NOTE: 

*   

When  JMP23 is shorted, it will RESET the MFJ-1278B.  This means that all 

parameters will be reset to the default values.  This is the same as removing the bbRAM 
battery except it is much quicker.

MFJ offers an optional Real-time clock module (MFJ-43) that can be installed on 

the MFJ-1278B mother board.  This clock keep the MFJ-1278B clock running all the time. 
You will not have to reset the clock everytime you turn the MFJ-1278B on. 
 
***  

When these jumpers (JMP E, JMP F, JMP G, JMP H) are removed the MFJ-1278B 

will operate European RTTY tone when the VB modem is selected.  All four jumpers must 
be removed to operate European RTTY. 

The MFJ-1278B provides the user with a built-in Parallel Printer Port.  The user can use the
