Switching Between the Handset and the Speakerphone 

 To switch a call between the 

Handset

 and the 

Speakerphone

 during a conversation: 

1.  While talking on the handset, press the 

Speaker

 button to activate the speakerphone.  

The call can now be heard from the speakerphone. 

2.  While talking on the speakerphone, simply lift up the handset and the call will be 

transferred to the handset and will no longer be heard on the speakerphone. 

3.  Hang up the handset.  Hanging up the handset will 

not

 disconnect the call when the 

Speakerphone is activated.  You have to press the 

Speaker

  button to disconnect the 

call.  

4.  If the speakerphone is not activated, simply hang up the handset and the call will be 

disconnected. 

Enabling Amplification for Handset Receiver 

If you press the 

Amp

 button during a call, phone will toggle between amplification on and 

off mode. If you adjust frequency-specific tone amplification in the amplification on mode, 
new settings replace the old ones automatically. The amplification settings will be reset 
back to the normal volume automatically after the handset is hanged off or on-hook. 

Redialing 

You can redial the last number you called with just one touch of the 

Redial

 button.  This 

lets you easily redial the same number again if the line was busy.   

1.  Pick up the handset or press the 

Speaker

 button and listen for a dial tone. 

2. Press 

the 

Redial

 button and the last number you dialed will be shown on the display 

and will be automatically dialed. 

Putting a Call on Hold 

The 

Hold

 button allows you to place a call on "HOLD" without disconnecting the call.  

When a call is on hold, you may hang up the handset without disconnecting the call. 

1. Press 

the 

Hold

 button and the current call will be placed on hold.  If you were talking 

with the handset, you can then place the handset back in the handset cradle without 
disconnecting the call.  If you were talking with the speakerphone, the call is placed on 
hold.  The red Hold light inside the 

Hold

 button is lit when a call is on hold. 

2.  To continue the conversation, pick up the handset or press the 

Speaker

 button. 

Muting a Call 

In addition to putting a call on hold, muting a call is a good way to mute the phone so that 
the person on the other end of the line will not hear what you are saying.  You can 
continue to hear the person on the other end. 
1. Press 

the 

Mute

 button to mute the call.  While a call is muted, the mute light inside 

the 

Mute

 button is lit.
