Model
Objective Lens
A canted objective lens is part of the design of reflex/reflective optical sights. In order to create a proper reflection of the reticle/dot the objective lens must be perpendicular to the LED.
Because the LED is mounted to the base of the optic the objective lens will be canted back, towards the LED.
Features
1) Automatic reticle intensity adjustment in Auto Mode.
2) 32MOA circle and dot, 2MOA dot only and 32MOA circle only.
3) Shake AwakeTM – Motion on with last setting recall.
4) Parallax free, unlimited eye relief.
5) Drain holes on both sides of the optic allow for excess water to escape during wet conditions.
6) Solid Titanium Body.
7) 12 Brightness Settings: 10DL & 2NV.
8) Window Size 0.63 x 0.91 inches.
9) Waterproof: IP67
Multi Reticle
The default reticle for this sight is a 2MOA dot centered in a 32MOA circle with four positioning points. The diameter of the circle reticle represents approximately 32″ at 100 yards (81cm at 100 meters). Hold the “-” button down for 3 seconds to switch between the three reticle options, Circle+Dot, Dot-only and Circle-only, in that order.
Battery
The 508T operates with our Solar Fail Safe™ dual power system (solar cell and internal battery). One high quality CR1632 Lithium battery is included with purchase.
A high quality battery can power this device for up to 20,000 hours (circle dot), or 50,000 hours (dot-only) at setting 6. Caution: Do not use a rechargeable battery.

Sight Operation
Three operation modes are available: Auto mode, Manual mode and Lock mode, (See Fig 6).
1. Power ON; Momentarily press either button (“+” or “-“) to turn on the sight.
2. Power OFF: Press the “+” and “-” buttons simultaneously to turn the power and motion sensor off, Shake Awake is disabled when OFF.
3.Operation Mode: Three modes are available in the following order Auto Mode -> Manual Mode -> Lock Mode.
1) Auto mode: In Auto mode, the solar cell and internal battery (two way power supply) powers the sight. The reticle brightness is automatically adjusted based upon ambient lighting conditions. Switch between battery and solar cell power automatically. Auto mode accommodates operation in all lighting conditions. Auto mode is the default setting.
a) In auto mode, the brightness of the reticle is automatically adjusted to match ambient lighting.
b) The battery will compensate for power if the solar cell cannot drive the reticle alone.
c) RED: If lighting is low enough, the sight will automatically switch to battery power. While running on battery power, you can adjust the reticle brightness using the “+” and “-” buttons to switch between higher and lower brightness levels.
d) GREEN: There are 8 settings from 3-10 under auto modes which have same brightness of manual modes. Press “+” or “-” to adjust the brightness and you are at setting X, the brightness will vary from X to 12 according to ambient lighting.
2) Manual mode:
a) Switch to Manual mode from Auto mode by holding the “+” button for about 3 seconds, until the reticle blinks once.
b) Brightness adjustment: There are 12 reticle brightness setting levels in manual mode. Settings 1 and 2 are NV compatible and setting 12 is the brightest. Press “+” or”-” to increase or decrease the brightness.
3) Lock Mode: Switch to Lock mode from Manual mode by holding the “+” button for about 3 seconds, until the LED blinks once. In Lock mode, momentary presses of the “+” or “-” button will not change settings. To exit the Lock mode, press and hold the “+” button again for 3 seconds, the LED will blink once then switch to Auto Mode.
4. Sleep Timer setting:
1) Please note that your red dot will automatically enter into sleep mode after 10 minutes of no movement.
2) The sight will instantaneously wake up and turn on with any motion detected and return to the last saved settings.
3) The default sleep timer setting is 10 min, but there 4 user selectable sleep timer options.
i. Press and hold the “+” button for 10 seconds to access sleep timer settings. There are 4 setting options: 10 min, 1h, 12h or the sleep mode is disabled.
ii. Press and release the “+” or “-” button to select a sleep timer setting. The LED will blink to show which setting is selected: 1=10 min, 2-1h, 3-12h or 4-sleep mode disabled.
iii. Press the “+” and “-” buttons simultaneously to save the sleep timer setting (this will power off the sight).
5. Special operation:
1) Solar cell power: If the battery voltage is below 2.2V, please replace it. The sight will still operate if there is sufficient ambient light for the solar cell.
2) To reduce power consumption when you have low battery and/or low ambient light, you can toggle the 32MOA circle OFF by holding the “-” button for about 3 seconds.
6. Note:
1) Memory function: The sight will remember the last saved brightness setting when powered on and off.
2) Low battery Warning: If the battery voltage is below 2.2V, the reticle will blink siowly.
Zero Setting
1) This sight has been factory adjusted to an approximate 25 yard zero and should require minimal adjustment to achieve zero.
2) The Elevation adjustment is located on top of the tail section of the housing and the Windage adjustment is located on the right side of the housing. Adjustment can be performed by inserting the flat-tipped end of the included tool into the turret slot and rotating, (See Fig 7).
3) Windage and Elevation adjustments are approximately 1 MOA per click.
4) Each adjustment click has a value of approximately 1 MOA or 1 inch at 100 yards (1/2″ at 50y; 1/4″ at 25y). When zeroing at 25 yard, if your impacts are 2 inches low and 1 inch right, you will need to adjust Elevation 8 clicks UP (counterclockwise) and 4 clicks LEFT (clockwise)
5) The maximum adjustment range is +50MOA from center. Caution: If you feel the knobs can Elevation no longer be rotated, you may have reached the mechanical limit of the adjustment turret.
Do not try to rotate the knobs further, if you feel a bind or you may cause damage.
