Cable Standard:

Cable’s quality directly affect the video signal transmission quality. in order to achieve good quality signal transmission, recommend use standard cat 5e/6 or better utp cable.

Warm Tip:

The cable quality, could use “multimeter” check one pcs twist pair wire’s DC impedance. normally request dc impedance<18Ω/100m, that means < 54Ω/carton.

Dial Switch

• Dial Switch use for adjust contrast. Different compound mode makes different level of contrast.
• Level 1 (Lowest) : “1” “2” “3” “4” All The Tap Position Turn Up
