Note:
−If the test set does not directly boot up in the CPRI Testing
mode, you can access it from the Test Mode selection
window.
−It will take 40 seconds to apply the new test mode.
−If the test boots up in the CPRI Testing mode, there is no
need to change the test mode.
−If a unit is powered down in the CPRI Testing mode, the
next time it is used, it will boot up directly in CPRI Testing
mode.
