🇨🇦 CANADA — DJI O4 Relay User Guide Hub: Setup, Linking, Range, LEDs, Firmware & Battery Care for Canadian Operators

This Canadian edition is written for Canadian DJI Agras operators in the orchards and vineyards of the Okanagan, Niagara and Quebec’s fruit belt. It is the hub for the whole O4 Relay manual: setup, linking and activation, field placement, LEDs, firmware, charging, storage and specifications. The procedure, specifications and warnings below are identical to the original edition linked above — the hardware does not change at the border. What changes for a Canadian operator is the regulatory and purchasing context: the aircraft this DJI O4 Relay supports falls into Transport Canada’s medium RPAS class (25–150 kg) and flies on an Advanced Operations pilot certificate under the November 2025 rules, with a Special Flight Operations Certificate for anything outside that envelope, and pricing is shown in Canadian dollars. Ares Acres stocks the O4 Relay signal repeater system and antennas referenced in this guide as genuine DJI Agras OEM parts, ships them to Canada with free standard shipping, and shows CAD pricing at checkout.

This visual manual reorganizes DJI O4 Relay User Guide v1.0 into focused operating, diagnostic and maintenance tutorials. The original source is compact, so the cluster is intentionally task-based rather than stretching the same information across broad SEO chapters.

Quick Answer: Charge the relay, install its antennas, power it on and mount it above the crop canopy. Link the relay to the remote controller through DJI Agras and let the aircraft link automatically. Keep the antennas unobstructed, use the LED guide to separate battery state from linking state, and maintain the internal battery with DJI's specified charging and storage ranges.

DJI O4 Relay charging antenna installation power and mount visual — The original manufacturer illustration provides the visual backbone for the manual cluster.

DJI O4 Relay visual manual index

DJI O4 Relay linking and activation visual — Link the remote controller first; the aircraft then links automatically.

DJI O4 Relay field setup guidance — The source recommends relay height at least 2 m above the crop canopy and unobstructed antennas.

DJI O4 Relay LED status quick reference — Battery and linking states are separated into different LED references.

Existing relay tutorial

The store already has a broader DJI Agras T100 Tutorial: How to Use the DJI Agras Relay. This manual cluster does not replace it; instead, the new pages provide source-specific visual references for setup, linking, battery management, firmware and specifications.

Exact hardware paths

The complete relay is the DJI Agras T100 OEM O4 Relay Signal Repeater System (USA Version). A verified exact replacement O4 Relay Antenna Pair is also available. Linking and activation in the T100 workflow use the DJI Agras T100 OEM Remote Controller.

Canadian Operator FAQ: O4 Relay User Guide

Does Ares Acres ship the O4 Relay signal repeater system and antennas to Canada?

Yes. Ares Acres ships genuine DJI Agras OEM parts, including the O4 Relay signal repeater system and antennas referenced in this guide, to Canada with free standard shipping, and Canadian customers see CAD pricing at checkout.

Do I need an SFOC to use the DJI O4 Relay with my DJI Agras in Canada?

The DJI O4 Relay itself needs no aviation authorization. The DJI Agras aircraft it supports falls into Transport Canada’s medium RPAS class (25–150 kg) under the November 2025 rules and is flown within visual line of sight on an Advanced Operations pilot certificate; a Special Flight Operations Certificate is still required for operations outside that envelope, such as beyond visual line of sight or payloads Transport Canada treats as dangerous goods. Confirm current requirements with Transport Canada and your provincial regulator before operating.

Is this O4 Relay manual different for Canadian operators?

No. The O4 Relay manual described here is identical in every country; only the regulatory framework, the purchasing path and the units used in this guide differ. Confirm current requirements with Transport Canada and your provincial regulator before operating.
