Installation of a sound decoder including loudspeakers:
The steam locomotives of the series BR 99.2 are prepared for the subsequent installation of a sound decoder as well as a loudspeaker. To this end, for instance an ESU sound decoder can be used (Lok Pilot V4.0).
The interface Next18 according to NEM 662 is located under a cover in the driver’s cab. It is possible to install a loudspeaker under the printed circuit board in the area of the driver’s cab.
To install a decoder the driver’s cab has to be spread out slightly in the area of the surrounding step below the side windows and the driver’s cab must then be pulled off upwards. Following this, the coal imitation or the oil tank can be pulled off upwards with the cover under the driver’s cab window. The latching lugs are located in the area of the tender attachment.
Remove the boiler upwards
Pull off the coal / oil attachment upwards
Remove the water box (three detent mechanisms must be removed on each side to this end)
Detach the board:
|Following this detach the two screws of the circuit board and then lift off the board upwards||Now, the intended recess for the loudspeaker is visible and can be easily reached for the loudspeaker installation.|
Now place the printed circuit board correctly in the model again and carefully screw in both fixing screws. Then insert the digital sound decoder with a suitable sound recording (see above) into the Next18 interface.
Prior to this remove the interference suppression board located there. It should be taken out, as the Tillig customer service only accepts locomotives without a decoder for repair, if a repair should ever be necessary.
Now put the water boxes back on and press them into the detent mechanism. Following this attach the coal insert / oil tank and snap it into place. Now the boiler is put back on the chassis and if this sits correctly the cab is sensitively pressed back into its detent mechanisms. Finally push the smoke box door into the boiler from the front and snap it into place.
