Attention, the HobbyKing®* Discovery Buzzer only works to max 5.8 volts !!
Wird er mit einer hö*heren Spannung betrieben, gibt er bei aktivierten Kanal kein Signal.
If it is operated at a higher voltage , it outputs no signal when enabled channel .
This thing is useless if you lose a model because of radio signal failure, you won't be able to trigger it with your transmitter. Recently lost a 250 mini quad in some forest because the radio gear failed and would not activate the buzzer. Certainly not a fail-safe way of finding a lost aircraft.
Bought a couple of these and connected one to the Aux channel of my Sanwa RX451 receiver.
It beeps when I first turn the receiver swithch on but doesn't do anything when I toggle the Aux switch on my Sanwa Gemini transmitter until I "flick" the steering control lever whilst the Aux switch is in the low position.
It has to be a quick sharp flick, moving the steering more slowly doesn't seem to work. Any idea why it's behaving in this way? I was hoping it would respond just when I moved the toggle switch. I've checked and the Aux channel on my transmitter is in ON-OFF mode, not mixing or anything strange.
(I've also tried one of the other four that I bought in case the first one was faulty.)
Hope you can help.
Try adjusting your end points on your Aux channel in your TX if you have them then it should work as advertised,i'm not being funny when i say if your TX has end points i only said that as i don't know of your TX,so i don't know if it's a computerized TX or not sorry.
Thanks Tank1, I've since figured it out.
It needs a slightly lower input voltage than the standard 6 volts regulated by the ESC going into the receiver. By putting a diode (1N4148 in my case) in the positive lead (red) of the buzzer it drops about 0.6v bringing the supply down to 5.4V and it then works fine on the Aux channel.
