The security code is set to ‘‘HP003633’’* or ‘‘HP003634’’** when the power supply is shipped from the factory. The security code is stored in non-volatile memory and does not change when the power has been off or after a remote interface reset.

•To enter the security code from the front panel, enter only the last six digits.

•To enter the security code from the remote interface, you may enter up to 12 characters.

Use the resolution selection keys to move left or right between digits. Use the knob to change the digits. Notice that the security code may be different if the security code has been changed from the default setting.
