General instructions for transmitter (TX) Troubleshooting
Please note the following before performing transmitter tests:
• TX troubleshooting requires TX operation.
• Do not transmit on frequencies that are in use!
• The transmitter can be controlled in local mode for diagnostic purposes.
• Remember that re-tuning is not a fix! Phones are tuned correctly in production
Note:
Never activate the CDMA transmitter without a proper antenna load. Always connect a
50
Ω
load to the RF connector (antenna, RF-measurement equipment or at least a 2 W
dummy load); otherwise the CDMA Power amplifier (PA) may be damaged.
