1 Open the cover.
• Slide the lock-release lever to the left
2
as shown in the illustration, slide the
cover down, then open the battery
compartment cover.
Install the batteries.
• Make sure the "+" and "-" electrical
contacts are correctly oriented as
shown
in the battery compartment.
• The grooves on the side surfaces
of
the battery compartment indicate "-".
This
is convenient when replacing the
batteries in a dark place.
3 Close the cover.
• C1ose the battery compartment cover
and slide it up.
~ When it clicks in place, the battery
compartment cover
is locked.
~CAUTION
• Do not use "AAIR6 lithium batteries".
Note that certain "AA/R6 lithium batteries" may become extremely hot in rare
cases during use. Due to safety reasons, do not use "AA/R6 lithium batteries".
• When performing continuous flash, do not touch the flash unit,
batteries, or the area near the battery compartment.
When continuous flash or modeling flash is repeatedly fired at short
intervals, do not touch the flash unit, batteries,
or the area near the battery
compartment. The flash unit, batteries, and area near the battery
compartment may become hot, resulting
in the risk of burn.
• Do not allow the product to maintain contact with the same area of
skin for extended periods of time during use.
12
This may result in low-temperature contact burns, including skin redness
and blistering, even if the product does not feel hot. The use
of a tripod or
similar equipment is recommended when using the product
in hot places
and for people with circulation problems or less sensitive skin.

The Quick flash function enables flash photography when the flash-
ready lamp
is
lit green (before the flash is fully charged). Quick flash
is
available regardless
of
the camera's drive mode setting. Although the
flash output will be approx. 1/2 to 1/6
of
the full output, it
is
useful for
shooting with a shorter firing interval.
During manual flash shooting, this function
is
available when the flash
output
is
set to 1/4 or smaller. Note that you cannot use Quick flash with
FEB or during wireless multiple flash shooting.
