Preliminary Alignment - Bosch D296 Installation Instructions Manual

6.0 Setup
Before performing a setup, ensure all connections are
made and secure. Then, apply power to the transmitter
and receiver.
1. Press the transmitter's Aim Mode button, located
above the green LED (refer to Figure 9) allowing it
to power up while the cover is off.

2. Ensure the green LED flashes on and off. If this
LED is off, check for power and proper polarity on
Terminals 1 (–) and 2 (+). If the green LED is
steadily lit, you have a faulty transmitter. Return the
transmitter to the factory.
3. Check the three receiver LEDs (refer to Figure 10).
It is normal for all three LEDs to be on at this time,
with the green LED either flashing or steadily on.
If all LEDs are off, check for power and proper
polarity on Terminals 8 (–) and 9 (+).

2 - Trouble LED (yellow)
3 - Normal LED (green)
4. Mount a D309 Strobe Aiming Light or an
equivalent, such as a Faraday 5508, as close to the
receiver as possible, preferably on top of the
receiver.
5. Point the D309 at the transmitter using it as your
aiming guide. An aiming light might not be
necessary for short distance separations.

Preliminary Alignment

Each optical module has two alignment mirrors, one on
each side, for an initial alignment (refer to Figure 11).

3 - Horizontal fine tune
4 - Side view
1. Look into either mirror from a side angle that is a
minimum of 2 ft (61 cm) from the module.
The optical module points at objects seen in the
mirror when the orange-colored front bore sight is in
the center of the rear bore sights (refer to Figure 12).
Use the rear and front sights in the same way as you
use sights when aiming a gun.

2. Rotate the transmitter's optical module left or right
until you see the aiming light image (or receiver
image, if aiming light is not used) in the mirror.
3. If optical module is initially aimed too high or too
low, adjust the Vertical Fine Tuning adjustment Allen
screw (with the supplied Allen wrench) slightly up or
down until you see the image.
4. Use the Vertical Fine Tuning adjustment screw and
the Horizontal Fine Tuning adjustment screw to fine
tune the image to the center of the mirror (aligned
with the front and rear bore sights).
5. Replace and secure the transmitter's cover.
6. Ensure the transmitter's green LED is flashing.
7. Replace and secure the transmitter's access door.
