Can you please go through the operation manual to check whether anything is mentioned about resetting using a default password key?

Unconfig switch all

This method works only if you have access to the system when its turned on because this method requires MS DOS. Open Command Prompt from Programs menu and provide following commands one bye one:
debug o 70 2E o 71 FF
quit NOTE: The first character in the above commands is Englishalphabet "o" and not the number 0.

First,you can try this method.Start system and press F8 key when Windows is starting up. Then select Safe Mode with Command Prompt and enter. Choose Administrator,the default password may be blank if you don't set the default administrator password before.Then you will enter into doc Command as following.
Type " net user net user xxx 12345 /add " (xxx is the locked account name and 123456 is the new password set on this account).Then you will see the Command Completed Successfully.
Then this method can fully help you remove the administrator password,i highly suggest you this one.
1. Login to a computer that can link to Internet. Download windows Password key from http://www.lostwindowspassword.com and install it on that PC. Note that: there is a .ISO file. Burn the .ISO file to a CD or a USB flash drive.
2. Insert the newly created CD/USB drive to the locked computer.
3. Reboot the locked computer and press'F2'or'Delete'to enter your BIOS setup and then followed the process of instructions. Just a few steps, the old password was removed.

SD and SDHC cards have a slide switch along one edge. The position farthest from the contacts locks the card, protecting it from writes. The position nearest the contacts unlocks the card. If the switch is already in the proper position, slide it fully the other way and then back again.

Indeed, I did the same thing.... I did find the answer in the manual!
Here's a copy of it (pg 23):

Set the command mode for the remote so it matches
the command mode for the recorder you set above.
1 Hold down ENTER
2 While holding down ENTER, enter the
command mode code number using the
number buttons.
Command Mode Code number
DVD1 number button 1
DVD2 number button 2
DVD3 number button 3
3 Hold down both the number buttons and
ENTER at the same time for more than 3
seconds.
4 Let up, press RETURN, all done!
