and (4) NiCd batteries; at low temperatures, lithium batteries are recommended followed by (2) Ni-MH, (3) alkalinemanganese, 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. 87
