Caution: When installing this EMB-B75B motherboard, care should be taken to avoid
static discharges that can damage the motherboard. The motherboard installation should
be done on a static dissipative mat along with a grounding wrist strap.
Removing the Motherboard and ON/OFF reset board
1. Turn the jukebox off and unplug the power cord from the wall outlet.
2. Open the jukebox door and disconnect all the harnessing to the Computer Core. Note where
the cables plug into the Computer Core Assembly for later reinstallation. Remove the
Computer Core from the jukebox.
3. Rowe has six major Computer Cores as shown in Figure 2. Each Core has slightly different
variations (fans, lights, etc.) depending on your jukebox model. It is important to note these
variations and ensure they are connected after the motherboard installation.

4. Remove all necessary components and covers to access the motherboard. Unplug and remove
all ribbon cables from the motherboard. Disconnect all of the ATX power supply connections
and the IDE Cable from the hard drive. Remove the modem card and its PCI cover (if
present) from the motherboard; they will not be reused. Replacement PCI Covers (Items #5
and #6) are provided in this kit.
5. Remove the old ON/OFF reset board (340524XX) and the DB9 cable assembly from its
mounting bracket; they will not be reused. Save the mounting bracket and hardware for later
use.
6. Remove the seven screws that secure the motherboard to the core chassis. The motherboard
and the front panel will not be reused; save the screws for later use.
