The Terminal contains semi-conductor components that are 
sensitive to electrostatic damage. 

Electrostatic sensitive devices should only be stored and 
transported inside electrically conductive static shielding 
bags. Fault finding and module replacement must be 
performed at “electrostatically safe work stations” where the 
work bench surface; soldering iron and the operator are all 
earthed to prevent the build up of harmful electrostatic 
charges.  

To gain service access to any of the modules, the top or bottom covers must be removed 
as follows: 

1.  Isolate the EX7100 Terminal from the incoming DC supply by removing the DC input 

wires from the rear panel terminal block. It may also be necessary to remove any 
signalling and antenna cabling. 

2.  Remove either cover as required by removing the screws. Keep all screws in a safe 

place for later replacement. 

Warning:  The VHF Duplexer module is attached to the underside of the top cover. Extra 

care must be taken when removing this cover so as not to damage the RF 
cabling connecting the duplexer to the modules within the terminal. 

The  UHF Duplexer and associated filters are attached to the outside of the 
top cover. Before disconnecting the RF cables to the rear panel, care should 
be taken to note the correct cable connection.
