Introduction
The telephone network repeater or The call signal peripheral circuit to the loud than the original. It’s a circuit that we design follow the request. One of my friends. His ears are a bit tight as such phone rings only. He does not quite go ahead.
Therefore, it is my responsibility, To help design. For the amplify the signal from phone loud sound more than ever. I used to attach circuits with a buzzer or a electric bell, to act as the increase loud sound of bell telephone. For some of you who want to use this a circuit. If it is modified by change light bulb replace the electric bells as well. When the call came in, the lamp will be flashing by the call signal.

- Plug power adaptor into AC power socket and finish installation.
Technique Supporting
- If still no signal receipt after activated repeater, please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70DBM.
- If can not call out, please adjust the direction of outdoor antenna.
- If strength is not steady, please check if outdoor & indoor antennas are too close. Please ensure the outdoor and indoor antenna have distance of 20
Accessories
SelectionOutdoor antenna use 7 unit yagi type antenna, indoor antenna use board or rooftop antenna and signal wire use coaxial-cable.
