Ken Mattingly

Yes, sir. Loud and clear.

Jack Swigert (CMP)

Okay. It's perform CMCSM RCS preheat, and could you say again all after?

Ken Mattingly

Okay. I'm referring to the entry checklist, page E/1-5, steps 35 and 37.

Jack Swigert (CMP)

Okay. Perform CSM RCS preheat per entry checklist, page 1-5, steps 35 and 37.

Ken Mattingly

That's affirmative. Now back to panel 5: circuit breaker CAUTION AND WARNING, MAIN B, closed.

Jack Swigert (CMP)

CB CAUTION AND WARNING, MAIN B, closed.

Ken Mattingly

That's affirm. On panel 2: CAUTION AND WARNING POWER to 1.

Jack Swigert (CMP)

Panel 2: CAUTION AND WARNING POWER to 1.

Ken Mattingly

That was POWER to number 1, Jack.

Jack Swigert (CMP)

CAUTION AND WARNING POWER to 1.

Ken Mattingly

Okay. On panel 5: circuit breaker EPS SENSOR UNIT, DC BUS A and B, closed.

Jack Swigert (CMP)

Okay, Ken. The COMM from you is awful weak—awful weak, I—I can't—it's CB EPS SENSOR UNIT. Say again, after that.

Ken Mattingly

All right, Jack. That's CB EPS SENSOR UNIT, DC, that's Delta Charlie, BUS A and B, closed.

Jack Swigert (CMP)

Okay. CB EPS SENSOR UNIT, DC BUS A and B, close. And I'll give you the volts and amps.

Ken Mattingly

Okay, that's correct. Go ahead.

Jack Swigert (CMP)

Okay. Volts are 39.1; amps, 1.5.

Ken Mattingly

Okay. On panel 3: MAIN BUS A and B, go to RESET and leave it in the center.

Jack Swigert (CMP)

Okay, panel 3—Stand by; got to change OMNI's.

Jack Swigert (CMP)

Okay. MAIN BUS A and B, RESET, then center.

Ken Mattingly

That's affirmative. Okay, now we're at EI minus 5 plus 05. And, as far as you're concerned, Jack, the command module is using this for information only. This will be the LM doing an Earth-terminator AGS alinement; and at the time of 5 plus 05 is the time they'll be going ahead and releasing their ball. And this will be covered in the LM checklist; it'll be uplinked after this one. At EI minus 5, we perform midcourse number 7. Over.

Jack Swigert (CMP)

Okay. At EI minus 05:05, the LM is making an Earth-terminator aline; and at EI minus 05:00, we perform MCC-7.

Ken Mattingly

That's correct. At the completion of midcourse 7, the LM will maneuver to a separation attitude. And this attitude will be sent up on one of the pads that you're going to get before all the sequence starts. And it'll be flown to the LM ball angles on that pad.

Ken Mattingly

All right. At EI minus 4 plus 40, we want to perform page 1-6, step 39 of the entry checklist.

Jack Swigert (CMP)

Ken, I—I didn't get it. We had to change OMNI's again. Could you say it—the EI minus 4 dash—or 04:40, we do something.

Ken Mattingly

Okay. And at that time, you'll want to perform step 39 of page E/1-6. Over.

Jack Swigert (CMP)

Okay. Perform step 39 of entry checklist page E/1-6.

Ken Mattingly

That's correct. Okay. The next is the command module RCS activation, and that's step 4-1 of page E/1-6.

Jack Swigert (CMP)

Okay. The next is perform CSM—or CM RCS activation for step 4-1 of page E—E/1-6.

Ken Mattingly

All right, Jack. The next is at EI minus 4 plus 30. We want to verify that the LM is configured for command module RCS hotfire.

Jack Swigert (CMP)

Okay. Verify LM configure for RCS hotfire at EI minus 04:30.

Ken Mattingly

That's correct. Now to panel 5: circuit breaker G&N IMU HEATER, MAIN B, closed.

Jack Swigert (CMP)

Okay. Panel 5: CB G&N IMU HEATER, MAIN A and MAIN B, closed.

Ken Mattingly

That's negative, Jack. That's MAIN B only.

Ken Mattingly

I'm sorry; I lost you that time. Say it again.

Jack Swigert (CMP)

Okay. Let's repeat it. Stand by. Cut out. We've really got a strange attitude, so this is why we are having the COMM problem. Panel 5: CB G&N IMU HEATER, MAIN B, closed.

Ken Mattingly

That's affirmative. On panel 1: ROTATION CONTROL POWER, NORMAL. That's two of them, to AC/DC.

Jack Swigert (CMP)

Okay, panel 1: RHC, NORMAL, two to AC/DC, two controllers.

Ken Mattingly

That's correct. On panel 7: SCS, LOGIC POWER 2/3, ON.

Jack Swigert (CMP)

SCS, LOGIC POWER 2/3, ON, panel 7.

Ken Mattingly

That's affirm. Back to panel 2: RCS COMMAND, ON.

Jack Swigert (CMP)

Panel 2: RCS COMMAND, ON.

Ken Mattingly

That's correct. Now the command module RCS check per step 4 of page E/2-1.

Jack Swigert (CMP)

Okay. Perform the command module RCS check per step 4, page 2-1.

Ken Mattingly

That's correct. Okay, at this point, we want to lock the rotation hand controllers.

Jack Swigert (CMP)

Okay. After that, lock both rotation hand controllers.

Ken Mattingly

That's affirm. On panel 8: SEQUENTIAL, PYRO ARM, two to ARM.

Jack Swigert (CMP)

Okay. Panel 8: set PYRO ARM, two, to ARM. Do I get a MSFN GO for that?
