Batteries can be stored inside the DT400/R by removing the battery and
putting it back in the battery compartment with the polarity reversed.
24.2 Low Power Indicator
While it is running as a tetherless throttle, the DT400/R automatically checks
the power available to the throttle each time a battery is inserted and each time
it is plugged into or unplugged from LocoNet. The power from the battery or
from LocoNet will be displayed in the text area of the throttle briefly each time
the throttle is plugged in or is unplugged from LocoNet.
When you plug in to LocoNet the number displayed will be the power provided
by LocoNet. This value will be between 9 & 15 volts. Other characters will
also be displayed in the LCD depending on which locos are selected and their
speed and direction.
When you insert a battery or unplug
from LocoNet, the value displayed
will be the battery power. When this
number is less than 6.2 V you may
want to consider changing the battery.
The DT400/R will still continue to
operate reliably for an extended period of time depending on the type battery is
in use. 9 volt alkaline batteries are nearing the end of their life at 6.8 volts, but
7.2 volt NiCad rechargeable batteries may still have lots of life remaining.
Experience will determine how long your DT400/R will operate with the bat-
teries you are using.
