Programming and Using a Merlin Telephone
A Merlin telephone set may have extra, "blank" buttons that are programmable.  Below are the instructions for Merlin telephones.   

There are two types of sets: "Merlin" and "Merlin Legend."  Instructions specific to the "Merlin Legend" are being edited and will be posted at a later date.  

The term "direct line" as used herein refers to a telephone line with its own telephone number.  It is not part of the "Main Pool" of telephone lines.

Set the Line Pickup Order ContentsBack to Contents
When no lines are in use a red light indicates the line that will be used when you pick up the receiver.  You can then press a specific line button to place a call on that line. 
When the first line is in use, the system uses the next line in a set sequence.  You can reset that sequence using the instructions below.  One reason for resetting the sequence is to keep available the direct line you regularly use for checking voice mail.
While the telephone system typically uses "Main Pool" lines for outgoing calls and specific numbered lines for incoming calls, you may set a direct line as the default outgoing line. 
To set the pickup sequence of lines:
1. Move the switch to the P position.
2. Press [*] [*].   
3. Press the line buttons in the desired sequence order.
4. Move the switch back to the o position.
