To assist with troubleshooting, the unit contains Crestron’s patent-pending network 
analyzer to continuously monitor the integrity of the Cresnet network for wiring faults 
and marginal system performance or other network errors. For more information on 
how to use the network analyzer, refer to the SIMPL™ Windows

 help file and use

A Lithium battery is used to power the CNMSX system clock. Under normal 
conditions, it will last for 10 years. In the event that the clock fails, only an authorized 
technician should replace it. Refer to caution statement below.  

CAUTION:  Danger of explosion if battery is incorrectly replaced.  
Replace only with the same or equivalent type recommended by the manufacturer.
