Njira yosinthira: Kusintha pafupipafupi kwa Channel Channel: ma infrared automatic frequency modulation 200

Kutentha kwa ntchito: kuchotsera 18 digiri Celsius mpaka 50 digiri Celsius

Njira ya Squelch: kuzindikira kwaphokoso kokha ndi ma ID code squelch

Kutalika: 45KHz

Mtundu wamphamvu:> 110dB

Kuyankha kwamawu: 60Hz-18KHz

Chiyerekezo chambiri-ku-phokoso:> 105dB

Kusokoneza kwathunthu: <0.5%

Zizindikiro zolandila:

Njira yolandirira: kutembenuka kwapawiri kwa superheterodyne, kuwongolera kawiri kulandila kowona kosiyanasiyana

Oscillation mode: PLL gawo lotsekedwa loop

Mafupipafupi apakatikati: ma frequency oyamba apakati: 110MHz,

Wachiwiri wapakatikati pafupipafupi: 10.7MHz

Mawonekedwe a Antenna: Mpando wa TNC

Kuwonetsa mawonekedwe: LCD

Kumverera: -100dBm (40dB S/N)

Kuponderezedwa kwabodza:> 80dB

Kutulutsa mawu:

Zopanda malire: +4dB(1.25V)/5KΩ

Kuchuluka: +10dB(1.5V)/600Ω

Zizindikiro za Transmitter: (908 kukhazikitsa)

Oscillation mode: PLL gawo lotsekedwa loop

Mphamvu zotulutsa: 3dBm-10dBm (kutembenuka kwa LO/HI)

Mabatire: 2x “1.5V No. 5” mabatire

Panopa: <100mA(HF), <80mA(LF)

Gwiritsani ntchito nthawi (batire ya alkaline): pafupifupi maola 8 pamphamvu kwambiri

Kulephera kosavutachithandizo

zizindikiro zosagwira ntchito	Wonongekachifukwa
Palibe chowonetsa pa wolandila ndi transmitter	Palibe mphamvu pa transmitter, mphamvu yolandila siyolumikizidwa bwino
Wolandila alibe chizindikiro cha RF	Magulu afupipafupi olandila ndi ma transmitter ndi osiyana kapena kunja kwa mulingo wovomerezeka
Pali ma radio frequency signal, koma palibe ma audio	Maikolofoni ya transmitter sinalumikizidwe kapena kutsitsa kolandila nakonsochakuya
	Kusokonekera kwaupangiri wamawu
	Kukhazikitsa mode chete
Phokoso lakumbuyo la siginecha yamawu ndi yayikulu kwambiri	Kupatuka kwa ma frequency modulation ndikochepa kwambiri, kulandira linanena bungwe magetsi Mlingo ndi otsika, Kapena pali chizindikiro chosokoneza
Kusokoneza kwa ma audio	Kutumizaterkusinthasintha kwafupipafupi kumasiyanansolalikulu, wolandila linanena bungwe magetsi mlingo ndi waukulu kwambiri
Mtunda wogwiritsa ntchito ndi waufupi, chizindikirocho sichikhazikika	Mphamvu yokhazikitsira ma transmitter ndiyotsika, ndipo squelch yolandila ndiyozama kwambiri. Kuyika kolakwika kwa mlongoti wolandila ndi kusokoneza kwamphamvu kwa batri mozungulira.
