To check the function, you may now open a time window for testing and check the GSM signal quality on the
EK280 display (see Section 7.1.2.2 "Checking GSM field strength", page 48) and for a test call off with enSuite
(see Section 7.1.2.3. Retrieving data with enSuite", page 49).
If using an external address, the position of the antenna should be chosen in such a way that the
best possible reception is achieved.
