5. Connect Bluetooth Bridge (BTB)

To control your lights with the AsteraApp,
first connect a Bluetooth Bridge (BTB). It
forwards the AsteraApp signal to paired
lights. You may use an AsteraBox as BTB
or choose a light with built-in BTB, like
LeoFresnel, AX9, NYX Bulb, PixelBrick,
Titan Tube BTB, Helios Tube BTB.

Connect AsteraBox as BTB

Please power on the AsteraBox. Connect
the AsteraBox directly from the AsteraApp

) main menu by following the instructions
there.

Linking via linking key

Alternatively, LeoFresnel can also be connected to a CRMX transmitter using a
linking key, provided that the transmitter supports this linking option. To set a
linking key, navigate in the main menu to ,DMX SETTINGS”. Under ,CRMX LINK
BY KEY” you can enter the desired eight-digit combination

8. Reset
RESET sets Input Select” to ,AUTO” and runtime to 5 h.

9. Charging and DC wiring

While the power cable is connected, the display shows the charging status. Charge
immediately when the battery is empty. Do not store the unit when the battery is

empty. In addition to the powerCON TRUE! input/output connectors, the LeoFresnel
also has a 3Pin XLR input for use with external DC sources. The external DC input
will accept voltages from 12VDC to 48VDC. The external DC source should be
able to supply at least 250W. If you are using two RuntimeExtenders to power
the LeoFresnel via the external DC input, you must use 14.4V batteries only. The
polarity for the external DC input is Pin 1 Ground, Pin 2 DC+. Pin 3 is not used. It is
not possible to charge the internal battery via the DC input.

10. Rigging

The LeoFresnel is equipped
with AirlineTracks on all four
sides to attach various Astera(
mounting accessories. When
installing accessories on the

audibly click into place!

With the included yoke, LeoFresnel can be easily
hung. When hanging, always secure with a safety
wire at the safety eyelet on top of the light’s housing
Make sure the light cannot drop more than 20cm if primary mounting fails.
the Leo Fresnel can also be mounted on tripods. For this purpose, a TVMP (TV to motion picture) adapter
that can be attached to the yoke of the Leo Fresnel is included with the product.

Yoke (AF250-YK) attachment with Yoke Base (AF250-YKB) – Quick Release

Base lock

To attach the Leo Fresnel yoke, the two Yoke Bases must first be
inserted into the Airline Tracks on opposite sides. To secure the
Yoke Base, turn the Base Lock clockwise.

The scales in the Airline Tracks help to ensure that the same
position is selected on both sides. There is a default position for
the YokeBase.

You can move the YokeBase to balance the light or to a different configuration. NPE

It is important that the YokeBase
is oriented so that the opening of the V points downward. When the light is properly
prepared, the yoke can be inserted into the Yoke Bases from the bottom up.

The yoke is attached to the YokeBases
with a Quick Release system. To release _
the yoke, first loosen the Tilt Lock. This
acts as a safety for the Quick Release
Once the Tilt Lock is loose, press the
Quick Release buttons on each YokeBase
to release the fixture from the Yoke. Make
sure to hold the fixture securely while,
releasing it
