Operating Instructions
Engine Sound Simulator
Item No. 1342319
Intended Use
The product is used to generate engine noises for electrically operated model vehicles. The
sound simulator is protected against sprayed water and can be used in your model as soon
as it is connected.
With a USB adapter, included in the package, and special software (latest version always
available as a download at www.conrad.com on the webpage for the product), you can adjust
the pre-installed motor sound files as you wish.
The safety instructions and all other information in these operating instructions must be obser-
ved at all times.

• For safety and approval reasons (CE), unauthorized conversion of and/or changes to the
product are not permitted. Never dismantle it!
• The product is not a toy and should be kept out of the reach of children.
• The sound simulator can achieve volumes that can cause hearing damage to people and
animals. During testing and driving operation, make sure to keep sufficient distance from the
speaker.
• Do not leave the packaging material lying around carelessly, since it could become a dange-
rous plaything for children.
Product Description
1 Servo Y cable
2 Servo plug for control
3 BEC connection for power supply of the amplifier
4 Adapter cable with T-plug/-socket for power supply of the amplifier
5 2x adhesive pads for attaching the sound simulator
6 USB adapter for changing the sound files
Installation
The sound simulator must be mounted in your model vehicle such that it is firmly attached
during the driving operation. The housing can be attached, e.g., with the adhesive pads from
the package (see Fig. 1, Pos. 5) or alternatively with cable ties (not included).

The sound simulator is protected against spraying water. However, the housing opening of the
sound simulator must point downward.
The higher the volume is set, the warmer the electronics and also the built-in speaker will

become. Therefore, pay attention to sufficient cooling when installing.
Connection
Connect the Y cable (1) with the plug to the receiver output intended for the speed controller.
Connect the plug of the speed controller and the plug of the sound simulator (2) to the two
sockets of the Y cable.
A two-pin cable with BEC plug (3) is fed out of the housing for the power supply of the ampli-
fier. Connect this plug to the adapter cable (4). Plug the high-current connection of the speed
controller to the T-socket of the adapter cable; the T-plug of the adapter is then connected to
the drive battery.
The electronics of the sound simulator are supplied with power via the BEC of the
speed controller (BEC voltage 4 - 8 V/DC required); because of the high power con-
sumption during the sound playback, the amplifier is supplied with power directly from
the drive battery (5 - 26 V/DC).
The amplifier must not be operated via the BEC of the speed controller, but rather
directly via the drive battery.
Attention, important!
In principle, the sound simulator is designed for operation with a 2 – 3-cell LiPo drive
battery (or a 5 – 9-cell NiMH drive battery).
Operation with a rechargeable battery with more cells is possible, but in this case, the
volume control must not be set beyond the fifth level. Failure to observe this limit can
destroy the speaker due to overloading! Loss of warranty!
Adjustment Options
a) Programming neutral and full throttle positions for driving forward/in rever-
se
Attention!
For these adjustment tasks, the respective full throttle position for driving forward and
in reverse must be controlled at the transmitter.
To avoid accidents or injuries, the model must therefore be placed on a suitable
base so that the wheels can turn freely. Hold the model still or secure it in a suitable
manner. However, do not reach into the drive!
Alternatively, disconnect (if possible) the motor from the speed controller.
Before the initial start-up, the sound simulator must be programmed for the neutral and full
throttle positions for driving forward and in reverse.
To do this, proceed as follows:
• If you have not already done so, connect the sound simulator correctly; see section "Connec-
tion".
• Switch on the transmitter. Then switch on the drive battery. Switch on the speed controller.
• Press and hold the "+" button for more than 1 second, until the sound simulator beeps. The
simulator is now in programming mode. Release the "+" button.
• Make sure that the lever for the motor control function on the transmitter is in the neutral
position (release lever, and do not move it).
Confirm this setting by pressing the "+" button again until the sound simulator beeps.
• Move the lever for the motor controller to the full throttle position for driving forward and hold
it still in this position.
Confirm this setting by pressing the "+" button again until the sound simulator beeps.
• Move the lever for the motor controller to the full throttle position for driving in reverse and
hold it still in this position.
Confirm this setting by pressing the "+" button again until the sound simulator beeps.
• Bring the lever for the motor controller back to the neutral position (release the lever).
The programming is confirmed by a long beep. Should the sound simulator beep multiple
times, the electronics have not recognized the settings. In this case, repeat the programming
process described above.
The programming can be interrupted by pressing the "-" button. This is signalled by a long
beep.
