◆◆ 2.1.2. ７e“ommen”ation of use of earphone
We re“ommen” using earphone while “he“king to re”u“e bur”en of “he“king. If you hear low soun” from earphone,
see s“reen.
２０-】20 automati“ally turns off after 5 minutes of no operation.
◆ 2.2 （he“king operation by button
◆◆ 2.2.1. ８ensing
５ush re” button.
２０-】20 “ontinues “he“king while you keep pushing re” button.
After you release re” button, ２０-】20 in”i“ates ”ata you “he“ke” last.
２０-】20 start sensing again by se“on” push of re” button.
２０-】20 points sensing area by laser.
When you release re” button,
laser pointer stops.
◆◆ 2.2.2. ７ange swit“hing
You “an swit“h range by pushing white button at sensing (=while you are pushing re” button ).
７ange swit“hing “annot be ”one while ２０-】20 is not sensing.
７ange swit“hing or”er is as follows.
AU９４→１(low)→２(mi””le)→H(high)→AU９４
At AU９４ range setting, ２０-】20 swit“hes range from １. An” if sense” value is high, automati“ally swit“h range
to ２, an” to １.
At the “ase that you start “he“king again after you stoppe”, ２０-】20 (at AU９４ range setting) start sensing
at １ range.
７ange setting (AU９４，１，２，H) is kept after turning off.
２０-】20 starts sensing at range memorize” at previous sensing.
固 In the “ase ２０-】20 ”isplays ４VE７ at fixe” range setting su“h as １, ２, an” H, it means s“ale-over.
８wit“h to higher range.
