Your telephone system can support up to five handsets. The handsets
provided within your product package are already registered as HANDSET 1,
and so forth. You can purchase additional handset AT&T EL50003 or AT&T
EL50013 to expand your telephone system. EL50003 (silver) is for use with
EL52103/EL52203/EL52253/EL52303/EL52353/EL52403/EL52503.
EL50013 (champagne) is for use with EL52113/EL52213/EL52313/

they are registered (up to HANDSET 5). Each handset must be registered to
the telephone base before use.
