Binding Method
Traditional Method: 1. Power on the receiver, its LED will turn on. Then power
off the receiver.
2. Repeat Step one twice. 3. Power on the receiver for the third time, its LED will double blink. This indicates that the receiver is in bind mode. 4. Select [BIND] on the radio, then confirm.
Binding phrase: 1. Open the ExpressLRS LUA and navigate to the Wifi Connectivity page. Select the Enable Wifi option and connect to your radio’s Wifi with a mobile phone, tablet or PC (See TX Wifi notes below). Open the WebUI (ExpressLRS web page on http://10.0.0.1/) and input a unique bind phrase of yours. (Note: Bind phrases are not secret and can be read). Save and Reboot. 2. Power up the receiver and wait 60 seconds for the LED to blink rapidly to indicate Wifi mode. Connect your phone, tablet or PC to the receiver’s Wifi (See TX Wifi notes below). Open the WebUI (ExpressLRS web page on http://10.0.0.1/) and enter the matching bind phrase previously entered on your radio. (Note: Bind phrases are not secret and can be read). Save and Reboot. Once a radio and a receiver have the same bind phrase set, they will automatically bind.

Other Important Notices
1. The maximum input voltage for the EXT-BAT (external voltage input)
telemetry reading is 35V. Do not exceed 35V or the receiver will be damaged.
2. The EXT-BAT (external voltage input) of the ER8 is accessed via the EXT-BAT
2pin JST-GH connector. The red wire must be soldered to the positive of the
battery or ESC. If no EXT-BAT power source is found, the HR8E will default to
reading the voltage on the receiver pins, only one voltage input can be used
at the any given time. 3. Please ensure that the power supply current of the
ESC BEC matches the power consumption requirements of the servo used. If using
high-voltage and high-torque servos, it is recommended to use a 2S 7.4V
battery for direct power supply or a suitable high-current UBEC. 4.
Calibration of the telemetry voltage will be required on your radio. Navigate
to the telemetry page on your radio and locate the RxBt sensor. Edit the
sensor settings and adjust the offset until the displayed reading matches the
actual voltage of the battery in the model. If there is a large difference,
adjustment of the ratio may also be required. *For best results, calibrate the
voltage of your radio using a fully charged battery of the correct cell count
intended for use in the model. 5. ExpressLRS Arming requirements and the use
of Channel 5: CH5 is required by ExpressLRS to set the Arm state of the RF
module in your radio. It is recommended to assign CH5 to a switch such as your
throttle cut switch as this will provide benefits such as dynamic power. Using
the ExpressLRS LUA or the Wifi WebUI, you can assign different channels to the
CH5 output of your receiver. Please visit https://www.expresslrs.org/ to learn
more on the importance of setting up arming.

determined by turning the equipment off and on, the user is encouraged to try
to correct the interference by one or more of the following measures: —
Reorient or relocate the receiving antenna. — Increase the separation between
the equipment and receiver. — Connect the equipment into an outlet on a
circuit different from that to which the receiver is connected. — Consult the
dealer or an experienced radio/TV technician for help.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions:(1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
