Hold the Up and Down Buttons Simultaneously for 3 Seconds
To activate Shake Awake on the Holosun 507K, press and hold the up (+) and down (−) buttons together for 3 seconds until the reticle flashes. This motion-sensing feature conserves battery by dimming the optic when idle and reactivating it upon movement. Ensure firmware is updated for optimal performance.
Step-by-Step Activation Guide
- Power on the optic: Press either the up (+) or down (−) button to wake the reticle.
- Enter Shake Awake mode: Hold both buttons simultaneously for 3 seconds until the reticle blinks twice.
- Confirm activation: The reticle will flash once if successful. Shake the optic to test-it should dim after 5 minutes of inactivity and reactivate with movement.
- Disable (if needed): Repeat the button-hold process. The reticle will flash three times to confirm deactivation.
Troubleshooting Common Issues
- No response when holding buttons: Ensure the optic is powered on and batteries are charged (CR1632).
- Shake Awake not triggering:
- Check for firmware updates (outdated versions may lack the feature).
- Verify movement sensitivity-gentle shakes may not activate it.
- Reset by removing the battery for 10 seconds and retry.
- Reticle stays dim: Direct sunlight or bright light may override Shake Awake-test in moderate lighting.
Shake Awake vs. Other Power-Saving Modes
| Feature | Shake Awake | Auto-Brightness | Manual Always-On |
|---|---|---|---|
| Activation | Movement-based | Ambient light sensor | Constant reticle |
| Battery Life | Up to 50,000 hours | Up to 20,000 hours | Up to 10,000 hours |
| Ideal Use Case | Carry/concealment (intermittent use) | Outdoor shooting (variable light) | Competition (instant visibility) |
| Customization | Sensitivity fixed (firmware-dependent) | Adjusts automatically | Manual brightness control |
Pro Tips for Optimal Performance
- Test before carry: Shake the optic vigorously in a safe direction to confirm responsiveness.
- Avoid magnetic interference: Store away from strong magnets (e.g., phone cases, mounts) to prevent false triggers.
- Clean contacts: Use a dry cloth to wipe battery terminals if Shake Awake behaves erratically.
- Firmware updates: Check the manufacturer's site for latest versions-some add sensitivity adjustments.
When to Disable Shake Awake
- During competitions where instant reticle visibility is critical.
- In extreme cold (below -20°C/-4°F), as battery drain may increase.
- If using night vision-constant illumination may be preferred.
