Digital Spread Spectrum Technology  
utilizes a “wider frequency band“ vs. a  
“single narrow band“ used in standard digit al transmissions. The 2.4 GHz  
frequency range was recently released to commercial communications. The  
result is a more secure conversation with the clarity of digit al sound, extended  
range, and minimal interference from other cordless phones.  
TM digit al security automatically selects one of over 65,000 codes  
Random Code  
for the handset and base.  
These features enhance your phone´s security and also prevent unauthorized  
calls as a result of your phone being activated by other equipment.  
Throughout this manual, terms such as Standby and Talk Mode are used. Below  
is the terminology explanation.

Setting ring time switch  
The ring time/ toll saver switch allows you to set the number of rings the caller  
hears before the answering system plays your outgoing message. You can set the  
switch to answer after two rings or after four rings.  
Once the greeting has started, you can stop it when you pick up the call at the  
handset or base.  
If you answer at another  
phone extension and the  
greeting has started, you  
cannot stop the  
message. Wait until your  
greeting is complete  
before starting your  
conversation.  
TS  
In the  
(Toll Saver) position, the answering system picks up after two rings if  
you have new messages, and after four rings if there is none. This way, if you  
call long distance to check your messages, you can hang up after the third ring  
to avoid billing charges.

Changing the Digital Security Code  
The digit al security code is an identification code used to connect the handset  
and the base unit. Normally, setting the code is not necessary.  
The first time you charge your handset, the security code is automatically set.

In the rare situation that you suspect another cordless telephone is using the  
same security code, you can change the code.  
If the handset battery pack  
is completely discharged or  
the battery pack is  
removed, the digital  
security code will be lost.  
If this happens, a new  
security code is set  
automatically next time the  
battery pack is charged.
