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
is charged.
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.

2. Carefully compress the foam eartip on the stem/sound port.
3. Insert the foam/eartip into your ear as deeply as is comfortable and hold for 5
seconds while the foam expands.
4. Repeat with second eartip.
Hint: To open your ear canal wider, lift the top of your ear up and away from your head,
as shown in the diagram.
Noise Attenuation
APPROVAL: ISOtunes® Geronimo is tested and approved in accordance with ANSI
S3.19- 1974 Specifications.
NRR Testing
The level of noise entering a person’s ear, when ISOtunes® XTRA 2.0headphones are
worn as directed, is closely approximated by the difference between the A-weighted
environmental noise level and the Noise Reduction Rating (NRR). Improper fit of this
device will reduce its effectiveness in attenuating noise. Consult the enclosed
instructions for proper fitting.
Example:
1. The surrounding noise level measured at the ear is 100 dB.
2. The NRR of ISOtunes® XTRA 2.0is 27 dB.
3. The noise level entering the ear is approximately equal to 73 dB.
Please note that the NRR is based on the attenuation of continuous noise and may not
be an accurate indicator of the protection attainable against impulsive noise, such as
gunfire.
