8.1.1.1 Place the Tango M2 unit on the rubber feet and pull the front enclosure away from the rear
enclosure.
8.1.1.2 Remove the front enclosure keypad cable from the UI board.
8.1.2 Place the Tango M2 unit on the back side with the display facing up. Remove the four screws and
tooth washers that hold the Tango M2 assembly to the rear enclosure.
8.1.3 Place the Tango M2 on the rubber feet and pull the side of the Tango M2 board assembly with the
power button.
8.1.3.1 Slide the blue power button off of the power switch.
8.1.4 Place the Tango M2 unit on the back side. The pneumatic manifold and K-sound cable must be
disconnected before the unit can be completely removed from the rear enclosure.
8.1.4.1 Pneumatic manifold: Pull the tubing from the barbed connection on the rear enclosure.
Thread the tubing back through the I/O board so that the tubing exits straight out of the K-
DKA module.
8.1.4.2 K-sound cable: Disconnect the K-sound cable from J1 on the K-DKA board located
underneath the pump tray. J1 is the three-pin connector on the edge of the K-DKA board.
Thread the cable back through the I/O board. The connector and cable should remain
attached to the rear enclosure.
8.2 Reassembly
8.2.1 Place the rear enclosure on the back side to reinsert the unit. The pneumatic manifold, K-sound
cable, and power button must be reconnected first before the unit can be fully inserted back into
the rear enclosure.
8.2.1.1 K-sound cable: Thread the cable up through the smaller hole and back out the larger hole
in the I/O board. Reattach the K-Sound cable to J1 on the K-DKA board.
8.2.1.2 Pneumatic manifold: push the tubing up through the rectangular cutouts on the I/O and UI
boards and slide the tubing onto the barbed connector.
8.2.1.3 Power button: slide the power button onto the power switch.
8.2.1.4 Place the rear enclosure on the rubber feet and insert the unit onto the four guide pins.
Ensure that the pneumatic tubing is not crimped by the K-sound cable or by the unit itself.
The pneumatic tubing should form a loop. (See picture at the beginning of section 8.)
8.2.2 Secure the module to the rear enclosure.
8.2.2.1 Insert a screw and tooth washer into each screw location. Tighten securely.
8.2.3 Place the Tango M2 unit on the rubber feet and reattach the front enclosure keypad cable to the UI
module.
8.2.4 Place the Tango M2 display downwards on a soft surface. Insert the four screws located in the
wells on the rear enclosure. Tighten securely, ensuring that the keypad cable is not crimped.
8.2.5 Perform a Leak Rate test and a Timeout Test (as described in Section 6) to verify that the
pneumatic system is functioning correctly. If either fails, open the monitor back up and check for
damage and kinks in the pneumatic tubing.
