(A) Function Key Usage:

F0-     Lights  - Steam has generator dynamo
F1-    Bell            [CV157 selects bell type]
F2-     Horn/Whistel          [CV150 selects Horn/Whistle type]
F3-     Coupler crash        [Autocoupler/brake set by  CV151 max spd]
F4-     Air feature disable- F4  OFF enables pop-off,drier and starts compressor/airpump
F5-     Diesel= Dynamic brake Fans,  Steam= Waterpump turbine
F6-     Diesel=Notch UP - Steam=Blowdown ; iff CV155 is not 0
F7-     Crossing Gate Airhorn or; Diesel=Notch DOWN/Steam=Wheelslip, ;iff CV155 is not 0
F8-     Mute control,     [F8 ON is muted.]
F9-     Brake squeal
F10-     Crossing gate Airhorn/Whistle sequence
F11-     Steam=Greaser
F12-     Steam=Safety Blowoff

(C) General Notes

The SDXH166 decoder is factory programmed with 8 locomotive scheme examples to provide a number of locomotive choices
without requiring user downloading.
CV60 0 to 7 selects: 0= GP38-2, 1=GE Evolution, 2=SD70, 3=GP10, 4=RS-1, 5=C420, 6=Steam Challenger-3985, 7= K27-464
Downloads are a mixture of 8 bit, 12bit and 16 bit wave files.

The Digitrax Sound Depot has an assortment of other sound projects downloadable with a Digitrax PR-3 that have more
detailed individual schemes. The SDXH166 series allow downloading of 8,12 and 16 bit wave files and up to 4 voices,if defined
in the SDF project definitions.

For CV155=01 ["Semi_automatic Notching"] when CV60=0 to 5 (Diesel),  the Prime mover lowest Notch setting is set by
 the throttle speed setting. F6 (ON) can increase the Notch and F7 (ON) will decrease the Prime mover
to the minimum notch set by current throttle setting.

For CV150=0 the scheme default horn/whistle is different for each scheme, for a total of up to 10 horns and 3 whistles.
Whistles are typically CV150:6 and 7 etc..
For CV157=0 the scheme default bell is different for each scheme, for a total of up to 8 bells.

Cam triggered exhaust sounds are only configured for 8 or 16 bit wav file downloads.
