3 Service 

This chapter describes how to disassemble and to service to a level 
of changing boards/parts. 

 

3.1 Disassembling 

If you have to disassemble the TT-3606E Message Terminal it is 
important, that you follow the procedure described in this section. 
Otherwise you will find it very difficult and you risk to permanently 
damage the Message Terminal.  

 

 

WARNING

 

Do not try to disassemble the 
TT-3606E Message Terminal 
yourself.  

This operation must only be 
performed by qualified service 
personnel.

 

 

 

 
The unit is assembled out of three parts: 
 
1.  Rear plate holding the floppy drive
