Incorrect installation can lead to serious injury and will void manufacturer’s liability and warranty. Important Safety Instructions To Be Read Prior To Operation. Essential Settings Step 1 to 3 must be completed to ensure proper operation. DD1602H 15-channel LCD emitter DD1602H Back UP Display STOP DOWN CH+CH- P2 P2 Please read following points of attention carefully before setting. Setting Notice -3- 1. Pls take the wire connnector to protect the extra free wires. 2. Operation ①The valid interval time of the buttons is within 6S, if there is no operation within 6S, the emitter will exit the present setting. ②The motor will jog or beep for hint, please do the next step after the hint. 3. Set limit position: ①After the upper/lower limit setting, and the upper/lower limit position can’t at the same position. ②After limit setting, with power off and memory function. ③Limit delete will clear all limit memory. ④It will exit limit setting when program there is no operation for 2 minutes. 4. If the emitter lost, please setting up again with new emitter. 5. One motor can store maximum 10 channels; after fully stored, if pair new channels, only the last one will be covered circularly. 2 Switch Rotating Direction (Optional) + UP DOWN Press UP and motor runs downwards, try below to switch direction. * The motor needs to be in the reversing operation without limit. * If the code is not aligned, motor jog once and long beep once, jog once for the code; If no limits, this operation will be pairing; if with limits, this operation will be pairing additional emitter. Press and hold UP and DOWN buttons simultaneously for 2S, motor jog once, the direction has been switched successfully. 1 Pairing Power on motor (1 jog and long beep once), within 7S, press STOP for 2S ( 2 jogs and 3 beeps), the motor has been paired successfully.
