At TETRA™, we are hunters, we are hearing scientists, and we don’t like to
read instructions. Hence, this manual is intentionally written for your
reading pleasure.
We also recommend you check out our product use and care instructions at
www.tetrahearing.com. Of course, we do want you
to read the legal disclaimers and warnings here. (Our attorney made us say
that).
Welcome to the TETRA Hearing family. We are passionate about helping you Hear
the Hunt™.
Congratulations on your purchase of TETRA CustomShield Series hearing gear.
These comfortable, day-long hearing solutions are designed specifically for
the hunter and shooter. TETRA CustomShield Series products bring harmful
sounds like gunshots and loud waterfowl calling to safe levels while enhancing
the sound environment for communication, game detection, calling, and
localization. Using TETRA’s AlphaShield Compression™ technology, all sounds
above a pre-
determined level is immediately limited. Using your TETRA device, you will
still hear the loud sound clearly, but at a safe level. Unlike conventional
plugs or muffs, low-level sounds are enhanced using our patent-pending
Specialized Target Optimization™ (STO) algorithm to maximize hearing of your
specific hunting/shooting environment.
WARNINGS:
Improper fit of this device will reduce its effectiveness. Consult the
following instructions below for proper fit.
Individuals exposed to loud occupational or recreational noise should have
annual hearing checks to monitor their hearing levels over time.
All TETRA devices must be worn and maintained in accordance with instructions.
Cleaning regularly and paying close attention to maintenance ensures the best
performance.
Charging Instructions
TETRA rechargeable devices use a Lithium-ion sealed battery. This battery is
sealed within the device and is not replaceable by the user.
Do not attempt to remove the battery.
To charge, the TETRA CustomShield should first be turned off. To be sure the
device is off, rotate the volume control of each device until the dot on the
volume wheel matches the dot on the face of the CustomShield. Place each
CustomShield device into the color-designated cradle (red to red, blue to
blue), in the charging box with the faceplate down and the contacts lined up.
You should see a red blinking light inside the device to indicate that the
device is charging (slow blink).
A full charging cycle takes approximately 6-8 hours and the ‘slow blink’ will
turn into a solid light inside each device to indicate a full charge has been
reached. Please remove the devices as soon as possible to prevent
overcharging.
Battery Life
With a full charge, your TETRA CustomShield rechargeable battery should last
for approximately 20-24 hours of use. Turning the devices off between uses
helps preserve the batteries.
Low Battery Indicator- All TETRA devices include a low battery indicator. A
voice prompt stating “low battery” indicates that the battery needs to be
recharged.
TETRA Tip: Once you place your CustomShields into the charger, you should see
a slow blinking light inside each device. If you don’t, adjust the position of
each device until the slow blinking light appears. The charging light will
blink rapidly to indicate if the batteries are already fully charged within
10-20 seconds of placing the device on the charger indicating that no charge
is needed at that time. You may also see a rapid blink indication if the
contacts aren’t lined up correctly – adjust the position to double-check. If
rapid blinking continues, the devices do not require charging at this time.
Placement in the ear
DETERMINING LEFT OR RIGHT
A blue shell indicates the device fits the left ear and a red shell indicates
the device fits the right ear.
INSERTION
Place the canal portion of the CustomShield into the ear canal and rotate the
device backward until the helix D locks into place. Be sure the device is
fully seated in the ear and is flush (as shown here).
REMOVAL
To remove the unit from your ear, pull down on your earlobe with your thumb
and forefinger. Grab the device with either the same side hand or your other
hand and simply pull out.
Note: Do not pull on the battery door at any point. This can damage the
battery door and/ or your device.
Volume/Program Selection
The TETRA CustomShield Multi-Pursuit and WingShooter devices are equipped with a program button. To change the setting, tap the button on the face of the device to change the program. The CustomShield Multi-Pursuit has up to 6 program settings, while the WingShooter has 4 program settings.
Press the program/volume button E you will hear a voice prompt denoting
which setting you are in. For example, base programming has Waterfowl, Upland,
Elk, Range, Deer, and Turkey. Base programming in the WingShooter has
Waterfowl, Waterfowl Boost, Upland, and Range/Clay.
Note: The volume level for each program is based on the hearing test you
submitted for programming. If it sounds different than you expected, we
recommend allowing your ears and brain time to adjust to it. If it continues,
please reach out to us for further instruction.
You can also fine-tune each program by adjusting the volume control F . The
volume control can be adjusted by placing a finger on the volume wheel with
slight pressure and rotating it. With your TETRA CustomShield seated in the
ear, rotating the volume wheel forward (toward your face) increases volume.
Rotating the volume wheel backward (toward the back of your head) decreases
volume. If the device whistles, the volume is too high. Rotate back slightly.
To turn off, rotate volume control backward until the two red dots line up
(right ear) or blue dots line up (left ear).
TETRA Tip: If your TETRA device is in the ear and the device whistles, then
something is not correct. Check the following:
- Make sure your ear canal is not blocked with wax.
- Make sure the tip is not too worn or too small.
- Make sure the TETRA device is fully seated in the canal.
TETRA Tip: To check tip fit, hum, or talk with the devices in place. Your voice should sound noticeably louder with a proper occluded fit.
Maintenance
EAR WAX MAINTENANCE
- Wax buildup is the number one cause of device problems. It is important to keep your device as clean as possible. Wipe daily after use with a dry cloth, carefully removing any traces of wax and debris.
- Wax guards may also need to be replaced. If your CustomShield is not working the most likely cause is a clogged wax guard. Remove the old one and replace it. Additional wax guards can be purchased at www.tetrahearing.com.
GENERAL MAINTENANCE
- Store in a cool dry place. DO NOT store in the bathroom.
- Keep your devices dry and away from extreme temperatures.
- Keep your devices away from animals and small children.
- Take care not to drop the devices.
- Remove your devices before using hair spray, perfumes, sunscreens, or shaving lotions, as these items can clog or damage your device.
- These devices are designed to use and wear the battery down prior to charging. We also recommend charging before storing for an extended period of time. Battery life is prolonged and stored on a full charge.
- If your device stops working, check the wax guard. Make sure the battery is not dead and is charged.
- Replacement Sleeves, D-Rings, and Wax Guards are available online.
