1. ESD--which means Electro Static
Discharge. This is what occurs when you walk across a carpet and
touch a piece of metal and get a shock. Before touching the HQ sound
board You should touch something that is grounded to discharge
static electricity you may be storing. This is important to do with
any bare electronic circuit boards you handle.
2. The HQ circuit boards can be installed
in buildings, under the layout, and onboard trains where room
permits. You can use velcro, double back tape, or just laying the
board down in a building.
Caution, do not lay the board
down on any metallic surfaces or permanent damage will
result.
3. If used outdoors, it will be necessary
to weather proof the circuit board, speaker, and any other
electronics to protect them from the elements.
4. For increased sound quality, speakers
should be baffled. This can be done as easy as by putting it in a in
a small cardboard with holes in the front. You can also use
cardboard or PVC tubes, or if it is in a building, that will act as
a baffle.
5. Specifications: Power requirements. 9
to 18 volts DC or 4 to 18 volts AC. Current Drain is approx. 10ma
