This flash is used to supplement the camera's built-in flash when the
subject is too far away for proper illumination. Use the following
procedures to affix the camera and High-Power Flash to the supporting
bracket.
Please read the instructions accompanying the flash along with this

When in
The flash charge time will lengthen as the battery charge gets weaker.
Always set the power/mode switch to [OFF] when you finish using the flash.
Be careful not to touch the flash window or sensor windows with your
fingers while the flash is in use.
In outdoor settings in the daylight, the flash may not detect illumination
from the camera's built-in flash and may not fire.
The flash may fire if another flash is being used in close proximity.
The flash may not fire if there are no reflective items in its metering field.
For continuous shooting, although the flash fires for the first shot, it
does not fire for subsequent shots.
If the battery usage time has considerably diminished, wipe the battery
terminals well with a dry cloth as the terminals may be soiled with oil
from one's skin or other dirt.
If the battery is used in cold regions (0 °C /32 °F or lower), you are
recommended to carry a spare lithium battery (CR123A or DL123).
Keep the spare battery warm in your pocket until immediately before
using it, and exchange it frequently with the battery in the flash.
Leaving it in the flash could lead to the battery leaking and damaging
the flash. Remove the battery from the flash and store it in a dry and
cool location if you will not use it for extended periods.
Fasten the attachment screws securely so that they do not loosen.
Failure to do so may lead to the dropping of the camera and flash
resulting in damage to both.
