Connect to another slave via P3. Sweep freq. tuning Put EAS detector above transmitter, press “power” to detect: Fc: read 7.6~8.2MHz (VR15 for tuning)； Fs: should read 180Hz when JP7 is connected; Δ：should read 1000±50KHz (VR14 for tuning).
(factory setting) ON SW1-6 OFF Note: once changes are made to either Tx Board or Rx Board, must press “RESET1” button on the Rx Board so that the systems will reboot itself. Noise signal tuning The light DS1, DS2 and DS3 indicate the conditions of the operation: i. If they do not lit up, this means perfect condition (no noise). ii. If only DS1 lit up, the condition is good. iii. If both DS1 and DS2 lit up, the condition is fair and the system can still operate effectively. iv.

If there were high interference, the system will shut itself off to avoid false alarm. To ensure the system will operate well, must try and eliminate obvious cause of interference. Then, follow the below instructions:1. In Tx, adjust VR14 until Sw reads 700 ~ 750. 2. In Rx, change jumper in JP1, moving one slot to the right i.e. from position 1/2 to 2/3. This is the case when there is high noise interference and detection distance is more than 1.5m. 3. In Rx, change jumper in JP2, moving one slot left i.e.
