Quick Reference and understanding the product

- Connect the wire harness to the telemetry system with the appropriate connectors as shown on label.
- Connect the ESC in series with the V/I sensor. Do not connect battery or any power source to the unit.
- Connect the telemetry system to the receiver bind location.
- Ensure Spektrum transmitter telemetry options are selected and enabled properly along with the appropriate measurement system (Imperial / Metric) selected.
- Insert bind plug to the telemetry system.
- Execute bind procedure by connecting the battery to the V/I sensor for providing power to the unit. Both receiver and telemetry system should flash quickly.
- Upon binding, you are now ready to use the telemetry system!

Below is the V/I/mAh sensor. This sensor's XT60 connector should connect in series between the battery and ESC.

LemonRX V/I/mAh sensor

Below is the external temperature sensor. (The red wire is used for RPM sensing and it may works with some of the brushless system in the market only. Cut this wire and connect to any one of the brushless motor's wire. Please change the gear ratio in Spektrum telemetry RPM setting to around 0.2 for reasonable reading and do fine adjustment as necessary.)

Below is the wire that connects between the telemetry system and the receiver's bind port. Telemetry power is obtained via this wire from the receiver and also enable both units binding to the transmitter.
