Device Basics
A quick tour of the receiver hardware: the status light, the USB-C port, the signal jack, the power switch, and the battery.
Status Light
The receiver has a single status light on the top of the device. Blue is the receiver talking to you; red and green appear only while charging.
| Light | Meaning |
|---|---|
| Blue, steady on | Powered on and running normally. |
| Blue, two quick pulses | An advance command just fired — from a remote or the app. |
| Blue, slow breathing | Pairing mode is open, for Bluetooth or for a remote. |
| Blue, fast flashing | Alert — the battery is empty. The receiver has stopped sending commands to protect itself — plug in USB-C power to resume control. |
| Red | Charging. |
| Green | Fully charged. |

Power LED. The receiver works exactly the same — and if the battery ever runs
empty, the fast warning flash still shows so you don't miss it.
USB-C Charging
The receiver charges through its USB-C port on the top of the device, and it isn't picky:
- Any reputable USB-C cable and any standard 5 V USB power source works — a wall adapter, a car charger, or a portable backup battery pack like the one included with your device.
- Plugging in USB-C starts charging whether the device is on or off.
- The port is for charging only; it doesn't carry data.
For long deployments, just leave a USB-C power bank plugged in. A standard phone charger or field battery pack will keep the receiver topped up indefinitely.
Signal Cable Jack
The jack on the top right is how PRIORITYwave talks to the traffic cabinet.
Use the included signal connection cable (3.5 mm TRS to 1/4" TRS cable) — smaller end into the receiver, and the larger end into the cabinet's manual push-button port. If you ever need a replacement or longer variant, any reputable cable of the same type works fine.
Power Switch
The power switch is a simple on/off switch — On powers it up; off shuts it down completely.
Battery
PRIORITYwave runs on an internal rechargeable battery.
- The charge level shows as a percentage in the top status bar, with a charging bolt while USB-C is connected.
- At 0%, the receiver keeps a small protective reserve and stops accepting advance commands until you plug in power. The status light fast-flashes blue so you know why.
Top up over USB-C before heading out, and keep a battery pack in the kit for long shifts.
