Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam wholesale, qhib tus nqi thiab kev paub pub dawb ib zaug dhau los ua txoj kev yuav khoom uas tib neeg nyiam.Txawm li cas los xij, thaum cov tub lag luam muab cov neeg siv khoom nrog cov khoom siv yooj yim no, kev nyab xeeb ntawm cov khoom kuj yog ib qho teeb meem tseem ceeb uas cuam tshuam cov tub lag luam.Vim yog qhov chaw ua tiav thiab qhib kev yuav khoom, qhov kev poob ntawm cov khoom yog qhov kev zam.Tshwj xeeb, qee cov khoom me me thiab ua kom zoo zoo feem ntau tsis muaj nqi tsawg.

Tau ntsib nrog qhov teeb meem pos, peb yuav tsum ua tib zoo saib xyuas nws thiab kho nws kom raug.Yog tias nws tsis ua haujlwm, nws yuav cuam tshuam ncaj qha rau kev ciaj sia ntawm lub khw.Nws puas xav tias exaggerated me ntsis?Qhov tseeb, nws tsis yog exaggerated.Rau ib yam khoom, koj yuav tsum tau muag peb lossis ntau dua los ua kom poob.

Txhawm rau daws qhov teeb meem no, thawj qhov uas cov tub lag luam feem ntau xav txog yog kev teeb tsa kev saib xyuas, tab sis kev saib xyuas tsuas yog ib qho cuab yeej los nrhiav cov teeb meem tom qab, thiab tsis tuaj yeem ua tiav raws sijhawm.Vim tias tom qab tag nrho, tsis muaj ntau tus neeg ua haujlwm thiab lub zog los saib xyuas qhov kev tshuaj ntsuam xyuas kom pom cov neeg siv khoom twg muaj teeb meem.Nws tsuas tuaj yeem tshawb nrhiav tom qab ntawd, tab sis cov khoom tau poob rau lub sijhawm no.

Qhov kev daws teeb meem tam sim no yog txhawm rau txhim kho EAS cov khoom siv hluav taws xob tshawb pom.Cov khoom no yog lub sij hawm-sensitive.Yog tias ib qho khoom lag luam tsis muaj kev cuam tshuam dhau los ntawm qhov chaw kuaj pom qhov rooj, nws tuaj yeem ceeb toom rau lub sijhawm kom ceeb toom tus neeg muag khoom hauv khw.

Tam sim no, feem ntau yog ob hom ntawm lub khw muag khoom loj los tiv thaiv tub sab qhov rooj uas tau siv dav hauv khw.Ib qho yog 8.2Mhz (feem ntau hu ua RF SYSTEM), thiab lwm qhov yog 58khz (AM SYSTEM).Yog li qhov zaus twg zoo dua?Yuav xaiv li cas?

1. Nyob rau theem kev, feem ntau RF rooj vag tam sim no siv imitating signals, thaum lub rooj vag AM siv digital kis tau tus mob.Yog li ntawd, AM cov rooj vag yog qhov tseeb dua hauv kev paub txog cov teeb liab, thiab cov khoom siv tsis raug cuam tshuam los ntawm lwm cov cim tsis cuam tshuam.Cov cuab yeej ruaj ntseg zoo dua.

2. Txheeb xyuas cov channel dav, qhov kev saib xyuas zoo tam sim no ntawm RF qhov rooj yog cov ntawv muag muag 90cm-120cm tawv daim ntawv lo 120-200cm, AM qhov rooj tshawb pom lub sijhawm muag daim ntawv lo 110-180cm, daim ntawv nyuaj 140-280cm, kuj hais lus, AM Kev kuaj pom qhov rooj Qhov ncua sij hawm yuav tsum dav dua, thiab cov khoom siv hauv khw yuav pom qhov dav dua.

3. Hom kev pab tu.Vim yog lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm RF system, RF cim npe tau yooj yim cuam tshuam thiab tiv thaiv los ntawm tib neeg lub cev, tin foil, hlau thiab lwm yam cim, ua rau tsis ua haujlwm ntawm kev saib xyuas ntawm cov khoom ntawm cov khoom siv no.Hais txog kev hais lus, cov cuab yeej siv tau zoo dua, txawm tias ntawm cov khoom ua los ntawm tin foil thiab lwm yam ntaub ntawv, nws tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv tub sab.

4. Nyob rau hauv cov nqe lus ntawm tus nqi, vim hais tias ua ntej daim ntawv thov ntawm cov khoom siv RF, tus nqi qis dua li cov khoom siv AM.Txawm li cas los xij, nrog kev txhim kho txuas ntxiv thiab kev loj hlob sai ntawm AM cov cuab yeej hauv xyoo tas los no, tus nqi tau maj mam txo qis, thiab tam sim no tus nqi sib txawv ntawm ob qho khoom siv tau maj mam txo.

5.Tshem tawm cov nyhuv thiab cov khoom siv.Vim qee qhov teeb meem ntawm cov khoom siv RF, muaj tsawg dua thiab tsawg dua cov tuam txhab lag luam nqis peev hauv RF cov cuab yeej tshawb fawb thiab kev tsim kho.Cov khoom siv RF muaj chav tsawg dua rau kev txhim kho dua li AM cov khoom siv hauv cov khoom lag luam tshiab lossis kev tshawb fawb thiab kev tsim kho.
