3. Set P601 battery jumper to ON and install the GCTU1A (processor Figures 1-6 and 1-10 ).
4. If applicable, install the GCDU1A (3 CO, 3 CLID and 8 DKT circuits Figure 1-11 ).
5. If applicable, install GSTU1A (standard telephone interface Figure 1-12 ).
6. If applicable, install the GETS1A 100Base-TX I/F PCB ( Figure 1-13 ).
7. If applicable, install the BSIS1A for SMDR ( Figure 1-6 ).
8. If applicable, install HPFB-6 battery/charger ( Figure 1-14 ).
9. Connect wiring ( Table 1-15 ).
10.Connect AC Adaptor to P2 of the CTX28 sub-motherboard (GMAS, Figures 1-15 and 1-16 )
