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

  1. Power on the optic: Press either the up (+) or down (−) button to wake the reticle.
  2. Enter Shake Awake mode: Hold both buttons simultaneously for 3 seconds until the reticle blinks twice.
  3. 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.
  4. 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    • Check for firmware updates (outdated versions may lack the feature).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.
