warning

If the traffic signal is doing something unexpected, stop sending commands and follow your agency's procedures first. Troubleshoot the equipment after the intersection is safe.

Quick Checks

Most field issues come down to one of these:

• Is the receiver powered on, with battery to spare?
• Is the cabinet actually switched to manual?
• Is the signal cable fully seated at both ends?
• Does the battery gauge in the status bar have charge to spare (not red)?

Receiver Won't Power On

The battery is probably empty. Plug in any USB-C power source — the included Anker battery pack, a phone charger, a car charger — let it charge for a few minutes, then switch it on. If the screen stays dark even on power, contact support.

Signal Doesn't Advance

First, confirm the command is actually going out: when an advance fires, the receiver clicks audibly and the traffic-light icon appears in the status bar. (Remote and app advances also pulse the blue light twice.)

If the command fires but the lights don't change:

1. Double-check the cabinet is in Manual / Hand Control.
2. Re-seat the signal cable at the receiver and at the cabinet port.
3. Remember the controller may just be finishing a pedestrian countdown or clearance interval — give it a moment. See How Signal Timing Works.

If the command doesn't fire at all:

1. Wait a moment and try again. After each advance the receiver ignores new ones until its cooldown ends — 2 seconds by default, longer if someone changed Settings > Advanced Settings > Advance Cooldown.
2. Check the battery. If the gauge reads 0%, plug in USB-C.
3. Try the Manual Control screen instead of the remote.
4. Still nothing? Contact support.

Remote Doesn't Work

1. Press the button — does the LED ring light up at all? If not, the AA batteries are dead. Replace the set.
2. If the ring strobes rapidly (command failed), wait a moment — you may have pressed during the receiver's cooldown — then move closer and try again.
3. Check the remote is actually paired: Settings > Paired RF Remotes. Its card flashes when you press the button — if it's not listed, pair it.
4. All four remote slots full? Delete an unused remote, then pair this one.
5. Listed, fresh batteries, right next to the receiver, and it still fails every time? The remote has fallen out of sync. Delete its card and pair it again — see Range and Reliability.

Bluetooth Won't Connect

1. On the Bluetooth screen, make sure the toggle is on.
2. Tap Pair a Device and retry from the app while the window is open.
3. Still stuck, or the receiver says its device list is full (it remembers up to 12 phones)? Settings > Clear Bluetooth Devices, then forget the old pairing on the phone too, and pair fresh. (The receiver will show up under a new name.)

The app has its own troubleshooting page for phone-side issues: App Troubleshooting.

Locked Out of the Touchscreen

Tap Unlock and enter the 4-digit PIN. Forgot it? Contact us for help. See PIN Lock.

Screen Is Dark

The display sleeps to save power; the receiver is still running. Tap once to wake the screen, then tap again to press controls. You can change the sleep timing in Settings > Screen Off After — though the Manual Control screen always sleeps after 2 minutes idle, even when that's set to Always On.

"There was a problem." Screen

This screen appears if the receiver hits an internal fault it can't recover from on its own.

Keep the device powered, note the message shown, and try a power cycle. If the screen comes back, contact support with the message you recorded.

Fault Code on the Home Screen

If the home screen shows a panel reading Fault code: 0x—, one of the receiver's internal subsystems didn't start. The receiver keeps running — the code just tells you which feature is affected:

Code	What's unavailable
0x01	Battery monitoring
0x02	Bluetooth
0x04	RF remotes
0x03	Battery monitoring + Bluetooth
0x05	Battery monitoring + RF remotes
0x06	Bluetooth + RF remotes
0x07	All three

Battery monitoring (0x01) — almost always seen after powering on with a completely drained battery: the battery gauge can't start until the battery has recovered a little charge. Leave the receiver on the charger for a few minutes, then power-cycle it, and the fault clears. While this fault is showing, the battery percentage is hidden, but signal control works normally.

Bluetooth (0x02) — the phone app can't connect, but signal control and RF remotes are unaffected. Power-cycle the receiver.

RF remotes (0x04) — handheld remotes won't be received, but the touchscreen's Manual Control still works. Power-cycle the receiver.

If a code comes back after a power cycle (for 0x01: on a charged battery), contact support and mention the code you're seeing.

Firmware Update Won't Complete

Keep the device powered, give it a minute to recover, and retry from the app. A failed update doesn't harm the receiver — it keeps running its existing firmware. If updates repeatedly fail, contact support.

If the app says Service Update Required, the receiver's control board is on older firmware that can't update from the app. Contact support to schedule a one-time service update — see Service Update Required.
