Main materials and tools
1. Main materials
•Double-sided tape
Select a tape suitable for your usage environment.
Recommendation: 4910 (made by 3M)
If you are using the acoustic tube system, cut a piece of tape
approximately 50cm (20") longer than the total length of the
tubes.
If you are using the optional microphone, cut a piece of tape
approximately 10cm (4") in length.
•Connection cable
Use a 2-conductor shielded cable for the microphone, and an
18AWG cable for the speaker. The cables should be long enough
to extend from the microphone and speaker to the main unit.
•Cleaning fluid
Fluid for cleaning the surface before adhesion (a fluid that will
not affect the adhesive power of the double-sided tape).
2. Special tools
• Metal saw
Use for cutting the acoustic tube.
• File
Use to smooth the cut surfaces of the acoustic tube.
