Notes On Handling Batteries - Nikon SB-400 Manuel D'utilisation

• Take the Speedlight out once a month, insert the batteries, and fire the unit
several times to reform the capacitor.
• When the Speedlight is stored together with a desiccant, renew the desiccant
occasionally.
Operating location
• An extreme temperature change can cause condensation to form inside the
Speedlight. When exposing the Speedlight to high temperatures from very low
temperatures, or vice versa, place it inside an airtight container such as a plastic
bag. Leave it inside the container for a while before gradually exposing the
Speedlight to the outside temperature.
• Avoid exposing the Speedlight to strong magnetic or radio waves from televisions
or high voltage power transmission towers, as this may cause it to malfunction.

Notes on handling batteries

• Because flash consumes a large amount of battery power, rechargeable batteries
may not operate properly before reaching the end of their stated lifespan or the
number of charging/discharging as specified by the battery manufacturer.
• If the battery terminals become soiled, remove dirt and smudges before use, as
this may cause a malfunction.
• Battery power tends to weaken as the temperature drops. It also gradually
decreases when batteries are not used for a long time and recovers after a short
break following intensive use. Be sure to check battery power and replace the
batteries with fresh ones, if you notice any delays in the recycling time.
• Do not store batteries in locations subject to high temperatures and high
humidity.
