Testing & Diagnostics Guide
Find your symptom below and work through the steps in order. Each section lists the most likely causes first, the fix for each, and what to send us if it is still not resolved. Last reviewed: September 9, 2026.
Test the system on a table before you mount anything. Most faults reported after installation are cable or setup issues that a bench test catches in minutes, and it is far easier to fix them indoors.
- Connect the base station, speaker post (or substation) and power supply exactly as the quick guide shows, using the supplied cable.
- Power on. Confirm the base station boots and, on Kit 3, the 5-inch touch screen responds.
- Pair every wireless headset (Kit 2 and Kit 3) and confirm each shows as paired. On Kit 3 note which headset is labeled Main and which is Listening.
- Have one person speak at the speaker post while another listens at the base station or headset: confirm audio both ways (inbound and outbound).
- On Kit 3, wave a hand or move a metal object in front of the ProPanel® sensor: the mic and speaker should go live, then mute again about three minutes later.
- If anything fails on the bench, work through the matching symptom below before installing.
Keep the box and packing until the system passes on the bench and again after installation.
Applies to: Pro Intercom System AIO-K3-L1 / AIO-K3-L2 and the Pro Bundles. Outbound path: base station or headset → outdoor speaker.
The base station runs in one mode at a time: POS Wireless (staff talk through the Main headset) or Fixed Mic (staff talk into the base station mic). The Listen-In headset is receive-only and cannot take orders. Confirm the mode and the headset label before anything else.
| # | Root cause | Fix |
|---|---|---|
| 1 | Wrong headset in use: the receive-only Listening headset is worn instead of the Main headset. On older systems both look identical. | Check the label on the headset; it must read “Main”. Keep the two on separate chargers or color-code them. |
| 2 | Main headset muted, unpaired, or volume down. | Clear mute, confirm it shows as paired (re-pair if not), raise the volume. Then check the POS headset volume and mute on the touch screen too. |
| 3 | Base station stuck in Fixed Mic mode while staff use the wireless headset. | Switch the base station to POS Wireless mode. |
| 4 | Touch-screen mute left on for the built-in speaker or gooseneck mic (for example after setup). | On the 5-inch screen, confirm the POS headset, gooseneck mic and built-in speaker are all unmuted and in Talk mode. |
| 5 | Base station fault: audio fails in both modes. | Run the isolation test below. If both modes fail after ruling out 4 and the ProPanel® auto-mute, contact support. |
| 6 | CAT5e cable between the speaker post and base station loose, damaged or not fully seated. | Reseat both ends; check for bent pins, corrosion or damage. Replace if damaged. |
Isolation test: wireless side or base station?
Switch the base station to Fixed Mic mode and speak into the fixed mic while someone stands at the speaker post.
- Driver hears you: the Fixed Mic path is good and the fault is on the wireless side. Verify the Main headset is in use, paired and unmuted, and that the base station is back in POS Wireless mode.
- Driver does not hear you: both modes fail. Rule out the touch-screen mute (cause 4) and the ProPanel® auto-mute at the post (is a vehicle present?). If both are clear, suspect the base station, the post-to-base wiring, or the outbound speaker. Contact support with the result.
Still not resolved? Send us: Photos of the outdoor speaker post (front and back), confirmation of the electrical connections, and a short video of an actual order attempt. Have your order number, purchase date and product ready. Download this guide as a PDF.
Applies to: Pro Intercom System AIO-K3-L1 / AIO-K3-L2 and the Pro Bundles. Inbound path: speaker post microphone → base station.
The speaker post houses two units in one factory-installed ProPanel®: the mic / substation at the top (inbound) and the speaker at the bottom (outbound). The built-in sensor unmutes both when a vehicle arrives and mutes them again about three minutes after it leaves; muting with no vehicle present is normal.
New installation? Start with the CAT5e cable (cause 2) and confirm the sensor detects a vehicle (cause 5). In service for a while? The weatherproof seal is the usual suspect (causes 3 and 4).
| # | Root cause | Fix |
|---|---|---|
| 1 | Speaker post location not per the installation guide (height, distance, angle). | Reinstall the post at the correct location and height per the guide. |
| 2 | Cable connection: CAT5e between post and base station loose, damaged or not seated. | Inspect and reseat both ends; replace the cable if damaged. |
| 3 | Weatherproof seal breach: moisture or debris has reached the mic. | Replace the outside speaker unit, or the whole post assembly if damage extends beyond the speaker. |
| 4 | Substation seal failure at the mic element. | Replace the substation (top mic unit). |
| 5 | Auto-mute not releasing: the ProPanel® sensor does not detect the vehicle, so the mic stays muted. | Confirm the sensor detects a vehicle arriving and leaving. If not, treat it as a sensor setup or placement issue before suspecting the mic. |
Quick check for cause 5: park a vehicle at the post. Within seconds the mic and speaker should go live; about three minutes after it leaves they should mute. If they never unmute, the problem is detection, not the microphone.
