Nta:
- 8 raws tau txais cov teeb liab, txhua lub channel muaj 50 lub teeb liab raws xaiv, thiab txhua lub channel tau nce los ntawm 250KHz; Rau txhua channel yog 49.75MHz;
- Stable PLL digital theem-xauv voj synthesis thev naus laus zis thiab chip Circuit Court tau txais los ua kom muaj txiaj ntsig zoo ntawm kev ua haujlwm tag nrho;
- UHF band kis tau tus mob, ntau zaus: 500MHz-690MHz;
- Tib lub sijhawm tuaj yeem siv rau 5 teev ntawm cov tshuab tib lub sijhawm, uas yog, 5 receivers thiab 80 transmitters tuaj yeem siv tib lub sijhawm;
- LCD npo qhia ua haujlwm channel, ua haujlwm zaus taw tes, tau txais cov teeb liab thiab lub teeb liab;
- 4 roj hmab txais cov kav hlau txais xov yog teem rau sab nraum qab ntawm lub receiver los txhim kho cov cim tau txais, thiab cov tsos yog elegant thiab dlej;
- 8 cov khoom sib npaug, 1 cov khoom sib xyaw tsis sib npaug thiab 1 cov khoom sib xyaw ua ke ntawm sab nraub qaum, haum rau kev sib txuas ntau yam khoom siv sab nraud;
- Nws tsis txwv rau ib qho channel nkaus xwb uas tuaj yeem ua ke nrog ib qho kev sib kis, thiab tib txoj kev sib kis tau tuaj yeem sib cuam tshuam hauv 400 raws ntawm ob txoj kev. Interoperability thiab humanization ntawm high-tech tsim;
- Lub zog noj ntawm lub microphone yog 80 mA, siv los ntawm 1.5V roj teeb (3pcs), thiab tuaj yeem siv tsis tu ncua rau 12 teev;
- Lub microphone tau nruab nrog lub teeb xiav lub nplhaib los qhia txog kev ua haujlwm ntawm lub rooj sib tham microphone (lub teeb lub nplhaib qhia xiav thaum ua haujlwm);
- Siv nrug: Qhib ib puag ncig: 80-100m ; Ib puag ncig nyuaj: 50-80m
- Haum rau txhua yam kev sib tham thiab kev nthuav qhia.
