InfinityBoard Assembly Instruction
Connecting Cables
NOTE: Do not connect or disconnect cables when turning on the monitor's main power or other
external equipment's power as this may result in a loss of image.
NOTE: Do not use an attenuating (built-in resistor) audio cable. Use an audio cable without a built-in
resistor. Using an audio cable with a built-in resistor will lower the sound level.
Before making connections:
• Turn off the device's power before connecting it to the monitor.
• Refer to the device's user manual for available connection types and instructions for the device.
• We recommend turning off the monitor's main power before connecting or disconnecting a USB
storage device or a microSD memory card to avoid data corruption.
