When the TETRA RADIO TEST SET is turned on, a screen appears on the display
with the initials IFR; the test set saves the data relative to the last test carried out in
the memory.
By default, the TETRA RADIO TEST SET sets itself in analog mode; to select
digital mode, press the ”SYSTEMS” key (see Fig. 7.2) to load the TETRA protocol.

Before carrying out the test, it is necessary to know which channels are set on the
terminal (setting from PRP). Even if there is more than one channel set, it is
sufficient to consider just one of them for the purposes of the test.
When the “TETRA MOBILE” key is pressed from among the keys to the right of the
display (see Fig. 7.3) and, subsequently, when the key in correspondence to “SET-
UP” is pressed (from among the keys to the left of the display), a screen appears
on the display that allows visualizing “SYSTEM PARAMETERS”; press the
“CHANNEL PLAN” key to carry out the search for the reference frequency of the
terminal being tested (see Fig. 7.4).
