fast time based on the last synchronized system fast time when the DT400/R
was connected to LocoNet. If the fast time is edited by another throttle con-
nected to LocoNet, the DT400/R will not see this change until it is plugged
into LocoNet at which time its display will be updated.
23.2.1 Control Lock
While the DT400/R is being used tetherless, there are occasions when you may
want to disable the throttle’s controls to prevent accidental commands being
sent to the railroad. For example, your train is in a siding waiting for another
train to pass. You put your throttle in your pocket and go take a break. By lock-
ing the throttle controls, you will not be able to accidentally start your train if
you bump your throttle knob or press the Y + Key
.
To lock the controls on your DT400
1. Press both the Y +
and the N -
Keys at the same time.
When you are locking the keyboard be sure to press both the Y+ &
N- Keys AT THE SAME TIME to avoid sending a speed command
to the active loco.
2. The throttle will display “Lock=+&-” in the display and none of the
controls will function until you unlock them.
To un-lock the controls with “Lock =+&-” on the display:
1. Press both the Y +
and the N -
Keys at the same time
again. This will return the throttle to normal operation.
2. Plugging the throttle into LocoNet will also unlock the throttle.
24.0 DT400 Battery
24.1 Battery Installation
For normal tethered operation, the DT400 does not need a battery. If you want
to use your DT400/R as an infrared or radio throttle, you must install a 9 volt
battery. When you install the battery, the throttle will report the battery voltage
and then display Idle. Once you plug in to LocoNet, DT400s will begin operat-
ing infrared and DT400Rs will begin operating as radio throttles.
We recommend that you remove the battery from throttle if it is unplugged
from the system to conserve battery life.
