Inbound Diagnostic

Upon receiving a WanderBaby unit for diagnostic purposes, follow these step steps to assess its condition and determine necessary repairs or replacemen replacements:

1. Visual Inspection:

• Check for visible signs of damage such as cracks, dents, or liquid int

intrusion marks.

• Ensure that the privacy shutter and mic-kill switch function correctly

correctly (shutter covers lens, switch mutes microphone).

• Inspect LED indicators for correct functionality.

2. Functional Testing:

• Power on the unit and verify that it boots successfully without error

messages.

• Check video quality in 1080p HDR mode (for WV-BABY-STD) or 4K HDR mode

mode (for WV-BABY-PRO).

• Ensure audio quality is clear with stereo MEMS mic recording.
• Test breathing motion detection functionality and ensure it works accu

accurately without false positives.

3. Software Assessment:

• Verify that firmware is up-to-date and matches the expected version ba

based on the unit's SKU.

• Run a diagnostic test to check for any software bugs or issues affecti

affecting system stability.

• Confirm compatibility with supported third-party platforms (HomeKit Se

Secure Video, Google Nest) if applicable.

4. Environmental Testing:

• Ensure that the unit meets environmental standards (FCC Part 15, FCC P

Part 18, CE EMC).

• Test for electromagnetic interference (EMI) and ensure it operates wit

within acceptable limits.

• Confirm battery safety compliance with IEC 62133.

• Power up the device to confirm proper operation with the new battery.

Firmware Roll-Back

In cases where a firmware update causes issues, roll-back procedures are ne necessary:

Pre-Rollback Checks

1. Backup Data: Ensure any critical user data is backed up locally or e externally before proceeding. 2. Verify Version Compatibility: Confirm that a previous stable firmwar firmware version exists and matches the device SKU.

Roll-Back Procedure

1. Download Correct Firmware:

• Obtain the correct version of firmware from official sources.

2. Prepare Device for Update:

• Power off the device completely and connect it to a computer via USB.
• Place the device into update mode by holding specific buttons during b

boot-up (refer to user manual).

3. Install Firmware:

• Transfer the downloaded firmware file directly onto the device's stora

storage space through the connected PC.

• Initiate installation using proprietary software or manual process as

per documentation.

4. Post-Installation Checks:

• Power on the WanderBaby and verify that it boots successfully with rev

reverted firmware settings.

• Run diagnostics to confirm all features work correctly post-roll-back.

post-roll-back.

Decommission + Secure-Wipe

Decommissioning a WanderBaby involves securely wiping data from the device and safely disposing of hardware components:

Data Wiping Procedure

1. Panic Button Activation:

• Press and hold the panic button combination (referenced in user manual

manual) to erase all recordings.

2. Factory Reset:

• Execute a factory reset through software or physical buttons, ensuring

ensuring that no residual data remains.

3. Verifying Wipe Success:

• Power on the device post-reset and confirm it starts as new with defau

default settings.

Hardware Disposal

1. Remove Battery: Unscrew or unclip battery pack WB-BAT01 for recyclin recycling. 2. Disassemble Cover: Carefully remove back cover to expose main compon components. 3. Component Removal:

• Safely detach and store all FRUs (lens assembly, microphone, radar mod

module) for potential reuse or proper disposal.

4. Mainboard Destruction:

• Physically destroy the mainboard by breaking it into pieces using safe

safe methods that prevent data recovery. 5. Documentation Retention:

• Keep a record of destruction and disposal actions in compliance with e

environmental regulations and company policy.
