PCB INSTALLATION 2. PCB Installation and Startup 2-8 CPRU Installation (Figures 2-3 through 2-7) 1. Install the battery on the CPRU using the tie wrap. 2. Connect the battery to the BAT connector with the red wire up (Figure 2-3). 3. Insert the CPRU into the CPU slot in the Main Cabinet (Figure 2-4). Figure 2-3 CPRU BATTERY INSTALLATION4. Set the MOH jumper for internal/external MOH source (Figure 2-5). Use the HTVR potentiometer to adjust MOH volume. Note:When the S jumper is set for internal MOH, and an external MOH source is connected to the MISC block or to a 3ACI, external MOH is sent to trunks programmed to receive external MOH.
