• 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.
