Input Terminal strip C, shown on page 3-25, is to be connected to the 
Exciter. 
 
Output Terminal Strip D, shown on page 3-26, is intended to be 
connected to the Transmitter Power Amplifier and can be used for 
example where it is desired to control an ATU. The corresponding socket 
in the T5000 is only mounted and wired on special order, but a BAND 
switch wafer which can be wired to give the BAND position is always 
supplied as an integral part of the Transmitter Power Amplifier.   
 
PROM-types which can be installed in the MEMORY of /238\
