1. Introduction
The Buff HUB Remote for Canon is a wireless trigger designed to mount onto your camera's hot shoe, enabling wireless firing of flash units. It sends a firing signal to all compatible flash units equipped with CyberSync receivers or transceivers. Simply match the frequencies across all components for seamless operation.
This remote is unique in the Buff line for providing High-Speed Sync (HSS) and Through-The-Lens (TTL) capabilities when used with the LINK800WS flash unit. It also facilitates connection between your flash units and the Paul C. Buff, Inc. App, offering enhanced control from your smartphone.
Key features include a wireless working range of up to 350 feet via radio frequency (2.4 GHz band), a locking wheel hot shoe contact, the ability to wirelessly fire an indefinite number of lights, 16 selectable frequencies, and a rechargeable lithium-ion battery with reduced power draw during sleep mode for extended life. It is compatible with all CyberSync Receivers and Transceivers (CSR, CSRB, CSR+, CSRB+, and CSXCV).

Note: While this video features a Canon BR-E1, the operational principles for a Bluetooth remote with Canon cameras are similar to the Buff HUB Remote.
3. Setup
3.1 Battery Installation
The Buff HUB Remote uses a CR2032 coin cell battery. To install or replace the battery, locate the battery compartment on the remote, typically secured by a small screw. Use a precision screwdriver to open the compartment, insert the new battery with the positive (+) side facing up, and then securely close the compartment.

- Navigate to the camera's menu system.
- Locate the Wi-Fi/Bluetooth connection settings.
- Ensure Bluetooth settings are enabled.
- In the camera's shooting menu (often indicated by a camera icon), find the Remote control option.
- Change the Remote control setting from 'Disable' to 'Enable'.

4. Operating the Buff HUB Remote
4.1 Basic Operation
Once paired, the remote can control your camera's basic functions:
- Taking Photos: With the mode switch set to still photo mode, press the shutter button on the remote. The camera will autofocus (if enabled) and then capture a photo.
