of very high peak energy; typical and most well known is the car ignition

static noise peaks, so that that the desired signal is not affected.

(emergency channel). 9 will blink on the display and it will not be possible to
accidentally change the channel.

control enables the LCR function (Last Channel Recall).

to activate the EN (English) or EC (European) bands.

ton the two filters ANL/NB will be activated; while if you keep it pressed,

clockwise till the background noise disappears or rotate it counter-clockwise
(DS position) and stop after you hear a "clic". Hold down the FILTER/SCAN
button. The radio will automatically and repeatedly scan all channels and will
stop on a busy channel.
