The battery icon on the display will switch to the plug icon. The riflescope is now operating using the external power only.

Note: When AA batteries are in the unit and an external power source is used, the unit operates on the external power source only. When the unit is disconnected from a power bank or external power supply, the Photon will automatically switch to internal batteries. When using rechargeable AA batteries in the Photon RT, plugging the Photon RT into an external power source DOES NOT recharge the batteries in the unit.

Sightmark Riflescope SM18018 Mounting

The Sightmark Photon RT riflescope requires 30mm scope rings (not included) for mounting. Mount the scope per the scope ring manufacturer’s instructions. Do not perform a final tightening of the rings prior to checking eye relief and reticle alignment. Initially the riflescope should still be able to move for and after and rotate when installed in the rings.
To achieve maximum eye relief:

Turn the Photon RT on and focus the image. Set the riflescope far forward in the rings and slowly move the riflescope closer to your eye. Stop moving the riflescope once a full field of view is visible.
Next rotate the scope to vertically align the crosshair. Use a reticle leveling tool if available.
Once alignment is complete, tighten the mounting ring’s screws evenly so the gap is even on both sides of the scope. Do not over tighten.

Warning! If the riflescope is not setup correctly with proper eye relief and is mounted too close to the shooter’s eye, it’s rearward motion due to firearm recoil may cause injury to the shooter. To zero the scope, see section “One Shot Zeroing”.
