Feidhm 1: Trasnaíocht taifeadta téipe
(The recording equipment jammer does not make any sound when it is working) It can interfere with the recording of all tape recorders. During the test, the RN-502A tape interview machine of Japan's Panasonic was used. The best interference distance is 6 meters in radius. to 90 percent . The effect of 10 places can reach 85 percent , and it can reach 75 percent at 12 meters. All that is recorded is noise.
Feidhm 2: Cur isteach taifeadta digiteach
The test uses South Korea's R200 digital voice recorder. The best interference distance is 1.5 meters, and the recording is full of noise. At 2.5 meters, the effect drops to 75 percent . Occasionally, I hear voices, but I can't understand them. At a distance of 3 meters, the effect drops to 30 percent . The recorded sound will have noise, but it can be understood. After installing the directional interview microphone, the test effect is better. The sound recorded at a distance of 4 meters is all noise, and the intermittent speech can be heard at a distance of 6 meters, and the effect reaches about 60 percent .
Feidhm 3: Cur isteach Cluaise Gan Sreang/Sreang
Tá minicíocht 118MHZ agus achar tarchurtha de 100 méadar ag an bhfeiste cluasaithe gan sreang micreafón capacitive a úsáidtear sa tástáil. Is torann iomlán é an fhuaim a chloistear, ní féidir an guth cainte a chloisteáil. Tá sé léirithe ag tástálacha, chomh fada agus is piocadh capacitive é, go bhféadfadh sé cur isteach ar an bhfuaim. Dá bhrí sin, tá sé cruthaithe gur féidir le fabhtanna sreangaithe agus gan sreang araon cur isteach agus cosc a chur ar an gcluasaire an fhuaim a chloisteáil.
Feidhm 4: Taifeadadh cur isteach ar threalamh ceamara gan sreang
Úsáideann an tástáil ceamara bioráin gan sreang 1.2G 10MW. Faoi ghníomhaíocht an jammer, ní athraíonn an íomhá, agus déantar an fhuaim torann. Is é 4 mhéadar an t-achar trasnaíochta is fearr.
Feidhm 5: Cur isteach micreafón agallaimh
Úsáideann an tástáil micreafón sárthreorach atá tiomnaithe don stáisiún teilifíse. Is é 5 mhéadar an t-achar trasnaíochta is fearr. Tá an éifeacht níos measa ag 8 méadar, agus beidh an fhuaim le cloisteáil ag 10 méadar.
Feidhm 6: Rialú cianda oscailte
Is féidir leis an achar rialaithe iargúlta 15 méadar a bhaint amach. Is í an eochair chiorcail ná an táscaire dearg a chur ar siúl, agus is é an eochair ubhchruthach an táscaire glas a mhúchadh. Is é thart ar 3 soicind am freagartha an mheaisín nuair a bhíonn sé casta air agus as.
Feidhm seacht: clog leictreonach
Tá feidhm aige mar chlog leictreonach, a thaispeánann uaireanta agus nóiméid, mar shampla: 12:18=12:18.
