If the ELI system experiences problems due to the temporary disconnections, you will have to disable the ELI system through the System Manager for each temporary disconnection.

∙(MASTR II & IIe applications only) - Remove the jumper between pins 2 and 3 of the Power/Audio plug on the back panel of the GTI (see Figure 45).

∙Go on to next step if you want to put GTI units back into service one at a time (suggested for first GTI units completed), or repeat this step until several GTI units have been completed before going on to the next step (suggested for last GTI units completed).

6.System Manager (Enable Each Completed GTI):

∙Using System Manager screen 10, panel 1:4, reconfigure the “Interconnect” field to “Y” for each radio channel connected to each newly completed GTI unit.

∙Using System Manager screen 14, reconfigure the “Line Active” field to “Y” for each line number connected to each newly completed GTI unit.

∙Keep returning to the previous step until all GTI units have been completed and brought back into service.
