VIEWSONIC EXES-2000 - Manual (Page 23)

The CC unit incorporates a CMOS IC. Particular care is to be taken about its damage static electricity causes
when you make switch settings.
Lithium battery is used for a memory backup battery BAT-1, which maintains the important data stored in a
memory during power outage. A life span of the lithium battery largely varies depending on ambient
temperature and a space of time that the exchange was used. To be on a safe side, therefore, we suggest that
the battery be replaced every 3 years. Be sure to set up No. 24 programming again after its replacement.
1 Dial operations to select functions
(*1) General purpose control and PA paging are alternative functions. So dialing as to select general
purpose control will automatically deprive the system of the PA paging function.
(*2) Depress dial keys as shown in a parenthesis when the "tie-lined" exchange is the
EX-610/620/630.
(*3) Making initial settings puts the system in the "not available" mode.
