Nikon SB-400 Manuel D'utilisation page 13

Usable batteries
Install two AA-type penlight batteries (1.5V or lower) of any of these types:
Alkaline-manganese (1.5V), Lithium (1.5V), Oxyride (1.5V), Ni-MH
[Nickel Metal Hydride (rechargeable), (1.2V)]
• When replacing batteries, replace both with fresh ones of the same brand.
• High-power manganese batteries are not recommended for use with the SB-400.
• Depending on battery specifications, when the Lithium 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.
Replacing/recharging the batteries
When the battery power becomes low, the Ready-light blinks at 2 Hz
(twice in a second) for approx. 40 seconds. Replace or recharge batteries.
Standby function to conserve battery power
• If the SB-400 and the camera are not used for more than 40 seconds, the standby
function activates and automatically turns the SB-400 off to conserve battery
power (it goes into the standby mode).
• When the SB-400 is mounted on a camera, the SB-400 automatically turns off
when the camera goes into standby mode after the camera's exposure meter is
switched off.
• When in the standby mode, the SB-400 turns back on again when the [ON/OFF]
switch is [ON], or the camera's shutter release button is lightly pressed.
