Hi yes you can, I am not sure if you have Adobe PDF reader installed so you can view the instruction manual, it has a great word search function, I used 'wireless' to find this information on page 101;
Performing wireless flash shooting
With a flash that has a wireless shooting function (sold separately), you can shoot with the flash without a cord, even when the flash is not attached to the camera. By changing the position of the flash, you can shoot an image with a three dimensional feel by highlighting the contrast of light and shadow on the subject. For the actual steps of shooting, refer to the operating instructions of the flash.
1 Attach the wireless flash to the Auto-lock Accessory shoe and turn both the camera and the flash on.
2 Fn button (Flash Mode) (Wireless)
3 Remove the wireless flash from the Auto-lock Accessory shoe and pop up the built-in flash.
• If you perform a test fire of the flash, press the AEL button.
Notes
• The camera cannot carry out the wireless lighting ratio control.
• Turn off the wireless flash mode after wireless flash shooting. If the built-in flash is used while the wireless flash mode is still active, inaccurate flash exposures will result.
• Change the channel of the external flash when another photographer is using a wireless flash nearby and his/her built-in flash light causes your external flash to fire. To change the channel of the external flash, refer to the operating instructions supplied with it.
