+#
+# See https://github.com/merbanan/rtl_433_tests/tree/master/tests/nutek_car_remote/README.md
+# 
+# Manufacturer:
+# - Nutek
+# 
+# Supported Models:
+# - ATCD-1, APS99BT3BCF4, ATCH (FCC ID ELVATCD)
+# - AVX1BS4, AVX-1BS4 (FCC ID ELVATCC)
+# - A1BTX (FCC ID ELVATFE)
+# - 105BP (FCC ID ELVATJA)
+# 
+# Data structure:
+# 
+# Nutek Type 4 and Code Alarm Type 7 Transmitters
+# 
+# Transmitter uses a rolling code that changes between each button press.
+# The same code is continuously repeated while button is held down.
+# 
+# On some models, multiple buttons can be pressed to set multiple button flags.
+# 
+# Data layout:
+# 
+# x IIII CCCC B
+# 
+# - x: 1 bit always 1
+# - I: 16 bit ID
+# - C: 16 bit rolling code, likely encrypted using symmetric encryption
+# - B: 4 bit flags indicating button(s) pressed
