Attentions

1.

Unable to trigger flash or camera shutter. Make sure batteries are installed 
correctly and Power Switch is turned on. Check if the transmitter and the receiver
are set to the same channel, if the hotshoe mount or connection cable is well 
connected, or if the flash triggers are set to the correct mode. 

2.

Camera shoots but does not focus. Check if the focus mode of the camera or lens
is set to MF. If so, set it to AF.

3.

Signal disturbance or shooting interference. Change a different channel on the 
device.

4.

Operating distance limited or flash missing. Check if batteries are exhausted. If so,
change them.

The Reason & Solution of Not Triggering in 

PIXAPRO

 2.4G Wireless

Avoid sudden drops.

 The device may fail to work after strong shocks, impacts, or 

excess stress. 

Keep dry.

 The product isn’t water-proof. Malfunction, rust, and corrosion may occur 

and go beyond repair if soaked in water or exposed to high humidity. 

Avoid sudden temperature changes.

 Condensation happens if sudden 

temperature changes such as the circumstance when taking the transceiver out of a 
building with higher temperature to outside in winter. Please put the transceiver in a 
handbag or plastic bag beforehand.

Keep away from strong magnetic field.

 The strong static or magnetic field 

produced by devices such as radio transmitters leads to malfunction. 

Caring for Flash Trigger

4. Whether the flash trigger and the receiver end equipment are in the low

battery states or not

 Please replace the battery(the flash trigger is recommended to use 1.5V 

disposable alkaline battery).

1.

Disturbed by the 2.4G signal in outer environment (e.g. wireless base
station, 2.4G wifi router, Bluetooth, etc.)

To adjust the channel CH setting on the flash trigger (add 10+ channels) and 

use the channel which is not disturbed. Or turn off the other 2.4G equipment in 

working.

2.

Please make sure that whether the flash has finished its recycle or caught up 
with the continuous shooting speed or not(the flash ready indicator is 
lighten) and the flash is not under the state of over-heat protection or other

 

abnormal situation.

 Please downgrade the flash power output. If the flash is in TTL mode, please try 

to change it to M mode(a preflash is needed in TTL mode).

3.

Whether the distance between the flash trigger and the flash is too close or
not

 Please turn on the “close distance wireless mode” on the flash trigger (

0.5m):

 Please set

 

the C.Fn-DIST to 0-30m.
