Actual size mounting template to assist in mounting the switch / volume (sw/vol-h) control board.
Mounting Templates for LocoMatic™ SwVol Board
Selector Switch & Volume Control Board.
Mount with tape supplied in a convenient location, or use
other double sided tape, or small screws. Be sure not
to allow any metal parts to contact any parts or traces
on the board, this will damage the system. This board
is connected to the Main Board with a 9 pin wire
harness to allow for a more convenient placement.
Rotating the "VOL" (volume) control clockwise will
increase the volume. A complete counter-clockwise
rotation will yield no sound!
Note: It is possible to destroy a standard round speaker
when operating at higher volumes. This is especially
true with EMD type sound systems. The sound system
contains a 1 watt audio amplifier and the standard
speaker is capable of sustaining 0.2 watts continuous.
The standard speaker is a high efficiency type. You can
connect two standard speakers in series to obtain
higher volumes with less damage to the speakers.
