OPERATING INSTRUCTIONS
Active 16V Antenna BRT-10133
°
Order No. 37 34 73
This product complies with all current National and European requirements
Intended Use
The active 16V antenna is used to receive and to amplify analogue and terrestrial radio signals.
This product may only be operated if it is connected to a 12V DC car power supply with the
negative terminal of the car battery connected to the body. It may only be installed and operated
in vehicles supplied with this kind of voltage.
Any use, other than that described above, may lead to damage to this product and involves other
risks, such as short circuit, fire, electric shock.
Always observe the safety instructions.
Safety Instructions
The warranty will be void in the event of damage caused by failure to observe
these safety instructions! We do not assume liability for any resulting damage.
Nor do we assume liability for damage to property or personal injury caused by
improper use or failure to observe the safety instructions. In such cases the
warranty will be null and void.
This symbol indicates important information in the instructions. Prior to
starting up the product, read the operating instructions entirely; they contain
important information on the correct operation.
• For safety and licensing reasons, unauthorised conversion and/or modifications to the product
are not permitted.
• The device may only be used with a 12 V DC vehicle power supply (with the negative terminal
of the battery connected to the body of the vehicle). Never connect the antenna to any other
voltage supply.
• If you have doubts about how the equipment should be operated or how to safely connect it,
consult a trained technician.
• Do not leave packing materials unattended. It may become a dangerous plaything for children.
• Please, also observe the additional safety instructions in each individual section of these
instructions.
Mechanical Installation
Modifications to the vehicle which are made necessary due to the installation of
the antenna must always be carried out in such a manner that neither the traffic
safety nor the designed stability of the car is impaired.
If you are in doubt, when selecting a place for installation, consult your car
dealer.
Make sure, before drilling the attachment holes, that no electric cables, brake
cables or similar can be damaged.
Be sure to follow the safety instructions of the tool manufacturer, when using
tools to install your antenna.
The antenna should be mounted to the front or rear areas of the car roof. A 14mm hole is
necessary for mounting.
• Within the mounting area remove the headliner, and existing consoles, covers or the like,
respectively.
• Make sure that there is sufficient space for the antenna base below the mounting hole.
• Place a piece of duct tape on the drilling point. This prevents the borer form sliding and the car
finish from splitting when drilling. In addition this facilitates marking of the drilling point.
• Drill a mounting hole of 14mm diameter into the mounting surface (1). To do so, use a suitable
sheet metal borer.
• Protect the mounting hole from corrosion by applying lacquer or an anticorrosive to the edges.
• Remove the mounting nut (4), and all washers and rubber bushings from the mounting base
of the antenna.
• Spread a little chassis sealer around the edge of the mounting hole in order to have the hole
cleanly sealed with the antenna screwed in place.
• Lead the cable of the antenna through the mounting hole and reattach the antenna as shown
on the following image. The plastic ring (2) must be snapped in into the hole in order to protect
the cable from damages by the sharp edge of the hole.
• Set the serrated washer (3) under the mounting nut (4) so that the teeth pointing upwards to the
mounting surface (1) and the flap of the washer (3) is in the recess at the antenna thread. The
teeth make contact with the mass of the mounting surface (1). This is very important for good
radio reception. If necessary, you might want to remove the car finish in this area.
• Align the antenna straight and tighten the mounting nut (4).
• Protect the bottom of the mounting surface (1) from corrosion with some grease.

Connection
To avoid short circuits and any resulting damage to the antenna, the negative
terminal (earth) of the car battery has to be disconnected first.
Before reconnecting the negative terminal to the battery, ensure that the aerial
has been completely connected and the connection checked.
Only use a volt meter, or a diode test lamp, to check the voltage of the vehicle
system leads, as normal test lamps consume excessive voltage and may thus
damage the vehicle’s electronics.
When installing the cables, ensure that these are not squashed or scraped on
sharp edges! Use rubber bushings at cable insert points for penetrations.
Do not lay cables in the triggering area of air bags.
• Connect the antenna plug of the black antenna line with the antenna input of your car radio. To
do this, use an antenna extension cable. Do not cut through the antenna cable. This leads to
losses of signal.
Should your car radio have a different connection standard, use an adapter plug which can be
acquired in a specialist shop.
• Connect the thin, red cable to the antenna control output of your car radio. The built-in antenna
amplifier then turns on automatically when switching on your car radio.
Should your car radio not have such connection, connect this cable with the connector that
carries +12V while the ignition is switched on.
Cleaning
If you wash your vehicle in a car wash, please remove the antenna rod. This prevents damage
to the vehicle and the antenna. The rod can be unscrewed easily counter clockwise.
After washing you can screw it back on in a clockwise direction.
Protect the thread of the antenna rod with some grease from corrosion after every wash.
Otherwise, the thread of antenna rod could corrode and no longer be removable from the foot
without damaging the antenna.
Disposal
Dispose of the product in accordance with the legal regulations that apply.
