Foreword
This Amendment to ETS 300 133-5 (1992) has been produced by the Paging Systems (PS) Technical
Committee of the European Telecommunications Standards Institute (ETSI).
This Amendment contains changes to the following pages of Edition 1 of ETS 300 133-5:
9, 12, 13, 14, 18, 24, 30, 32, 33, 34, 36 and 39.
Amendments
Page 9, amendment to Clause 3
Add the following definition after the definition of "Batch number":
Channel switching: receiver is receiving system information on one channel and does not find its initial
address in the address partition. It then switches channels and prepares to receive signals in its batch on
that channel.
Page 12, amendment to subclause 6.1
Replace bullet items i) to v) with the following bullet items:
i) average useable sensitivity under normal conditions: 25 dBμV/m;
ii) sensitivity under normal conditions but with a transmitter frequency offset of ± 200 Hz shall be the
reference figure minus 3 dB;
iii) sensitivity under channel switching conditions shall be the reference figure minus 3 dB;
iv) maximum variation in sensitivity under extreme temperature and voltage conditions: + 6 dB;
v) maximum variation in sensitivity under extreme temperature and voltage conditions with a
transmitter frequency offset of ± 200 Hz shall be + 6 dB;
Page 12, amendment to subclause 6.1
Replace bullet item xiii) with the following bullet item:
xiii) maximum variation in sensitivity for combined multipath and quasi synchronous
transmissions: 15 dB;

Page 13, amendment to subclause 6.2
Replace bullet items c), d) and l) with the following bullet items:
c) the measurement of the sensitivity shall be repeated for all six receivers under normal and extreme
conditions in the test fixture according to Annex A, Clause A.1;
d) the sensitivity on the lowest and highest ERMES frequencies shall be measured for all six receivers;
l) channel switching: The sensitivity shall be measured with the following test signal: A batch shall be
transmitted consisting of 139 initial addresses numerically higher than the initial address of the
receiver under test. This shall be immediately followed by the test message shown in subclause
8.1.1 transmitted on the appropriate channel (see ETS 300 133-4 [1], figure 2). Both shall be of the
same batch type (i.e. same batch number), within the same subsequence and neither shall contain
the home operator identity.
Page 14, amendment to subclause 7.3.3
Add the following paragraph at the end of subclause 7.3.3:
As an optional feature, the pager may also include any additional character sets, as defined in
ETS 300 133-4 [1].
Page 18, amendment to subclause 8.1.5
In the first paragraph, replace the words ".i.Initial Address; (IA)" by "Initial Address (IA)"
Page 24, amendment to subclause 9.2
Add the following paragraph after the existing paragraph of subclause 9.2:
The receiver shall be sent a transmission as specified in subclause 8.1.1. The message number shall be
replaced with the dummy value (00000) and the message sent again to the receiver. The receiver shall
not indicate that messages are missing.
Page 30, amendment to subclause A.4.2
Replace bullet item g) with the following bullet item:
g) The adjacent channel selectivity for messages shall be recorded for the upper and lower adjacent
channels as the ratio in dB of the average of the levels of the unwanted signal recorded in steps d)
and e) to the level of the wanted input signal.
