Product Description
The WakeCap Anchor Node (WC-NODE-A) is a fixed wireless mesh router designed for deployment on construction and industrial sites. It enables network coverage extension and improves positioning accuracy of helmet and asset nodes within the 2.4 GHz WakeCap mesh. Anchors are strategically installed based on project size, coverage, and density requirements.

Battery Replacement
Battery Type: 3.6V 19Ah ER34615 Lithium D-cell (non-rechargeable)
Estimated Life: 10–12 years depending on reporting interval
Replacement Steps:
- Move device to a designated safe maintenance area.
- Unscrew the four stainless steel M4 hex screws on the enclosure (torque 1.5 Nm).
- Remove enclosure cap and carefully disconnect PCB JST battery connector.
- Remove depleted D-cell.
- Insert new D-cell in correct polarity orientation.
- Reconnect JST cable to PCB battery connector.
- Ensure gasket is properly seated before resealing the enclosure.
- Tighten M4 screws to 1.5 Nm torque.
- Verify boot-up by tapping the device with NFC to read status.
Notes: Use ESD-safe tools and dispose of lithium batteries properly.
Cleaning Instructions
- Use soft cloth with mild soap and water.
- Do not use solvents, alcohol-based cleaners, or abrasive pads.
- Ensure humidity membrane is kept clear of debris.
Firmware Updates
Firmware is not user-updatable. If required, updates are deployed remotely via the mesh.
For update verification, contact WakeCap support.
Troubleshooting Guide
| Symptom | Possible Cause | Solution |
| Anchor offline | Battery depleted | Replace D-cell (Section 4.2) |
| Out-of-network coverage | Reposition closer to anchors/gateway | |
| Water ingress/hardware fault | Quarantine unit, contact support | |
| Weak signal | Poor antenna placement | Reinstall higher, away from metal |
| Intermittent operation | Low battery / unstable link | Check the dashboard, replace battery |
| High interference | Review anchor density, reposition | |
| NFC not reading | Dirt or surface obstruction | Clean NFC area |
| Antenna damage | Inspect, replace if needed |

FCC Warning Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to operate this equipment.
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
The device has been evaluated to meet general RF exposure requirement.
