Editing Procedure 

Step 1. Press and hold the ENTER key for 3 seconds to enter Main Menu: 

If a password is required, enter the correct key code. The key code is entered by
pressing the RIGHT-DOWN-UP-DOWN keys in sequence.

The system will return to the view menu if no key is pressed for 10 minutes.

Step 2. Navigating the menu with the UP and DOWN keys. 

Once the selected menu is highlighted, press 

ENTER
