First WOD segment is now loaded to the nonvolatile memory of the radio — Listen for BEEP. (9) Channel selector switch — Set to 19. (10)   Frequency selector switches — Enter sec- ond WOD segment. (11)    TONE switch — Press. (12)   The remaining four WODs can be loaded in a similar fashion by dialing the next lower preset channel, selecting the next WOD segment. After entering last seg- ment, listen for a double (3125 Hz) beep. (13)   Channel selector switch — Set to 14. (14)   Frequency selector switches — Enter date code. (15)   TONE  switch  —  Press.  At  this  time,  one complete  WOD  with  its  corresponding  date  code  has been entered to the nonvolatile memory. (16)   Additional WODs can be loaded by repeat- ing steps (5) through (15). Once WODs have been en- tered, today’s operational date must then be entered. (17)   Channel selector switch — Set to 1. (18)   Frequency  selector  switches  —  Enter  op- erational date. (19)   TONE switch — Press. b.  Operate/Verify Modes. (1) Operate Mode. (a) Frequency   mode   selector   switch   — PRESET.
