47. The engine is stuck in Lock-Out and the
engine sounds stutter or stop when power is
interrupted to change direction. The battery is dead, worn out, or disconnected.
QS-2+ needs the battery back-up to activate Lock-out.
If there is a NiCad battery connected to QS-2+, try
recharging it by leaving your engine powered up at
half throttle or more for fifteen minutes. Or remove
the battery and recharge it on a commercial charger. If
the battery is dead, a common 9v battery can be used
to get your engine operating again but it will
eventually wear down since it cannot be recharged.
Replacement NiCad 7-cell, 8.4 volt batteries are
available from QSI and some electronics stores.
Troubles With Sound
48. When operating the horn or whistle, the
sound seems to turn on very slowly or not at
all, the horn or whistle may sound distorted at
low throttle settings or there is a dead zone
when I release the horn button. The battery is dead, worn out, or disconnected. NiCad
batteries normally last about 5 years. If the engine is
consistently operated at high sound volume and low
throttle settings, 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 enough to
get the engine going. If this works, lock the engine in
neutral, turn the power up to half throttle and let it
change for 24 hours. Or remove the battery and
recharge it on a commercial charger. If this does not
help, replace with a QSI NiCad 7 cell 8.4 volt battery.
49. I cannot get the flange sound effects to
turn on with the horn button. Your horn signal may be weak. In order to operate the
flange sound reliably, you need a strong horn signal.
ZW's usually have a poor horn signal if you hold the
button down all the way. Try pressing the horn button
down only half way for short periods; it should
operate the flange sound consistently.
OR the Flange effect has not been enabled. Go to
RESET position # 46 and select "Flanges Arm
Enabled" or "Flanges Always".
OR you may have selected "Flanges Arm Enabled"
and are not arming the Flange effect with the Bell
Button. See RESET feature #46 for more details.
