higher sync speed, this function is more applicable to strobe
flashes whose flash duration is longer. (PC port output only)

1. Connect the receiver to flash via PC port and it may
needs setting at manual full-power flash output (1/1).

2 . Use manual exposure or shutter-priority mode, set the shutter

sync as hi-speed sync, the maximum shutter sync speeds can
reach to 1/8000s. Take photos and check whether the photos
are synchronous , it may see gradations or variations in the
photos, results depend on the camera and flash.

Caution! Do not connect to the PC
port any flash requiring trigger
voltage more than 300V, or the
transceiver may be damaged.

AF Assist Beam Emitter

When using AF under low-light, the

built-in AF-assist beam emitter of the
transmitter will be emitted automatically
to make it easier to autofocus, and the
flash on the transmitter which support AF
assist beam emitter function can also be
emitted at the same time.

References

※ It needs using single autofocus for the lens.
※ It needs enabled the AF assist beam function of camera

(flash) by custom functions setting. Can also disable this
function by custom functions setting(C.Fn8).

※ Both the receiver and the off-camera flash on the receiver

will not be emitted.

Feedback Function of the AF Assist Beam Emitter

24

※ Only when the flash which supports assist beam emitter

function is set in the receiver and the assist beam emitter is
available, can this function be used.

※ Install the receiver on the camera and set the assist beam

firing as disable via external flash custom function setting
camera menu to disable this function(sets will be saved).

※ If parameter which the flash doesn’t support had been set

(such as hi-speed sync), this function will be abnormal.

When the off-camera setting

About the Max Sync Speed

It needs the camera and flash both support hi-speed sync, and
the max sync speed is 1/8000s or 1/4000s. When using the hot
shoe flash which doesn’t support hi-speed sync, the max sync
speed is 1/250s or lower.

About Automatic Saving Function

The transceiver will automatically save the sets such as channel,
receiving group, AF assist beam. In the TTL set, some parameters
will not be saved, such as the set of fire ratio etc.

Applications

Troubleshooting

1. Fail to power on or automatic shutdown:

● The battery is loaded inversely or exhausted; it will power off

automatically when the battery is going to be exhausted in
case of being over discharged.

▲ Install the battery according to the correct direction the

battery compartment indicates and ensure the battery is full
and restart the power (refer to page 8).

2. The flash doesn't fire

Ensure the power of all equipments are full, the connection
among the transceiver, camera and the flash is reliable;
whether the indicator is set in the same channels and
controllable groups. Flashes recycle process, entering in the
state of overheating protection, ongoing zoom adjustment,
the flash enters into sleep status etc. may makes the flash
doesn't fire . Ensure the flash is in ready state, use the [Test]
button test the flash before using.

3. Fail to enable the 2nd curtain sync:

● That’s because the restriction of camera menu.

▲ It shall set the wireless function disabled if needs using the

2nd curtain sync.

4. Can't access into the external flash function menu or the

menu is displayed abnormally:

● The transmitter is not installed right , the contacts of the hot

shoe is stained or the power of the battery is exhausted.

▲ Reinstall the transmitter and clean the contacts ,

batteries.

5. The assist beam emitter doesn't work :

Refer to page 24.

6. The on-top flash doesn't fire：

Enabled the master flash via the wireless function setting.

replace the

26

7. Can't set the flash zoom via camera menu:

When the mix control mode has been set in the transmitter
(p.21) or zoom locking has been set in the receiver (p.15),
zoom can't be set via camera menu. Zoom setting of the on­top flash needs to be set separately(p.17).

8. Fail to set channel 5, 6, 7 via camera menu:

This is caused by the camera restriction and it can only set the
channel 1-4 in via camera menu, while other channels can be
set via channel button.
