To terminate the communication session and power down the sensor, type [CTRL]-[C] at
anytime, regardless of the current operational mode of the ACM. This command will terminate
the communication session and power-down the sensor.
Standard ACM settings exist for use with the MMP. The system will check for these
settings at the discretion of the operator before beginning a deployment. However, the system
will not automatically program the standard settings. The ACM pass-through utility can be used
to verify and program the standard settings before a deployment.

15. From the Bench Test option on the Main Menu, select <4> ACM Communications.
16. Type ***O [ENTER] to place the ACM in open mode.
17. Type RDM [ENTER]. The system should display the following:
TX=ON, TY=ON, HX=ON, HY=ON, HZ=ON, VPATH=ON, 18
