Tetra CustomShield Series Quikstart Manual

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. ll-gui es.c m

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 best performance. 1. Battery Instructions Each device uses a size 13 battery. TETRA recommends using brand-name batteries as others may vary in size. While TETRA devices are not hearing aids, they do use the same type of battery commonly used in hearing aids. Such batteries are designed to have a long shelf life, but they can go “stale” if on the shelf for a long time. Be sure to check the expiration date. Pulling off the plastic tab activates the battery. Do not pull the tab off until you need to use the battery. Check to make sure no adhesive from the plastic sticker is remaining on the battery blocking the activation holes. 2. Battery Life With daily use, the battery should last 7-10 days. With intermittent use, batteries may last for up to a month once activated. Even if not used, once the battery is activated, it has a limited life. We recommend new batteries if the device has not been used in several weeks. Low Battery Indicator- If you haven’t used your TETRA devices in a few weeks and aren’t sure how old your batteries are, don’t worry, we’ve got your back. All TETRA devices include a low battery indicator. A warning of three double beeps every eight minutes indicates that the battery needs to be replaced. If you do not change the battery, you will hear another warning of six double beeps, at which time your TETRA device will turn off. TETRA Tip: Once you remove the tab, let the battery sit for a couple minutes before inserting it into the device. This can help your battery last longer.

Because of their small size, we recommend that you insert or remove batteries on a table, desk, or some other safe place to reduce the risk of dropping the instrument or battery. STEP 1 Using your fingernail, gently pull up on the battery door tab A until the door swings open. Do not over-extend the battery door as damage will occur. STEP 2 Note: The rounded edge of the battery B is negative, and the completely flat side is positive. The flat side (+) needs to be on the door’s (+) side. With the red (+) of the battery door facing you C , hold the battery with the rounded edge positioned towards the back, gently push the battery straight in. The lower part of the battery door will flex to accept the battery. STEP 3 With the battery installed, gently close the battery door. Wait for three seconds while the device powers on. To turn the device off and to prevent battery drain when not in use, gently pull the battery door open. STEP 4 To remove the battery: With the battery red door (+) facing you, tilt the bottom of the battery towards you. This will allow the battery to move from under the front lip. Please dispose of used batteries in an environmentally friendly way. Do not place batteries in your mouth. If swallowed, contact your physician immediately or call the National Battery Hotline at 1-202-625-3333. Round edge: negative (-) Flat edge: positive (+) A B C TETRA Tip: When closing the battery door, it should go into the device VERY easily. If you must push hard or feel resistance, do not force it. The battery is likely placed incorrectly in the door. Resist the urge to force it!

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 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. D 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.

The TETRA CustomShield 60 has 3 programs settings (Normal, Boost, Magnum). When you press the program button E you will hear an audible beep(s) in your ear. 60 level products have three hunting/shooting programs: Program 1: (1 beep) Waterfowl or Range Program 2: (2 beeps) Waterfowl or Range Boost Program 3: (3 beeps) Waterfowl or Range Magnum The TETRA AlphaShield 90 has three hunting/shooting programs and a fourth program ideal for speech clarity. When you press the program button you will hear a voice prompt denoting which setting you are in. For example, if you have the TETRA CustomShield 90 Waterfowl series, the voice prompts you will hear will be as follows Program 1: (1 beep) Waterfowl or Range Program 2: (2 beeps) Waterfowl or Range Boost Program 3: (3 beeps) Waterfowl or Range Magnum Program 4: (4 beeps) ClearComm (designed for use both hunting and elsewhere where clear hearing for voices is needed) 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. 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). F E

• 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. • Do not drop the devices. • Remove your devices before using hair spray, perfumes, sunscreens or shaving lotions, as these items can clog or damage your device. • If your devices stop working, check the battery. Make sure the battery is not dead and it is inserted correctly. You should not have to force the battery door shut, and once closed, the battery should not be exposed. • Always take great caution 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 remove batteries from the devices when you are not using your TETRA hearing gear. Old batteries can corrode in the devices. For instructions and to learn more about our story and technology, please visit our website www.tetrahearing.com. ll-gui es.c m
