6. Operation
6.1 Power On/Off and Brightness Adjustment
The sight features a rotary switch for power and brightness control.
- Rotate the dial to turn the sight ON.
- The dial has settings for 'R' (Red) and 'G' (Green) illumination, each with 5 brightness levels (1-5).
- Select 'R' for red reticle or 'G' for green reticle.
- Rotate the dial further to increase the brightness level (1 being the dimmest, 5 being the brightest).
- To turn the sight OFF, rotate the dial to the '0' position.
6.2 Reticle Selection
The RDSL15 Z1 offers four different reticle patterns. A selector switch, typically located near the objective lens, allows you to cycle through these patterns.

6.3 Windage and Elevation Adjustment
The sight features windage (horizontal) and elevation (vertical) adjustment turrets to zero the sight to your firearm.
- Remove the protective caps from the windage and elevation adjustment turrets.
- Use a flathead screwdriver or the provided adjustment tool to turn the turrets.
- Elevation Adjustment: The top turret adjusts the vertical point of impact. Turning it clockwise typically moves the point of impact down, and counter-clockwise moves it up.
- Windage Adjustment: The side turret adjusts the horizontal point of impact. Turning it clockwise typically moves the point of impact right, and counter-clockwise moves it left.
- Each click of the turret corresponds to 1 MOA (Minute of Angle) adjustment.
- Perform adjustments carefully while zeroing your sight at a shooting range.
- Once zeroed, replace the protective caps.
7. Maintenance
