ue to the inevitable derailments, static, and the nature of electricity, it is possible that your
Command reverse unit could someday lose its setup program.
The symptoms of this condition would be unresponsiveness in Command mode. This can be easily
remedied by "reprogramming" your Command reverse unit using the following steps.
STEP 1: Move switch on locomotive from RUN to PROGRAM.
STEP 2: Plug-in Command Base.
STEP 3: Place locomotive on track, then turn on power to track.
STEP 4: Press "ENG" then input locomotive's ID#. Press "SET".
STEP 5: Press "ENG," then the ID#, "AUX1", then press the number 74.
STEP 6: Turn off power to track and wait ten seconds.
STEP 7: Remove locomotive from track, move switch from PROGRAM to RUN.
STEP 8: Place locomotive back on track, turn power on to track.
STEP 9: Press "ENG" and ID#, then operate as normal.

Maintaining your locomotive's handrail antenna

Y
our locomotive handrails are more than just model grab irons—they're the Command control
unit's antenna for receiving Command Base digital communications. Please handle the loco-
motive carefully to avoid handrail damage. To ensure optimum reception, both handrails are insu-
lated from the die-cast shell. If your locomotive experiences difficulty receiving Base communications,
check the handrail ends in the cab and pilot for the presence of insulating material. Ensure that each
insulator is present and enjoys a proper fit. Finally, prevent the handrails from touching any part of
the die-cast locomotive cab.
