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.

1. Confirming the Size of the Room Intended for Installation
Checkpoints ① Width, length, ceiling height, existence of windows, etc.
② Does construction of the ceiling allow for installation (ceiling surface,
existence of space above ceiling)
1.1 Names of IRA Parts
① Power LED
Lights when the power to
the IRCU is on, after wiring is
complete.
② Hook for mounting
Use to mount on the mounting
bracket (included accessory).
③ BNC connector
· BNC cables are not included
accessories.

NOTICE
· Infrared transmissions cannot reach the IRA if they are hidden or blocked by users.
· Install multiple IRAs so they can be seen from the IRDUs
· Do not cover the infrared transmitter with your hand or anything else.

3. Confirming the Operating Arrangements
Checkpoints ① Confirm operating format: U shape, square shape, school format, etc.
② Distance between and orientation of IRDUs and IRAs
· Be sure to install an IRA in front of the IRDUs so the IRDUs can transmit.
· For specific installation positions, contact our sales representative.
