VEZETÉK NÉLKÜLI 

AJTÓCSENGŐ

UT-WD136

1. Az ebben a csomagban szállított adóegység(ek) párosítva vannak vevőegység(ek)kel, és be vannak  
  állítva a “Dingdong” alapértelmezett dallamra, AMENNYIBEN EZ NEM ÍGY VAN, kérjük, hogy tanulmá- 
  nyozza a „Gyors indítás” című fejezetet és annak segítségével párosítsa az adóegység(ek)et és  
  vevőegység(ek)et, majd állítsa be kedvenc dallamát/dallamait.

2.  A fém, a falak, a mennyezet és az elektromos készülékek által kibocsátott egyéb rádiófrekvenciás jelek  
  befolyásolhatják a vezeték nélküli ajtócsengő rádió jelét. Általában a hatótáv elérheti a 180 métert 
  a nyílt, interferenciamentes térben, míg akadályokkal rendelkező környezetekben a hatótáv 18-90 m 
 lehet.

3. Nem tanácsos az adókészüléket fém felületre szerelni, mivel a fém blokkolhatja a rádiófrekvenciás 
  jeleket az adóegység és a vevőegység között. Azonban, amennyiben csak így lehet felszerelni az  
  adóegységet, akkor a csavarok helyett a készülékkel szállított kétoldalas ragasztószalag használatát  
 javasoljuk.

4.  Az adóegységben használt elem típusa: 

23A.

 Amennyiben gyenge állapotú elem van az adóegységben,  

  akkor a hatótáv csökkenni fog.

5. Nem tanácsos az adóegységet közvetlenül a külső ajtóra mindennemű védelem nélkül szerelni, mivel 
  az ily módon történő felszerelés következtében felgyorsulhat a műanyagok öregedése.

1.  Kapcsolja be az adó- és a vevőegységet.

2. Dallambeállítás és az adó-, illetve vevőegység párosítása:

(1) Nyomja meg a      vagy a     gombot és válassza ki kedvenc dallamát a beprogramozandó vevőegységen.

(2) Tartsa lenyomva a        gombot körülbelül 5 másodpercig, majd engedje fel, amikor megszólal egy
  Ding-dong dallam és a LED jelzőlámpák elkezdenek villogni.

(3) Nyomja le az adóegység gombját annak érdekében, hogy elküldjön egy jelet a vevőegységhez 
  a működés ellenőrzése céljából. Amennyiben a dallam beállítása (a párosítás) sikeres, a 
  vevőegység automatikusan le fogja játszani a kiválasztott dallamot.

3.  Hangerő szabályozás

 

Nyomja meg a        gombot a vevőkészüléken. E kapcsoló a magas és alacsony hangerők között vált.

Köszönjük, hogy megvásárolta vezeték nélküli ajtócsengőnket. Ezen ajtócsengő telepítése kifejezetten 
egyszerű, esetében nem kell bajlódni a vezetékekkel. Egyszerűen csak be kell dugni a vevőegységet a 
konnektorba, az adót fel kell szerelni, és már kész is! Az ajtócsengő 52 dallammal, négy hangerő szinttel 
szólaltatható meg abból a célból, hogy megfeleljen igényeinek és 180 méter távolságig használható nyílt, 
interferenciamentes térben.

Kérjük, hogy használat és telepítés előtt körültekintően olvassa el a jelen felhasználói kézikönyvet.

1.The transmitter(s) supplied with this kit is(are) paired with 

receiver(s) and set to default tune “Dingdong”,IF NOT, please refer to 

the “

Getting Started

” to pair the transmitter(s) with receiver(s) and set 

your favorite tune(s).

2.Metal, walls, ceilings and other RF signals from electronic devices 

can affect the radio signal of the wireless doorbell. Generally the 

operating range can reach up to 600 feet in the open air and non-

interference environment, and 100~300 feet within obstructive 

environments. 

3.It is not advisable to mount the transmitter onto metal surfaces as 

the material can block RF signals between the transmitter and the 

receiver. However, if this is the only option then we recommend that 

you use the sticky pad provided as opposed to using the provided 

screws. 

4.The battery using in transmitter is 

23A

,Operating range will 

decrease if battery in transmitter is in low power status.

5.The push button is not advisable to mount the transmitter in the 

outdoor directly without any shelter which could accelerate aging of 

plastic materials.
