The time necessary to change over from transmission to reception or vice versa, shall not exceed 0,3 s.
4.5 Safety precautions
Measures shall be taken to protect the equipment against the effects of overcurrent or overvoltage.
Measures shall be taken to prevent damage to the equipment if the electrical power source produces
transient voltage variations and to prevent any damage that might arise from an accidental reversal of
polarity of the electrical power source.
Means shall be provided for earthing exposed metallic parts of the equipment but this shall not cause any
terminal of the source of electrical energy to be earthed.

and shall be automatically isolated from all electrical power sources if the protective covers are removed.
Alternatively, the equipment shall be constructed in such a way as to prevent access to components
operating at such voltages unless an appropriate tool is used such as a nut-spanner or screwdriver.
Conspicuous warning labels shall be affixed both inside the equipment and on the protective covers.

Page 12

test conditions (subclauses 5.4.1 and 5.4.2 applied simultaneously).

Page 13
ETS 300 698: March 1997

During conformance testing, the equipment shall be supplied from a test power source capable of
producing normal and extreme test voltages as specified in subclauses 5.3.2 and 5.4.2.
The internal impedance of the test power source shall be low enough for its effect on the test results to be

of the equipment.
During testing, the power source voltages shall be maintained within a tolerance of ±3 % relative to the
voltage level at the beginning of each test.
5.3 Normal test conditions
5.3.1 Normal temperature and humidity
The normal temperature and humidity conditions for tests shall be a combination of temperature and
humidity within the following ranges:
- temperature: +15°C to +35°C;
- relative humidity: 20 % to 75 %.
5.3.2 Normal power sources
5.3.2.1 Mains voltage and frequency
The normal test voltage for equipment to be connected to the ac mains shall be the nominal mains
voltage. For the purpose of this ETS, the nominal voltage shall be the declared voltage or any of the
declared voltages for which the equipment is indicated as having been designed. The frequency of the test
voltage shall be 50 Hz ± 1 Hz.
5.3.2.2 Battery power source
Where the equipment is designed to operate from a battery, the normal test voltage shall be the nominal
voltage of the battery (12 V, 24 V etc.).
5.3.2.3 Other power sources
For operation from other power sources the normal test voltage shall be that declared by the
manufacturer.
5.4 Extreme test conditions
5.4.1 Extreme temperatures
For tests at extreme temperatures, measurements shall be made in accordance with subclause 5.5, at a
lower temperature of -15°C ± 3°C and an upper temperature of +55°C ± 3°C.
5.4.2 Extreme values of test power sources

Page 14
ETS 300 698: March 1997
5.4.2.3 Other power sources
For operation from other power sources the extreme test voltages shall be agreed between the testing
authority and the equipment manufacturer.
5.5 Procedure for tests at extreme temperatures
The equipment shall be placed in the test chamber at normal temperature. The maximum rate of raising
or reducing the temperature of the chamber shall be 1°C/minute. The equipment shall be switched off
during the temperature stabilizing periods.
Before conducting tests at extreme temperatures, the equipment in the test chamber shall have reached
thermal equilibrium and be subjected to the extreme temperature for a period of 10 hours to 16 hours.
For tests at the lower extreme temperature, the equipment shall then be switched on to standby or receive
condition for one minute, after which the equipment shall meet the requirements of this ETS.
For tests at the higher extreme temperature, the equipment shall then be switched on in the high power
transmit condition for half an hour, after which the equipment shall meet the requirements of this ETS.
The temperature of the chamber shall be maintained at the extreme temperatures for the whole duration
of the performance test.
At the end of the test, with the equipment still in the chamber, the chamber shall be brought to normal
temperature in not less than 1 hour. The equipment shall then be exposed to normal temperature and
relative humidity for not less than 3 hours or until moisture has dispersed, whichever is the longer, before
the next test is carried out. Alternatively, observing the same precautions, the equipment may be returned
direct to the conditions required for the start of the next test.
6 General conditions of measurement
6.1 Arrangements for test signals applied to the receiver
Test signal sources shall be connected to the receiver antenna port in such a way that the impedance
presented to the receiver antenna port is 50 Ω, irrespective of whether one or more test signals are
applied to the receiver simultaneously.
The levels of the test signals shall be expressed in terms of the electromotive force (emf) at the terminals
to be connected to the receiver.
The nominal frequency of the receiver is the carrier frequency of the selected channel.
6.2 Squelch
Unless otherwise specified, the receiver squelch facility shall be made inoperative for the duration of the
conformance tests.
6.3 Normal test modulation
For normal test modulation, the modulation frequency shall be 1 kHz and the frequency deviation shall be
3 kHz.
6.4 Artificial antenna
When tests are carried out with an artificial antenna, this shall be a non-reactive, non-radiating 50 Ω load.
Conformance tests of Radio Frequency (RF) characteristics are performed using an artificial antenna,
however the manufacturer should be aware that normally used VHF antennas when installed, although
presenting a nominal impedance of 50 Ω, may exhibit Voltage Standing Wave Ratios (VSWR) up to
2 depending on the frequency in use. Under such conditions the equipment is required to function
correctly.
Page 15
ETS 300 698: March 1997
6.5 Arrangements for test signals applied to the transmitter
For the purpose of this ETS, the audio frequency modulating signal applied to the transmitter shall be
produced by a signal generator applied to the connection terminals replacing the microphone transducer.
