Tips on Speedlight Care and Reference Information Notes on Batteries • The large amounts of current used by the Speedlight may result in rechargeable batteries becoming unusable before reaching the manufacturer's stated recharge/discharge limit. • When replacing the batteries, turn the product off and insert the replacement batteries in the correct orientation. • Dirt on the battery terminals can interrupt the flow of current. Clean dirt from the terminals before inserting the batteries. • After being fired multiple times in quick succession, the Speedlight may stop operating to allow the batteries to cool depending on battery specifications. Normal operation can be resumed once the batteries have cooled sufficiently. • Batteries tend to lose capacity at low temperatures, recover lost voltage when allowed to rest, and slowly discharge when not in use. Be sure to check the battery level before use and replace the batteries before they are fully discharged. • Do not store batteries in locations subject to high temperatures or high humidity. • For information on handling and recharging rechargeable batteries, see the documentation provided by the manufacturers of the batteries and the battery charger. • Do not attempt to recharge non-rechargeable batteries. Failure to observe this precaution could cause the batteries to rupture.
