Tactical Sound Control (TSC):
This product includes TSC - Tactical Sound Control. TSC is a microphone technology
that allows the user to hear the world around them, but always at a safe listening level.
When ambient noise breaches a safe listening level, the microphone technology
immediately responds and attenuates to a safe level.
TSC automatically turns on when the product turns on. Adjusting the TSC volume is easy,
simply press the TSC Volume Up and Down Button.
Charging
Please charge Geronimo with the included Micro USB charing cable. When plugged
in, the Red Light indicates the product is charging, the blue light indicates the product

Adjusting the Fit
Geronimo comes with 4 sets of TRILOGYTM foam eartips (XS,S,M,L) and 3 sets of
silicone eartips (S,M,L). The TRILOGYTM foam eartips are designed for superior
comfort, superior noise blocking and superior sound quality. Choose the size that fits
most snugly in your ear canal. Remember, the snugger the fit, the better the noise
blocking. The silicone eartips are intended for use when NOT in noisy situations.
ISOtunes® TRILOGYTM foam eartips have a threaded core and the sound port on the
earbud is also threaded.
1. Twist the foam eartip counterclockwise to remove and clockwise to place on a new
foam eartip.
