The remote control signals the low battery level. The battery’s life: about 20 000 typical transmissions (transmission length: 0,5s). The remote control cooperates with any type of receiver produced by GORKE. We advise to configure sets using the superheterodyne receivers. The range of such sets reaches up to 1000 metres. The configuration of RNB 101S with the superreactive receiver (RSU) results in 50% shorter range (because of the lower sensitivity of the receiver). The set consists of the remote control, antenna and a case with a belt hook. If there is a need, we can prepare a version with 2, 3, 4, 5, 6, 7 or 8 buttons.
