LED Light
The built-in LED light provides continuous illumination. This
is particularly useful when shooting video, as a modeling
light, or as an AF assist beam (with Live View). The LED
light can provide up to 3.5 hours of illumination with four
fully-charged AA batteries. It will automatically shut off after
60 minutes of idle use to conserve battery power. If battery
power is low the LED Light will not turn on, even if the flash
ready light is lit, in which case you should replace the bat-
teries.
Manual Flash Set-up
You can manually adjust the flash output from full 1/1
to 1/64 power by using the External Flash Menu on
th
compatible EOS SLRs*. The lower the flash output, the
shorter the maximum range and the closer the minimum
distance. The higher the flash output, the greater the
maximum range. Use a hand-held flash meter or trial-and-
error to determine the correct aperture for a given flash-to-
subject distance. Once set, the exposure will remain the
same as long as the distance and flash power level remain
the same.
1. Press the camera Menu button*.
2. Select the first Shooting Menu (first camera icon on the
left).
3. Select [Flash control] or [External Speedlite control].
4. Select [External flash func. setting]. Press Set.
5. Scroll down to Manual flash. Press Set.
6. Select Flash output. Press Set.
7. Select the flash output you want. Press Set.

Wireless E-TTL Flash Operation
The "Slave" function allows the flash to be triggered
wirelessly when used off-camera with an EOS DSLR or
Speedlite with master flash function. The slave flash must
be positioned off-camera and must be within a range of 33
feet (10 meters) from the master flash unit.
The 320EX can be assigned to any one of four channels
and three groups. The channel setting (1, 2, 3 or 4) must
match the channel setting on the camera or master unit.
The group setting (A, B or C) is important only if you
are using more than one Speedlite, in which case you
must assign them to the same group if you want equally
distributed output or different groups if you want unequally
distributed (ratio) output.
1. Set the camera, ST-E2 transmitter or 580EX II
Speedlite as the master unit.
2. Set the 320EX as the slave unit by moving the power
switch to <SLAVE>.
3. Set the transmission channel to the same channel as
the master unit.
4. Set the firing group (if using more than one slave).
5. Attach the 320EX to the mini-stand (provided with
the flash case) and position the flash. When outdoors
you must have the wireless sensor aimed toward the
master unit. When indoors the sensor will usually
react to reflections from nearby walls.
6. Release the shutter.

Wireless Shutter Release
The flash release function uses the 320EX's built-in
infrared transmitter to trigger compatible cameras* with a
2-second delay. You can choose whether to use the 320EX
as a wireless trigger only or whether to also use it as a
wirelessly triggered slave flash.
To trigger camera only:
1. Set the camera to Remote/Self-Timer mode.
2. Set the 320EX power switch to <ON>
3. Point the remote control transmitter on the front of
the 320EX toward the camera, then press the remote
release button. The shutter will release two seconds
later. The 320EX will not fire.
To trigger camera + wireless flash:
1. The camera must have a "master unit" triggering
device for Wireless E-TTL flash mounted and active..
2. Set the 320EX power switch to <SLAVE>.
4. Set the camera to Remote/Self-Timer mode.
3. Point the remote control transmitter toward the front of
the camera, then press the remote release button. The
camera will fire two seconds later, which allows time
to reposition the 320EX to illuminate the subject. The
master flash will trigger the 320EX you're holding.
Auto Power Off
The 320EX will automatically shut off after 90 seconds of
idle use to save battery power. Press the camera's shutter
button to turn the unit on again. When using the 320EX as
a wireless slave you may wish to cancel the auto power off
function by pressing the [✻] button on your camera.
AF-Assist Beam
To facilitate autofocus for dark scenes, the flash may fire
repeatedly when you press the camera's shutter button
halfway. Its maximum AF-Assist range is approximately
2.3 - 13.1 ft., depending on the ISO setting and maximum
aperture of your lens.
