Godox X1C - TTL Wireless Flash Trigger Manual

Foreword

Thanks for your purchase of this X1C TTL wireless flash trigger.
This TTL wireless flash trigger can be used with a transmitter and one or more receivers for studio flash, speedlite, and camera shutter. Featuring multi-channel triggering, stable signal transmission, and sensitive reaction, it gives photographers unparalleled flexibility and control over their strobist setups. The flash trigger applies to hotshoe-mounted Canon EOS series cameras, as well as the cameras which have PC sync sockets.
With X1C wireless flash trigger, high speed synchronization is available for most of camera flashes in the market which support E-TTL II. The max flash synchronization speed is up to 1/8000s *.
*: 1/8000s is achievable when the camera has a max camera shutter speed of 1/8000s. 1/8000s is not achievable because some models of Canon EOS cameras have a max camera shutter speed of only 1/4000s.

Battery

• Installing Batteries
  As shown in the illustration, slide the battery compartment lid of the transmitter and receiver and insert two AA batteries (sold separately)separately.
  
• Low Battery Indication
  When the battery power (2 AA batteries <2.0V) gets low,
  Status Indicator Lamp blinks quickly (blink cycle=0.5s).
  Please replace new batteries, as low power leads to no flash or flash missing in case of long distance.

3. Press the camera shutter and use the PC Sync Socket's signal to control the flash.
4. PC Sync Socket can also be set as output. Long press the <CH/OK> Button of the transmitter until <Fn> is displayed on the panel. Then, set the value of C.Fn-03 to ou, and the PC Sync Socket is under output mode.

Setting the Transmitter

Power Switch

Slide the Power Switch to ON, and the device is on and Status Indicator Lamp will not blink.
Note: In order to avoid power consumption, turn off the transmitter when not in use.

Power Switch of AF Assist Beam

Slide the power switch to ON, and the AF lighting is allowed to output.

Channel Setting

1. Short press the <CH/OK> Button until the channel amount blinks.
2. Turn the Select Dial to choose the appropriate channel. Press the <CH/OK> Button again to confirm the setting.
3. This flash trigger contains 32 channels which can be changed from 1 to 32. Set the transmitter and the receiver to the same channel before usage.

Mode Setting

1. Short press the <MODE> Button, and the mode of the current group will change.
   
2. To NON-GR grouping mode, all the groups' modes will be changed simultaneously by the order of TTL/M/Multi, in accordance with Ratio flash mode. To GR grouping mode, only the current group's mode will be changed by the order of TTL/M/--.

Current Group Settings

1. Short press the <GR> Button to set the current group.
   
2. The current group settings will blink and turn the Select Dial to change the settings.
3. When the current group is in the M mode, the power output value is changeable from 1/1 full power to Min.[Note 1] power in 0.3 stop increments. When the current group is in the TTL mode, the FEC amount is changeable from -3 to 3 in 0.3 stop increments. When the current group is in the -- mode (flash off), the amounts will not change.
4. Short press the <GR> Button again to confirm the setting.

[Note 1]
Min. refers to the minimum power output value that can be set in M/Multi mode.
X1C's minimum power output value is 1/128 for most of camera flashes. However, the value can change to 1/256 when using in combination with Godox strong power flashes e.g. AD600, etc.

Caring for Device

• 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.

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.
5. No or is displayed on the camera viewfinder, though the camera is mounted on the transmitter and the power switch is turned on. This is resulted from unusual working of the transmitter. Check and make sure the flash trigger is well connected to the camera through Hot Shoe Camera Connection, then power the Transmitter on again.
