Headset Use

The GLW headset is simple to use and requires no pairing or setup.

Power & Readiness

• The headset connects with a USB-C cable.
• Plug it into any USB power source (phone, tablet, USB charger, laptop).
• When powered, the headset is ready to connect to the GLW app using Bluetooth.
• You’ll see a faint blue front light - this indicates the headset is powered and waiting for the app.

Connection & Start

• When you tap Start in the app and choose to activate the headset, the app connects automatically.
• Once connected, the headset receives the PBM program definition and the start command from the app.

During a PBM Session

The headset uses clear color signals to show what part of the PBM program is running:

• Blue (strong) - cooling or rest periods
• Red (strong) - active PBM state
• Purple (strong) - “back of the head” periods with different parameters

Most PBM programs have an active state lasting 10-20 minutes, depending on what is assigned to the user.

Repositioning Guidance

Some PBM programs include repositioning steps.

When repositioning is needed:

• The app plays an audible signal.
• The bottom drawer shows instructions such as: Front, Left, Right, Back.

You simply move the headset to the indicated position and continue.

Cleaning

• Wipe gently with a soft cloth.
• Avoid liquids entering any openings.

Troubleshooting

In almost all cases, issues are Bluetooth-related:

• Make sure Bluetooth is turned on on your phone or tablet.
• Check that the headset is flashing faint blue (ready state).
• If not flashing:
  • Try a different power source.
  • Try a different USB-C cable (they can fail).
• If the app doesn’t detect the headset:
  • Close the app completely and restart it.
  • If still not working, reboot the phone.

These steps resolve nearly all connection issues.
