CTS55 Getting Started With Autotest

Explanations:
When the mobile has synchronised via the broadcast channel (SERVICE is indicated on the mobile’s
display), the user is requested to make a call from the mobile. At this point the user may dial any
number. It is however advisable to choose a number that contains all 10 digits in order to verify the
proper functioning of all keys. CTS shows the dialled number on the display, so the user can see at a
glance whether all numeric keys are in functioning correctly. When the speech link is successfully set
up, CTS terminates the test step with a " ".
The average transmitting power of the mobile is measured at three levels. The test will be terminated
with "pass" if the results are within their respective tolerance ranges. Otherwise the message "fail"
will appear.
Each GSM850/GSM/PCN/PCS mobile is capable of measuring its received level (RxLev) as well as
the quality of the received signal (RxQual). The values for the two parameters are continuously
transmitted to the test unit. In this "sensitivity" measurement, the signal is sent to the mobile on the
speech channel at a selectable transmit level and the values obtained for RxLev and RxQual are
evaluated. In general, the value transmitted for RxQual is increasing with decreasing transmitting
level. The lower the transmitted RxQual value, the higher is the "sensitivity" of the mobile.
The test will be terminated with "pass" if the results for RxLev and RxQual are within their respective
tolerances.
