nCautions Regarding Batteries
l This flash unit uses 4 AA-size alkaline, lithium, or nickel metal hydride batteries. Do not use any other type of
batteries. The flash unit may not be able to operate correctly or demonstrate sufficient performance, or the flash
unit itself may generate heat, depending on the type of batteries used.
l AA-size alkaline and lithium batteries themselves are not rechargeable. Also, do not dismantle the batteries.
Trying to recharge or dismantle these batteries may cause an explosion or leakage.
l When changing batteries, do not mix batteries of different manufacturers, type and capacity.
l Do not insert the batteries with the positive (+) and negative (-) terminals the wrong way around. Incorrect
insertion may lead to an explosion or fire.
l Battery performance may temporarily be hindered in low temperatures. Batteries should be kept warm in
temperatures below freezing for proper performance.
l If you do not intend to use the flash unit for an extended period of time, remove the batteries. Leaving the
batteries in may cause damage to the flash unit due to leakage etc.

page 77) and adjust the distance to the subject, or open
the aperture further.
Even if the auto check display is blinking, the flash
output may be incorrect if the subject is too close.

Types of Batteries
This flash unit uses four AA-size batteries of the same
type, as shown below.
- Alkaline battery (LR6)
- Lithium battery (FR6)
- Nickel-Metal Hydride battery (Ni-MH)
(Nickel manganese (Ni-Mn) and nickel cadmium (Ni-
Cd) batteries cannot be used.)
l For information about recycling times and total
number of flashes, refer to “Specifications” on
page 85.
l If the indicators on the LCD panel or the ready
lamp does not light up, the batteries may be
exhausted or not inserted correctly. Verify the
orientation of the batteries or, if the indicators
and ready lamp still do not light up, replace them
with new batteries.
l If you let the flash unit fire successively using
lithium batteries, the batteries will overheat,
activating a safety circuit that temporarily
disables the flash unit. If this occurs, rest the
flash unit so that the temperature of the batteries
returns to normal.

Camera Format and Flash Coverage Angle
The AF360FGZ’s flash coverage angle can be adjusted
to match the angle of view of the lens being used,
which enables effective distribution of the flash light.
The flash coverage angle is indicated by the focal
lengths of available lenses in the LCD panel of the flash
unit, according to the preset image size (FORMAT) of
the camera.
Format setting
Firstly, set the FORMAT to match the image size
of the camera you are using.
The format size will automatically be set when
the shutter release button is pressed halfway
down when the AF360FGZ is used in
combination with the following cameras.
*ist, MZ-S, MZ-L/ZX-L/MZ-6, *ist DL2, *ist DS2,
*ist DL, *ist DS, *ist D
For other cameras, before use, set the FORMAT
to match the image size of the camera according
to the following procedure.
Slide the setting switch down (yellow dot).
Press the FORMAT button repeatedly to
display camera formats (image sizes) in the
LCD panel.
You can switch from 35mm Ý 645 Ý 67 Ý
35mm in that order.

Zoom position (Flash coverage angle) setting
Next, set the zoom (flash coverage angle) to
match the focal length of the lens you are using.
Auto Zoom (A.Zoom)
If both the camera and lens are autofocus, you can
automatically set the flash coverage angle according to
the focal length of the lens by pressing the shutter
release button of the camera halfway down.
The auto zoom function operates while the
exposure meter is operating (while information is
being displayed in the viewfinder).
If you are setting the format manually, return
the setting switch to the upper (white dot)
position.
When (M.Zoom) is displayed on the LCD
panel, press the zoom button (ZOOM)
repeatedly until (A.Zoom) is displayed.
l When the flash mode is set to auto flash, the
auto zoom function does not operate even if the
camera and lens are both autofocus. Set the
zoom manually to match the lens angle of view.
Manual Zoom (M.Zoom)
If one or both of the camera and lens are manual
focus, you must set the flash coverage angle
manually.
If you are setting the format manually, return
the setting switch to the upper (white dot)
position.
Press the zoom button (ZOOM) until the focal
length of the lens being used is displayed on
the LCD panel or if it can not be displayed
exactly one wider than the lens focal length.
The zoom position is switched in the order
shown in the diagram on page 20.
