ROTARY ENCODER
U se the squelch function to optimize r ec eption. When
the squelch lev el is high, only stronger sig nals will pass
thr ough the squelch ga t e , and weaker sig nals may not
be r ec eived . W hen the squelch lev el is low , the squelch
ga t e will be open even when no signal is pr esen t , causing
the scanner to scan slo wly or to stop on Objects even when
no tr ansmission is pr esen t , playing noise only . T he scanner
works best when the squelch ga t e is set so that it is closed
when no tr ansmissions are pr esen t , but able to open when
a desir ed tr ansmission oc curs . The ideal setting f or the
squelch lev el is between 9 and 11.
I f y ou find that the scanner seems to be scanning very
slo wly or st opping on frequencies with noise only , incr ease
the squelch lev el until nor mal scanning r esumes .
I n menus , the rotar y encoder scr olls up and down thr ough
the menu it ems and a single pr ess selec ts the indicated
menu option. W hen en t er ing alphanumeric da ta such as
Scan List names the rotar y encoder scr olls up and down
the char ac t er list (lett ers , numbers , punc tua tion); a single
pr ess selec ts the indica t ed char ac t er .
The rotar y encoder can be used to adjust the backlight
lev el . Press POWER briefly with backlight illumina t ed , then
rotate the encoder to incr ease or decr ease brigh tness .
