Cautions Regarding Batteries
This flash unit uses four AA alkaline, lithium, or nickel metal hydride batteries. Do not use any other type of
battery. The flash unit may not be able to operate correctly or demonstrate sufficient performance, or the flash
unit itself may generate heat, depending on the type of batteries used.
AA alkaline and lithium batteries themselves are not rechargeable. Also, do not dismantle the batteries. Trying
to recharge or dismantle these batteries may cause an explosion or leakage.
When changing batteries, do not mix batteries of different manufacture, type and capacity.
Do not insert the batteries with the positive (+) and negative (-) terminals the wrong way around. Incorrect
insertion may lead to an explosion or fire.
Battery performance may temporarily be hindered in low temperatures. Batteries should be kept warm in
temperatures below freezing for proper performance.
If you do not intend to use the flash unit for an extended period of time, remove the batteries. Leaving the
batteries in may cause damage to the flash unit due to leakage etc.
