channel spacing.
4.4 Warm up
After being switched on the equipment shall meet the requirements of the present document within one minute under

4.5 Protection of the transmitter
4.5.1 Definition
The protection of the transmitter represents the ability of the transmitter to be protected against malfunction due to
