To reset the DVR password for the Viewtech MHDV04P, use the Reset switch to return all settings to factory defaults. Follow these steps:

1. Turn off the DVR.
2. Insert a straightened paperclip into the reset hole.
3. While holding the reset switch, turn the DVR back on.
4. Continue holding until the DVR begins initializing.

This will reset the password to the factory default, which is 'none'. You can then log in without a password and set a new one under MENU > SYSTEM > User.
