.

2. Input a 4-digit PIN using the numerical keys (0-9), and press SET to        

 confirm. If you want to delete the code, press DEL.

3. Set the telephone in DND state. (Please refer to ‘Ring Tone’ on page 11) 
 

How does it work?
When the phone is set to the DND mode, it will not ring when a call comes 

through. However, the caller will hear the usual ring tone (when the line 

gets through) a couple of times and then a short ‘

di

’ sound. At this point, 

the caller should key in the secret code. Once the caller keys in the correct 

code, the unit will ring. 

Press   or pick up the handset to have the conversation with the caller.         

If the caller keys in the wrong code, he/she will have to call again and key 

in the correct secret code.

#

This function is useful only when the unit is in the DND mode (ringer 

is set to OFF). The caller must know the secret code in order to dial 

through the line.

The secret code, when entered by the caller, enables the phone to ring 

even though it is in the DND mode.
