Phoenix self test troubleshooting

Context
Always start the troubleshooting procedure by running the Phoenix self tests. If a test fails, please follow the
diagram below.
If the phone is dead and you cannot perform the self tests, go to
(page 4–7) in chapter 3, Baseband troubleshooting and manual tuning guide.
Note: Self tests are recommended to be made when phone is in jig and a 50Ω load connected to
the RF connector. Otherwise power tests may fail depending on antenna load