Still not resolved? Send us: Photos of the outdoor speaker post (front and back), confirmation of the electrical connections, and a short video of an actual order attempt. Have your order number, purchase date and product ready. Download this guide as a PDF.
Applies to: Wireless Headset System (Kit 2) and Pro Intercom System (Kit 3).
- Charge the headset fully first. A low battery is the most common reason a headset pairs and then drops.
- On Kit 3, confirm you are pairing the Main headset to the base station. The Listening headset pairs to its own transmitter/charging unit, not to the base station, and only receives audio.
- Confirm the base station is in POS Wireless mode; in Fixed Mic mode the headset is not used.
- Re-pair following the Kit 3 re-pairing guide (Kit 2: see the quick guide).
- Check headset mute and volume, then the per-device volume and mute on the base station.
- If the headset pairs but audio drops when you walk away, move the base station away from metal cabinets, Wi-Fi access points and other 2.4 GHz equipment, and keep it off the floor.
Still not resolved? Send us a short video of the pairing attempt and the base station screen, plus your order number and purchase date.
Kit 3 speaker post (ProPanel® sensor): the sensor is what unmutes the mic and speaker. Confirm it reacts when a vehicle pulls up and re-mutes about three minutes after it leaves. If it never reacts, check the CAT5e cable and the post position before suspecting the panel.
Vehicle Detector System (AIO-VDS), used with Kit 1, 2 and 3: a buried sensor wand connects to an outdoor transmitter, which signals the indoor receiver/chime wirelessly.
First check: does the transmitter LED flash when a car passes?
- Flashes, but no chime indoors: the wand is fine; the fault is on the wireless or receiver side. Move the receiver away from metal cabinets and other wireless equipment, make sure it is on an unswitched outlet, and check distance (rated up to 400 ft).
- Does not flash: the fault is on the wand, cable, sensitivity or battery side. Replace the transmitter battery, check the cable run and splice for water or edger damage, and adjust sensitivity.
Placement checklist
- Wand within 2 ft of the driveway edge, buried about 1 ft deep, at least 25 ft from the roadway and other traffic.
- About two car lengths ahead of the speaker post, where cars actually stop today (queue, paving or menu-board changes can move that spot).
- On a curved lane, install on the inside of the curve only.
- Keep the wand away from rebar, conduit, HVAC units, walk-in condensers and transformers; cycling electrical loads and buried metal cause misses and false triggers.
If only certain vehicles are missed (aluminum-body pickups, some EVs), that is a weak metal signature, not a fault; raise sensitivity slightly. If a detector keeps failing after parts have been replaced, the wand location is wrong for the site. See the Vehicle Detector Setup Guide.
Applies to: LED backlit menu boards (AIO-MBW-1P, AIO-MBF-1P, AIO-MBF-2P) and the Pro Bundles.
- Confirm power at the board: the outlet is live and unswitched, and the power supply LED (where fitted) is on.
- Check the connections between the power supply and the LED panel inside the housing; a plug that vibrated loose in shipping is the most common cause on a new board.
- One panel lit, one dark on a 2-panel board: swap the panel connectors to see whether the dark side follows the panel or the supply. That tells us which part to replace.
- Dim or flickering: check the supply voltage and for water inside the housing after heavy rain; confirm the housing gasket seats fully when closed.
- Follow the AV-90 setup guide for the panel and graphic installation steps.
Still not resolved? Send us photos of the inside of the housing with the door open, the power supply label, and a short video of the fault, with your order number.

Please check these possible installation errors, step by step:
| Step 1： | Error: | Wrong port is used. |
| Solution: | Ensure 3.5mm speaker wire is plugged into “OUT” port on the back of master station. (Not “MIC”, which is used for recording conversation with optional equipment.) | |
| Step 2: | Error: | 3.5mm plugs are not plugged-in completely at master station and speaker. |
| Solution: | Check all the plugs. | |
| Step 3: | Error: | Extension wires are disconnected during wire installation through conduit. |
| Solution: | Tape 3.5mm male end to female end before pulling wires through conduit. Prevent rain and excessive moisture. | |
| Step 4: | Error: | Speaker is installed too far from customers, too low from ground. |
| Solution: | Please see page 1 for proper speaker location. | |
| Step 5: | Error: | Headset is not paired properly to master station. |
| Solution: | Please refer to “Quick Start”. Pairing process is not complete until pairing confirmation announcement is heard over headset. | |
| Step 6: | Error: | Volume Control on master station is turned off. |
| Solution: | Turn the volume knob clockwise to max. | |
| Step 7： | Error: | MIC1 Push Button on master station is turned off. |
| Solution: | Ensure indicator light above MIC1 button is on. | |
| Step 8: | Error: | Mute function on headset is accidentally selected. |
| Solution: | Refer to “Quick Start”to unmute headset. | |
| Step 9: | Error: | SmartSpeaker® privacy feature is activated. |
| Solution: | SmartSpeaker® will automatically turn to mute mode 45 second after the previous customer leaves, until the built-in sensor detects the next customer. During testing, have a second person stand in front of speaker to unmute speaker. |
