SECTION 3
Micro Tymp 2 Noise Test Procedure
The purpose to these instructions are to give a general procedure in fixing a noisy Micro
Tymp 2 handle.
1. Verify the unit by testing the unit manually with a 0.2cc, 1.0cc and 2.4cc cavity.
2. If the unit is noisy when testing manually, proceed as follows:
A.
Remove Battery cover.
B. Examine all tubing for kinks, bends, anything to restrict air flow.
C. Make sure all tubing is connected to the right place and routed per drawings.
E. Test whole system for leaks. Leaks will cause noise in the system.
3. Remove screws from front housing
4. Break fiber strips from front housing.
5. Slowly remove the front housing from the back housing. While disassembling:
A.
Check to see if the Mic, Speaker or Pressure Transducer are touching each
other or the front housing. If they are, this will cause noise in the unit.
B. Check to see if the silastic tubing from the front housing to the ballast is
pinched.
C. See if the bottom flex is routed per drawing around the L.C.D. boss.
D. See if filter tube is between the pump frame.
6. Fully open the front housing:
A.
Inspect the arrangement of the mic, speaker and pressure transducer.
B. Check the positioning of the pump in the back housing.
C. Check to see if all padding is on pump and back housing.
D. Check the positioning of the pump pads and the top cap pad.
7. Correct any problems identified and reassemble the handle.
8. Check the handle for noise. If the handle is still noisy, disassemble the unit and
check the handle in more depth. Reassemble the unit and recal. Do a noise check.
9. If the unit is still noisy, suspect that the pump assembly or motor is bad. Replace
pump assembly and reassemble. Recal the unit and check for noise.
