Mutual Interference Distances (Reference Only)
If Amplifier Units are connected using multidrop connections and multiple CIDRW Heads are used, the
CIDRW Heads will not process commands simultaneously. In this case, install the CIDRW Heads at
least 0.1 m apart from each other.

If CIDRW Heads in separate CIDRW systems process commands simultaneously when the CIDRW
Systems are installed close to each other, mutual interference between the Heads can result in mal-
functions. If this is a problem, install the CIDRW Heads separated at least by the distances shown in
the following illustrations.
