Tunecast ii fm transmitter accsdigital with dc jack
We add a great convenience feature with our unique auto on/off function. It frees you from having to manually toggle your tunecast ii on/off switch by simply powering on when an audio signal is detected. If no signal is detected for a period of 60 seconds, your tunecast ii switches off. This innovation preserves battery life while making your outstanding mobile audio experience simpler to enjoy. |
