NOTICE
Indicates a risk that may result in malfunction or damage to the device.
Indicates supplementary information as well as tips & advice for operations.
Installation
· After installing an IRA, confirm that it is securely fixed in place.
· Do not install the IRA or the IRDU near anything that generates infrared light, such as direct sunlight, incandescent lights,
halogen lights, inverter-type fluorescent lights, or plasma displays. Noise could be generated regardless of the effective range.
If noise is being generated, you need to install the IRAs and IRDUs in suitable locations.
· Do not place any obstacles around the IRDUs.
· Do not exceed 100 meters for the total length of cable connections.
· When installing multiple IRAs, use the same length for the total length of each of the cables from the IRAs to the IRCU/IRCUDAN.
(We recommend a difference of less than 3 m.)
· Contact our sales representative if you are going to use multiple monitor channels at the same time.
