1. Introduction
The AODELAN E3+ is a versatile 2.4GHz wireless flash trigger system designed for Canon EOS cameras and Speedlites. It functions as both a transmitter (Tx) and a receiver (Rx), offering E-TTL II/E-TTL autoflash capabilities, manual flash, stroboscopic flash, and High-Speed Sync (HSS) up to 1/8000s. The E3+ transmitter includes a built-in AF assist light for improved autofocus performance in low-light conditions, a feature not found in the Canon ST-E3-RT.
This system allows for precise control over multiple flash units, supporting up to 5 groups and 15 individual Speedlites, with a transmission distance exceeding 100 meters (328 feet).

5. Setup Guide
5.1. Battery Installation
Both the E3+ Transmitter (Tx) and Receiver (Rx) require 2 x AA alkaline batteries or AA NI-MH rechargeable batteries. Ensure correct polarity when inserting batteries.
5.2. Mounting the Transmitter (Tx)
Attach the E3+ Transmitter securely to your camera's hot shoe. The integrated hot shoe mounting seal ring provides dust and dirt resistance, ensuring a reliable connection between the camera and the transmitter.
5.3. Mounting the Receiver (Rx)
If you are using an older Canon TTL flash without a built-in radio system, or another brand's flash, attach it to the E3+ Receiver's hot shoe. This allows the flash to be controlled wirelessly by the E3+ Transmitter or a compatible Canon RT Speedlite.
