XM DIGITAL SATELLITE DATA & AUDIO RECEIVER
GEX-P10XMT
- Caution
• When users complain "No Signal" is displayed, there is a possibility that an installed XM antenna
cable has shorted out only occasionally.
If there are no problems in the main tuner by a service-man checking or NTF is used, let users
confirm that the XM antenna cable has no short-circuit.
• Connect the Acc lead of the Cord Assy (CDE8009) only when IP-BUS is not connected.
For details, refer to "Important Check Points for Good Servicing".
