Step 1: Move to an Open Outdoor Area

GPS requires a clear view of the sky to communicate with satellites.

Follow these steps:

1. Go outdoors.
2. Move away from buildings and large structures.
3. Avoid areas with heavy tree coverage.
4. Keep your watch facing upward.
5. Wait for GPS connection before starting your activity.

Avoid testing GPS:

• Inside buildings
• Under bridges
• Near large metal objects
• In underground locations

A clear environment improves satellite reception.

Step 2: Wait for GPS Lock Before Starting Activity

Starting an activity before GPS connection is complete can cause tracking errors.

To get a stronger signal:

1. Select your workout mode.
2. Wait until GPS connects.
3. Confirm satellite detection.
4. Begin your activity.

Allowing the watch to lock satellites improves accuracy.

Step 3: Restart Your COROS GPS Watch

A restart can fix temporary GPS communication problems.

Steps:

1. Press and hold the power button.
2. Turn off your COROS watch.
3. Wait a few seconds.
4. Turn it back on.
5. Test GPS outdoors.

Restarting refreshes the GPS system and device software.

Step 4: Sync COROS Watch With the App

Synchronization can refresh GPS-related information.

Follow these steps:

1. Open the COROS app.
2. Enable Bluetooth.
3. Connect your watch.
4. Allow synchronization to complete.

Regular syncing helps keep your device data updated.

Step 5: Refresh COROS Satellite Data

Old satellite assistance data can slow GPS connection.

To refresh:

1. Open the COROS app.
2. Connect your watch.
3. Complete a full sync.
4. Keep Bluetooth enabled.
5. Allow GPS information to update.

After refreshing, test GPS in an open area.

Step 6: Update COROS Firmware

Outdated firmware can cause GPS signal problems.

Firmware updates may improve:

• Satellite connection speed
• GPS accuracy
• Tracking stability
• Navigation performance

To update:

1. Open the COROS app.
2. Select your watch.
3. Check for firmware updates.
4. Install the latest version.
5. Restart your device.

Step 7: Update the COROS App

An outdated COROS app may affect communication between your phone and watch.

To update:

1. Open your phone’s app store.
2. Search for COROS.
3. Install the latest version.
4. Reconnect your watch.

Keeping the app updated helps prevent synchronization issues.

Step 8: Check COROS GPS Mode Settings

Incorrect GPS settings may reduce signal performance.

Review:

• GPS mode
• Activity profile
• Accuracy settings

Recommended settings:

• Use high-accuracy GPS mode.
• Enable dual-frequency GPS if supported.
• Avoid reduced GPS accuracy options.

Step 9: Disable Battery Saving Mode

Battery-saving features may limit GPS performance.

Check settings for:

• Low power mode
• Reduced GPS tracking
• Battery optimization

For stronger GPS:

• Charge your watch.
• Use normal or high-performance GPS settings.
• Disable unnecessary power-saving options.

Step 10: Reset COROS GPS Settings

If signal problems continue, resetting the watch may help.

Before resetting:

• Sync your activities.
• Save routes.
• Backup important data.

Reset steps:

1. Open watch settings.
2. Select reset options.
3. Confirm reset.
4. Pair the watch again with the COROS app.

A reset can fix incorrect settings affecting GPS performance.

Step 11: Check for Hardware Problems

If your COROS GPS signal remains weak after troubleshooting, hardware damage may be the cause.

Possible signs:

• GPS never connects outdoors
• Signal drops constantly
• Watch was physically damaged
• Location remains inaccurate after reset

Contact COROS support if hardware failure is suspected.
