Recalling Locos
To call up previous locos stored in the memory, press
RECALL
. You can recall up to 25 locos.
Saving Locos
Recall back the five locos you wish to use in your next session, making sure all functions are off and the
throttle is set to zero. To save the last five locos unplug the hand unit before turning off the power, SVdA
will be displayed briefly confirming the save. After you have reset your five locos, plug the Walkaround
back into the unit and then disconnect the power. You will then be ready for your next operating session
and the five locos will be saved in RECALL
Tip
Use the
DELETE
button to remove any unused locos from the stack before saving your favorite five.
Note
Although the Cab can recall up to 25 locos for operation, if you “power off” the Cab from the base unit,
it will only retain the last five locos previously saved.
Deleting Locos
The Cab can store up to 25 locos. If you select a new loco when the Cab is full, the new loco will replace
the current loco. The current loco will be lost. To prevent this, we recommend you recall unused locos and
delete them by pressing and holding
DEL
for 2 seconds.
Emergency Stopping
For emergency stopping of the current loco, press
STOP.
Pressing and holding
STOP
for 2 seconds will
stop the Main Track output. The 2 lights on the base unit will blink. To restore the Main Track output, press
and hold
STOP
for 2 seconds again.
Speed Steps
Speed steps are incremental steps the loco takes to go from 0 to top speed. There are three speed steps:
14, 28 and 128. The higher the speed steps setting, the higher the number of different speeds on which the
loco can operate. When you enter a new loco address (an address that has not been stored in the Cab’s
memory) Prodigy Express will set 28 speed steps as the default setting for that address. In order to operate
your loco properly, you may need to change the speed steps setting to match the decoder’s speed steps.
To select other speed steps settings, press
SPD STEP
repeatedly until you see your desired speed steps
setting. Then press
ENTER
. The selected speed steps setting will apply only to that address.
Note
Use of the speed step button will not alter the speed step originally programmed into the decoder. It
only matches the throttle to the decoder.
Overload and Short Circuit
The base unit is rated at 2 amps. It is up to you to note how many locos and accessories can be run on the
layout at the same time without triggering the circuit protector. If there is an overload or short circuit, the
base unit will stop Main Track output for 2 seconds then resume. Please remove the overload or short cir-
cuit for proper operation. When operating larger layouts with numerous locos and accessories being oper-
ated at the same time you may need a DCC power booster.
