optimal performance in your layout room. See your starter set man-
ual for more information about installing UR90 and/or UR91s on
your layout.
2. For Radio operation, plug in at least one Digitrax Radio receiver
UR91 to your working LocoNet. Most layouts only need one UR91.
3. Install a 9 volt battery in your DT400/R. See Section 22 for battery
installation information.
4. Plug your DT400/R in to LocoNet and it will verify that at least one
infrared and/or radio receiver is connected to LocoNet. The throttle
will display either rA or Ir (depending on whether it finds an
infrared or radio receiver first) followed by the current LocoNet ID.
This example shows that the DT400/R has detected a radio receiver
and that the current LocoNet ID is 01. The throttle has loco address-
es 03 & 1280 selected.
5. The DT400/R will use the
LocoNet ID
of the LocoNet it was plugged
in to and will begin to operate as an IR throttle when you unplug it
from LocoNet. When you unplug from LocoNet, the tetherless indi-
cator will come on and the tetherless message will display for a few
seconds indicating whether the throttle is running as Ir (infrared) or
rA (radio). It will also display the LocoNet ID that the throttle is
logged on to.
6. When you single click or turn either throttle knob to activate it, the
DT400 will show the normal operating mode Fn display with the
tetherless indicator lit.
If an untethered DT400/R, operating as a tetherless throttle, detects no user
throttle activity for about 3 minutes it will enter power save mode. The dis-
play will show:
