1.3 Multifunction equipment which is subjected simultaneously to different clauses of this
standard and/or other standards shall meet the provisions of each clause/standard with the
relevant functions in operation; details are given in 7.2.1.
1.4 The limits in this standard have been determined on a probabilistic basis, to keep the
suppression of disturbances economically feasible while still achieving an adequate radio
protection. In exceptional cases radio frequency interference may occur, in spite of
compliance with the limits. In such a case, additional provisions may be required.

click
a disturbance, the amplitude of which exceeds the quasi-peak limit of continuous disturbance,the duration of which is not longer than 200 ms and which is separated from a subsequent disturbance by at least 200 ms. The durations are determined from the signal which exceeds the i.f. reference level of the measuring receiver A click may contain a number of impulses; in which case the relevant time is that from the beginning of the first to the end of the last impulse.
NOTE Under certain conditions, some kinds of disturbances are exempted from this definition (see 4.2.3)
喀呖声-click
一种骚扰,幅度超过连续骚扰准峰值的限值,持续时间不大于200ms,而且后一个骚扰离前一个骚扰至少200ms。持续时间由超过测量接收机中频参考电平的信号确定。
一个喀呖声可能包含许多脉冲;在这种情况下,相关时间是从第一个脉冲开始到最后一个脉冲结束的时间。
注:在一定条件下,某些类型的骚扰不包括在此定义内(见4.2.3)。
