Quanum Pocket Vibration Telemetry Voltage Meter With Alarm 1) RX (Wireless Receiver Pocket Vibrator) 2) TX (LiPo Alarm Transmitter) Operating Instruction A) Binding 1) Press and hold the RX Function button 2) Switch on RX unit, the Red LED on RX will blink, 3) Press and hold the Binding button on the TX 4) Plug the balance socket of LiPo battery (2S~8S) to TX, the Red LED on TX will flash once 5) Release the Binding button, TX and RX will communicate and once the binding process successfully, the Red LED and Green LED on the RX will be ON/OFF sequentially then vibrator vibrates, at last Green LED on the RX will solid on and the Green LED on TX flash to show binding and units working properly. The TX will transmit signal to the RX. B) Normal operation 1) Switch on RX unit, the Red LED turns ON, the 3.7V LED ON shows the default alarm cell voltage is 3.7V 2) Plug the balance socket of LiPo battery (2S~8S) to TX, the Red LED will flash once and the Green LED ON. The TX will transmit signal to the RX. 3) RX received signal, the Green LED ON to show signal received correctly 4) If any one of the battery cells is lower than the preset alarm cell voltage, the vibrator will turn on and the Red LED on RX turns ON. C) Alarm Voltage Setting The default low voltage alarm for the cell voltage is 3.7V, if lower voltage is preferred, just press the Alarm Voltage Select button once, the low voltage alarm voltage will be decrease 0.1V. There are 5 LEDs to show the corresponding alarm voltages (3.7V, 3.6V, 3.5V, 3.4V, 3.3V)
