be any dots on the transition edges.
• In high bandwidth pattern, there shouldn’t
be any loss of resolution and the scaling
should be correct.
• This is a sample with no visible noise.
Black & White

Connect a cable TV or RF pattern generator signal and set the RF sensitivity to 45 ~85dBµV. An
image should be displayed. If under 60dBµV, some snow noise is acceptable but there
should not be any color loss.
TV Channel Auto Scan
• The auto scan process should take less than 3 minutes.
• Pressing the “Menu” key should exit the TV channel scanning.
V-Chip & Close Caption Function Test

number 4, CC number 5, CC number 6, CC number 7, CC number 8.
• Parental Control:
• Select the “Parental Control” in OSD and enter the password “0000”. Enter the TV
rating and setting all the rating to “LOCKED”.
