Adding and registering handsets

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/
El52333. Additional handsets are assigned numbers in the sequential order 
they are registered (up to 

HAnDSET 5). Each handset must be registered to 

the telephone base before use.

Before you begin registration, make 
sure the handset is out of the 
telephone base or charger and shows 
To register HS... and ...see manual, 
alternately.
Put the handset you wish to register 
on the telephone base cradle.
The 

In USE light on the telephone 

base turns on. After about 10 
seconds, the handset shows 
Registering... The handset shows 
Registered and you hear a 
confirmation tone if the registration was successful. The 

In USE light turns 

off. The handset is now registered with the telephone base.

If the registration fails, the handset displays 

Failed and then To register HS... 

and ...

see manual, alternately. Try the registration again by removing the 

handset from the telephone base and then placing it back in.

notes: 

You cannot register a handset if any other system handset is in use.
You can only register one handset to the telephone base at a time.
