Locomotive Address; Turn On The Sound - GMC Rapido F9B Operating Manual

LOCOMOTIVE ADDRESS

Your Rapido F7B/F9B comes from the factory with a decoder address of 3. We
suggest if you are using DCC control that you first test that the locomotive responds
on address 3. Once you have verified that the locomotive is responding you should
assign it a unique address (normally the road number of the unit) before going any
further. This can be done either on your programming track (recommended) or on
the main if your system supports programming on the main. Be aware however that
if you do program the locomotive on the main and you have any other locomotives
assigned to address 3 (the normal default address for new locomotives) that ALL of
them will also be changed to your new address! This is great if you want to simulate
a bunch of kids getting into the engine shop, notching the controllers, and then
running into the woods.
Note that some DCC systems get a little wonky when programming sound-equipped
locomotives on the programming track because of the high current draw. If weird
stuff happens, try programming on the main.
Rapido products are designed to operate safely between 0V and 16V. Voltages in excess
of 16V - as well as irregular waveforms, voltage spikes or short circuits - may cause severe
and sometimes irreversible damage to the product. "Train set" power packs are known to
suffer from any one of these unexpected irregularities, whereas higher-end systems have
safeguards in place to prevent this. Rapido always recommends using a power supply
system that matches the quality of the models you are running. If you're reading this,
you've obviously invested in top-of-the-line, museum-quality motive power and equipment,
so we hope you've made the same investment with your model railroad power supply too.
While many power supply systems exist, some are known to have caused problems with
model train circuitry in the past. If you have any one of the following systems, PLEASE DO
NOT USE IT until you contact us for more information: MRC RailPower 1300/1370-series,
Bachman Spectrum Magnum, Atlas 313 Universal Power Pack.

TURN ON THE SOUND

Press F8 and you will hear the F7B/F9B startup sequence followed by the sound of
it idling. You can adjust CVs to prevent the locomotive from moving until the startup
sequence has played out. Most of us at Rapido are really impatient so we turned this
feature off. Refer to a full ESU LokSound decoder manual for more information. You
can download it from the Support section of our web site.
If you press F8 when the locomotive is already moving, it will skip the startup and the
sound will just turn on. Press F8 again to turn the sound off.
