How do I reset shake-awake on a Holosun HS507C X2 sight?
Answer
Shake-awake problems on an HS507C X2 are usually fixed by a full on-device reset of the sleep timeout, then leaving the sight powered so the setting can save correctly.
Before you start: stop right away if…
- Always treat firearms as loaded and keep the muzzle pointed in a safe direction while adjusting an optic.
Follow these steps
Install fresh batteries
Replace the sight battery with a fresh one of the correct type and reassemble the battery tray fully.
You should see: The sight powers on normally with the reticle visible when turned on manually.
Turn the sight on
Press the power or brightness button to turn the sight on so the reticle is lit before changing sleep settings.
You should see: The reticle is on and button presses register.
Set and save the sleep timeout
Use + or - to change the sleep or shake-awake timeout, then press + and - together to save the setting according to Holosun’s button sequence for the X2.
You should see: The sight accepts the save action and returns to a normal display state.
Power cycle and test shake-awake
Turn the sight off and back on with either button, leave it on long enough to sleep, then move the firearm or optic to test wake-up.
You should see: The reticle wakes from sleep when the sight is moved.
