3.3 Aiming the DSR1090

When aiming the DSR1090, you can use a laser for accuracy.

3.3.1 Using a laser for horizontal aiming

Instructions are provided for horizontal aiming using a laser.

About this task
This tool is required for horizontal aiming:
• Installer-provided laser pointer
Procedure
1. Place the laser pointer on the outside left or right side of the DSR1090 enclosure.
2. Align the laser parallel to the side of the speaker. You may find that there is some vertical (up/down) drift,

but this will not affect how you obtain the horizontal angle.

3. Angle the DSR1090 horizontally until the laser is directed at the specified aiming point.

3.3.2 Using a laser for vertical aiming

Instructions are provided for vertical aiming using a laser.

About this task
This tool is required for vertical aiming:
• Installer-provided laser pointer
Procedure
1. Place the laser pointer on top of the DSR1090 enclosure.
2. Align the laser level with the top of the speaker. You may find that there is some side-to-side drift, but this

will not affect how you obtain the vertical angle.

3. Angle the DSR1090 vertically until the laser is directed at the specified aiming point, as shown in the

following figure.
