CustomShield Series Hearing Devices for Hunting
Instructions

CustomShield Series Multi-Pursuit + WingShooter Rechargeable
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 are 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 it 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: 1. Make sure your ear canal is not blocked with wax. 2. Make sure the tip is not too worn or too small. 3. 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 it 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 battery and wax guard. Make sure the battery is not dead and is inserted correctly.
Reminder: you should not have to force the battery door shut, and once closed, the battery should not be exposed.
Always take great care when opening and closing the battery door. Do not carry the device by the battery door. Never pull the door further back than is necessary when inserting or removing the battery.
Always open the battery door or remove the battery entirely from the device while you are not using your TETRA Hearing™ gear. Old batteries can corrode in devices and batteries will run down with doors closed.
Replacement Sleeves, D-Rings, and Wax Guards are available online.
