BTT-900 Curl Cord Transmitter
BTT-900 is long term curl cord transmitter. Transmitter box is separated to maintain the flexibility of curl cord and prolong battery life. BTT-900 is used in combination with UCR-120GX for automatic recording.


1. Long battery life. Comparing to BTT-720, BTT-900 has ten times longer battery life.

2. Easy installation. Curl cord is set like BTT-720 and place transmitter box behind desk.
