Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Is it the wireless passphrase for your camera's WiFi connection, that you want to reset, or change?
(As for a manual, I may be able to find an online source for a manual for your camera, free of charge, in PDF format.)
(I regret that I am not able to offer Live Phone Call service at this time; However, your request is still open to other Experts in this category, and one of them may pick up on it at any time.)
I am Opting Out, since that lets you wait for someone to take up the request for Phone Call service... and it relieves you of typing! Please be patient, and I'm sure someone else here will help you soon enough (since I cannot.)
Thank you for your patience, meanwhile.
