General instructions for GSM TX troubleshooting

Apply a RF-cable to the RF-connector to allow the transmitted signal act as normal. RF-
cable should be connected to measurement equipment or to at least a 10-dB attenuator,
otherwise the PA may be damaged.
Start Phoenix-Service-Software and establish a connection to the phone e.g. FBUS.
