Note: Consistent activation of the wheel flange squealing is determined by the condition of
your transformer’s whistle button rectifier disc. Older rectifier discs may need to be replaced
in order to play squealing sounds.
SELF-RECHARGING BATTERY BACKUP
ProtoSounds® state-of-the-art design includes a self-recharging battery
backup system for improved performance at any speed. The battery ensures
that power to the sound system will remain on during directional changes,
setting RESET options or when traveling over dirty track and switches. The
self-recharging battery backup system is automatically turned on or off
whenever track power is turned on or off. There are no switches needed to
enjoy the benefits of the automatic battery backup system.
ProtoSounds® contains a warning alarm if the battery backup system fails
to automatically disengage when track power is turned off. Should the
backup system fail, you will hear a repeating whistle blast indicating this
has occurred. Should this happen, unplug the battery from the
ProtoSound® module (to prevent the battery from being run down) and
contact MTH for instructions on returning the tender for repair.
REPLACING THE PROTOSOUNDS® BATTERY
The ProtoSound® battery (located in the tender body), is a special NiCad
7-cell, 8.4v battery - NOT the 6-cell, 7.2v battery found in most
convenience stores. The 6-cell NiCad is NOT recommended for use with
ProtoSound® applications. The battery is continually charged from the
track when power is applied and should last for up to five years. In
addition, the NiCad battery is a dry battery and should not leak or cause any
damage to your locomotive during its lifetime.
If you notice that the sounds seem distorted or garbled at low voltages or
become silent when power from the transformer is shut off, the battery may
be going bad. Before replacing the battery, you should put the engine in
NEUTRAL and leave the transformer throttle set at about 12 volts for 15
minutes. This should temporarily recharge the battery. If the garbled or
distorted sounds are reduced, then your battery charge has worn down. You
can give your battery a full charge by leaving the engine ON in the
NEUTRAL position for 18 hours. (Make sure the smoke unit switch is in
the OFF position to prevent harm to the smoke unit wicking).
