## Long description

The Yongnuo RF-603 II Manual Flash Trigger for Canon/Nikon cameras is a compact radio wireless transmitter for off-camera flash and remote shutter release. It operates on a global 2.4GHz FSK channel, supports manual flash triggering and remote shutter release simultaneously, and is compatible with cameras and speedlites that use a standard hot shoe. The unit is battery powered (AAA cells) and has a small form factor for easy transport and handling.
Advantages
The RF-603 II offers reliable wireless triggering across a practical range (up to around 100 m in open areas) using an FSK 2.4GHz system that improves speed, distance and stability. It is compatible with a wide range of Canon and Nikon cameras and virtually any flash with a hot shoe mount. The compact dimensions and low power consumption give long operating time on standard AAA batteries, making it convenient for field use.
Suitable for
 Off-camera flash photography

How to use
Mount the transmitter or receiver unit on the camera hot shoe or the flash hot shoe as required, insert fresh AAA batteries, and set the channel/group according to your setup. For remote flash use, place a receiver under each off-camera flash and ensure each unit shares the same channel. To use the shutter release function, attach a receiver to the camera and trigger from the transmitter. Adjust the flash power manually on each speedlite; the RF-603 II controls triggering only and does not transmit TTL or automatic power settings.
Usage recommendations
Use the RF-603 II in open areas for maximum reliable range; avoid placing units near large metal objects or strong RF sources. Replace batteries before long shoots to ensure continuous operation, and verify channel/group settings during setup to prevent interference from other radio triggers.
