• Do not use any other type of batteries.
• Non-rechargeable. Never attempt to recharge these batteries in a battery charger. 

Otherwise, they may explode.

• Depending on battery specifications, when these batteries become hot, the safety circuits 

are activated, cutting off power. This often occurs when the flash unit is operated in the 
repeating flash mode. Battery power will recover when the temperature returns to normal.

• When installing the battery, turn off the power of the Speedlight and never reverse the 

polarity of the batteries.

• If the battery terminals become soiled, remove dirt and smudges before use, as these 

may cause damage.

• If exhausted batteries are used at low temperatures, the Commander or Speedlight units 

may not work properly.

• When taking photographs in low temperatures, use fresh batteries, and keep a set of 

spares in a warm place (e.g. a coat pocket).

• Battery power tends to weaken as the temperature drops. At low temperatures, flash 

capacity decreases and recycling takes longer. Battery power will recover if they are not 
used and allowed to return to normal temperature.

• Do not throw used batteries into a fire. Do not short circuit, disassemble, heat or recharge 

a battery.

The low battery-power indicator blinks when the 
Commander SU-800’s ready-light does not come on 
within approx. 30 seconds of the power being turned 
on or after the flash has fired.

• Replace the battery.

When the SB-R200’s battery power is weak, the green 
ready-light blinks after the power has been turned on 
or after the flash has fired.

• Replace the battery.
