2.3 MU-9X15 Mounting
Caution!
Disable the machine on which the receiver is to be
attached before installation to avoid injury.
Use the configuration diagrams supplied by Cervis to guide you in mounting the receiver and
connecting your wire harness. Mounting of the receiver is left much to your discretion with the
following guidelines:
Make sure that the configuration diagrams supplied with the system are available. Keep
them where they can be easily accessed when needed.
Mount the receiver away from any intense radio or electric disturbance sources.
Mount the receiver where there is enough room to make wiring harness terminations.
Make sure the mount is secure.
The external antenna must be connected only as recommended by Cervis with parts
recommended by Cervis.
Under no circumstances can a signal amplifier be used.
Mount such that the unit antenna is in view of the operator. Apply an antenna extension
cable if needed. Cervis optional extension cables are 3ft. (J5-07), 10ft. (J5-02), or 25ft. (J5-
13). See Figure 6.
