<p>Hi Jim,<br>
I've recovered from my allergic reaction to the antibiotics doctors gave me and I'm doing well. However, I cannot say the same for my Canon F-! Motor Drive MF. After I removed it from the shipping box, I pressed the battery check button and the light came on. I then attached the drive to my Canon F-1 and it advanced one frame with a solid response --- then nothing; the battery check light still came on when depressed. I then tried the drive on 3 other Canon F-1 cameras with no response from the drive or the battery check light. I open the battery compartment and the batteries where loaded according to your previous instructions. I then removed the batteries the drive shipped with and installed a fresh set of Duracell Alkaline batteries in the same configuration, but no response from the battery check light and no response from the motor drive when tried to take a picture. Can you help?</p>
