TM  1-1520-240-10 3-2-8            (2) Channel selector switch — Set to 20. (3) Frequency  mode  selector  switch  —  PRE- SET. (4) Frequency  mode  selector  switch  —  Set 220.025 MHz. (5) PRESET switch — Press. Radio is now pro- grammed to accept MWOD. (6) Frequency mode selector switch — MANU- AL. (7) Frequency selector switches — Enter first WOD segment. (8) TONE switch — Press. 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. (b) Channel selector switch — Set to 20. (c) Frequency  selector  switches  —  Enter 220.000 MHz. (d) PRESET switch — Press. Radio set is now programmed to operate in either normal mode or anti-jam mode. (2) Verify Mode. NOTE This verification test only checks for presence of a WOD with the corresponding date code. It does not check for the authenticity of the WOD segments entered. (a) Channel selector switch — Set to 20. (b) Frequency   mode   selector   switch   — MANUAL. (c) Frequency  selector  switches  —  Enter date code to be verified. NOTE If a single beep is not present for a particular date code and the anti-jam mode is entered using that date, a constant warning tone will be  heard  signifying  that  the  anti-jam  mode initialization cannot be properly completed. (d) Channel  selector  switch  —  Set  to  19, then back to 20. A single beep will be heard if WOD with the date code in step (c) is present. c.  Erase Mode. (1) Channel selector switch — Set to 20. (2) Frequency   mode   selector   switch   — PRESET. (3) Frequency  selector  switches  —  Enter 220.050 MHz. (4) PRESET switch — Press. (5) Frequency   mode   selector   switch   — MANUAL. (6) TONE switch — Press. All MWODs are now erased. d.  Training Frequency Load. (1) Channel selector switch — Set to 20. (2) Frequency   mode   selector   switch   — PRESET. (3) Frequency  selector  switches  —  Enter 220.075 MHz (4) PRESET switch — Press. (5) Frequency   mode   selector   switch   — MANUAL. (6) Frequency  selector  switches  —  Enter desired training frequency. (7) TONE switch — Press. A single beep will be heard. (8) The next frequency is loaded by enter- ing  the  next  lower  preset  channel,  selecting  the  next training frequency, and pressing the TONE switch. Up to 16 training frequencies may be entered. Following this procedure.
