Many of the RCA 25450 Phone System functions (including sound, phone settings, registration, system settings and line dedicate) can be customized to meet individual user requirements. To allow for a quick startup, these functions may have default settings that are factory set when a Base Unit and Cordless Handset(s) are purchased
as a system. Most of these functions are accessed by pressing the 
soft button on the Base Unit or Cordless Handset.
NOTE: Some settings listed below are described in other sections of this User’s Guide.
