condition, back down on the throttle immediately.
Important: Tsunami will work best in analog mode when using a high quality, electronically regulated power pack, preferably one that supplies smooth, filtered DC power. Older rheostat style power packs and pulse power packs will result in erratic and unreliable operation and should not be used with the Tsunami sound decoder. If your power pack provides a Pulse power switch, leave it in the ‘Off’ position.
Depending on the quality of the power pack’s track voltage, some automatic sound functions such as the grade crossing whistle may require a higher sensitivity setting than needed for DCC operation to avoid continual triggering of the sound effect.
Analog Mode Options In addition to CV 12 and CV 29 discussed earlier, there are four other CVs related to analog mode operation:
Analog Function Enables CV 13, Analog Function Enable 1 CV 14, Analog Function Enable 2
These CVs allow you to force a function input to the ON state whenever Tsunami switches over to analog mode. This is most useful for turning on lighting effects when running on a DC powered layout. Sound functions may be turned on in analog mode as well but this is less useful as they will either run continuously or sound just once when the decoder is powered up
instead, use automatic sound functions discussed earlier to generate sound
To enable any of Functions F1 thru F8, refer to Table N below and circle the numbers corresponding to the function inputs you want to enable. Then add up the circled numbers and program this value into CV 13.
Table N. Analog Function Enable 1
Similarly, to enable Function F9 thru F8 or F0, refer to Table O below and circle the numbers corresponding to the function inputs you want turned on. Then add up the circled numbers and program this value into CV 14.
