56. When power is turned off, the sounds cut
off immediately rather than lasting through
brief power interruptions or the three-second
RESET time.
The battery is dead, worn out, or disconnected. NiCad
batteries normally last about 5 years. In some very
unusual operating circumstances, the battery can be
discharged. Try allowing the engine to sit with the
power on half way for about 15 minutes to recharge
the battery. Or, remove the battery and recharge it on
a commercial charger. If this does not help, replace
with a new QSI battery.
57. I have replaced my battery a number of
times and it keeps discharging.
Are you using a QSI 7-cell 8.4 volt NiCad battery, not
the common "9 volt" alkaline battery or 6-cell, 7.2
volt NiCad battery? Alkaline batteries will eventually
discharge. NiCad 6-cell batteries can be damaged or
overheated by the QSI system; DO NOT USE
THEM.
If you are using an electronic transformer, there is
often not enough power at low throttle settings to keep
the battery charged. In neutral or RESET keep the
throttle at a high setting whenever possible. Or follow
the directions for recharging your battery in Appendix
IV.
Using "Automatic Operation" (RESET POSITION
#11) quite often with the throttle set low can discharge
your battery.
You may have a defective power supply. Send in your
QSI sound boards for repair.
58. The sound is turned up all the way but the
sounds are distorted.
The small speaker used with O-Gauge locomotives is
being overdriven by the high power output. Adjust the
volume on the top QS-2+ circuit board with a small
screw driver as shown in Appendix IV, "Adjusting the
Volume."
59. The sounds are distorted and/or scratchy
even at low volume settings.
The most likely cause is the speaker installation.
Check that no wires or other objects are touching the
cone. Make sure motor wires are not bundled together
with the speaker wires (this can cause static sounds
from the motor). Also check that there is no glue,
double sticky tape, or other adhesive touching any
part of the movable speaker cone. Examine the
speaker for any evidence of a tear. If the speaker is
damaged, replace it with a new 8 ohm 2" speaker
from QSI.
60. The engine works fine but there are no
sounds at all of any kind, except for the
"ding" when entering RESET.
The motor or chuff volume is turned down all the way
and the engines is in slave. Go to RESET Position #4
and choose "Slave Off," and go to RESET Position #6
and choose any volume except "Off."
61. The engine works fine but there are no
sounds at all of any kind, including no
RESET "ding."
The speaker is disconnected, defective or has a broken
wire. Check to be sure it is plugged into the top board
pins (see Appendix IV) or that both wires are soldered
to the two speaker terminals.
OR, the volume is turned down all the way. See
Appendix IV, "Adjusting the Volume."
