Hello & Welcome to Just Answer,
Sorry to hear of the issue you are having locating the manual for this device. I have a link to the electronic (PDF) version of the manual below, which should help.
Most computers (or other devices) will display the manual on the screen when you click that link. At that point you should be able to SAVE the manual to your computer or print it, if that is your desire.
Please let me know if you have any trouble with that link.
Thanks, ***** *****
P.S. The SD/MMC card is OPTIONAL, and is mentioned in the manual in several places.
I see it has been a few days and I just wanted to follow up to see if you have any more questions concerning this issue or if the issue was resolved.
I look forward to any further questions or results that you may have.
