Connecting External Equipment
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 loss of image.
• Do not use an attenuating (built-in resistor) audio cable. 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 to avoid data
corruption.
