3.0 DT402 Battery Installation
For normal walk around (tethered) operation, the DT402 series throttles do not
need a battery. However, when you are unplugged from LocoNet, your throttle
display will go off. We recommend using a battery for DT402 operation even
though it is not required. To use your DT402/R/D as an infrared or radio throt-
tle, you must install a 9-volt battery. When you install the battery, the throttle
will report the battery voltage then show the last display screen used by the
throttle.
We recommend that you remove the battery from your throttle if it is
unplugged from the system to conserve battery life.
The battery can be stored inside the DT402/R/D by removing the battery and
putting it back in the battery compartment with the polarity reversed. See dia-
gram above for proper orientation.
DT402 throttles are shipped with the maximum power save option enabled. To
make your batteries last even longer, you may choose to turn off the display
backlight. See Section 10.0 for throttle customization options.
