ExSilent Qgo Manual 

1 Qgo module 2 Battery 3 Qgo soft tip package 4 Carrying box 5 Qgo Quick start guide 2 Placing the battery While using a new battery: first remove the sticker from the (+) positive side. • Insert the battery between the battery contacts of the module: the flat side (+) positive side of the battery should be placed on the large battery contact. 3 Inserting Qgo in the soft tip Correct placement of the module in the soft tip is essential for a good sound and a proper performance of Qgo. Therefore always check the following points to ensure that the module has been inserted in the soft tip correctly: 1 The module is orientated correctly if inserted as in the image: The flat side with the serial number and the battery facing towards the pull cord, the brand name (logo) facing away from the removal handle. 2 The top of the flat side of the module should fall just under the last ridge of the removal handle. 3 An imaginary line running between the round cap and the push button should be parallel to the removal handle. 4 The edge of the soft tip should fit over the groove around the module. When fit together, a dark contact stripe will be visible around the module. If one or more of these points are not carried out correctly, the sound quality or the fit in the ear may not be optimal or the device might whistle (feedback). If this happens, hold the soft tip and turn and/or push the module into the correct position or remove the module and reinsert it in the soft tip. 4 Placing Qgo in the ear Insert the device into the ear by pressing on the flat side of the device (with the push button) in a small circular motion. Now gently ‘massage’ the device deeper into the ear. If the mouth is opened wide, insertion will be easier. The use of insertion crème/ cosmetic skincare/gel considerably eases the insertion. Make sure your hands are clean while inserting the Qgo. Make-up, crème, body oil, gel, hairspray and likewise products can dirty up the module and can, for example, contribute to the clogging of the microphone opening.

Hold the removal handle firmly and pull it – always slowly – out of the ear. 5 Adjusting the volume The push button is used to select the volume setting you prefer. By touching the push button briefly, one of four pre-set volume levels can be selected. These levels are softer, as well as louder. One can identify the volume level by the number of beeps that will sound after touching the push button. After insertion of the battery, the device is set by default to the initial volume. Just a short touch to the push button will produce two beeps, indicating that the next volume level is activated. After another short touch to the push button, three beeps will be audible indicating that volume level three has been activated. Another touch to the push button will activate volume level four. While you are in level four, after pressing the push button one beep becomes audible and the device sets back to the initial volume level. Cleaning The building up of ear wax differs from one person to another. Therefore, from time to time it cannot be avoided that the sound outlet of the soft tip will be clogged with ear wax. In case you observe that the sound outlet of the soft tip has been clogged, you may clean the soft tip or replace it. Module: • Clean regularly with a soft and dry tissue. Soft tip: • Clean regularly with a soft and dry tissue. N.b.: Never use aggressive cleaning products, abrasives or solvents! This can cause irrevocable damage to the soft tip or the module. Storage At night: We recommend that you remove both soft tip and battery from your Qgo during the night and store it in a secure place outside its box. In this way, you increase the operational life of the battery and also allow for the evaporation of moisture possibly present in the device. Short term storage: You may use the carrying box, when you want to remove the device from the ear temporarily. Long term storage: When you don’t use your Qgo over a longer period of time, clean the module and soft tip before storing

remove battery and soft tip from the device. Trouble shooting If your Qgo makes a whistling sound regularly, make sure that: 1 the correct size of soft tip has been used 2 the module has been inserted properly in the soft tip and 3 Qgo has been inserted properly and far enough in the ear If you wear your soft tips too long, the material could deteriorate and loose its seal. In that case replace the soft tip with a new one. N.b.: It is normal that the Qgo makes a whistling sound if you place it in the ear. If you can not hear any sound from the Qgo, it is possible that: 1 the battery is dead. Battery life depends very much on the wearing time. If you wear the Qgo app.16 hours a day, you should at least have 4 days of battery life. Bare in mind that a cell battery always draws power after removing the sticker, even when not used in a device! 2 the sound opening of the soft tip is blocked with ear wax. If this is the case clean the soft tip (see chapter ‘Maintenance and use - Cleaning’) or replace it. If the removal handle protrudes after the insertion of the device and becomes visible, it can be easily custom-cut with a side cutter or a pair of scissors. Important • Do not adjust the volume level too high. • Do not use the Qgo in very loud environments. • Adjust the volume with the push button just high enough for good speech understanding • Ringing ears might be a sign that the volume level is too high. Adjust the level by using the push button. • Before inserting Qgo in the ear, have your ears checked. If there is excessive cerumen in your ear canal, have it cleaned first. Do not do this yourself. Always turn to an ENT doctor, a physician or an audiologist for these procedure. • Never use the Qgo module without soft tip. The soft tip is an essential part of Qgo. Without the soft tip it will be difficult or even impossible to remove the module from the ear. In that case medical care is inevitable. Also, without the soft tip, Qgo will not be able to function properly and this could cause irreversible damage the module. • Never use damaged or dirtied soft tips. This can negatively affect the hearing performance or result in an uncomfortable fit, which in turn could lead to infections of the ear. • Replace the soft tip of your device regularly, even

• If you suffer from persistent pain, continuous irritation or itching, stop wearing Qgo and seek medical advise. Always have your ears and your hearing checked regularly. • Care should be taken in using make-up, crème, body oil, gel, hairspray and similar products, while you are wearing or inserting the Qgo. They can affect your device in many ways such as, contribute to the clogging of the microphone opening. • It can be a choking hazard to small children. • Used batteries and old Qgo devices should be collected and disposed as small chemical waste. Do not use the Qgo in the following cases: • Exostoses (bulging bone growth) in the ear canal. • Heavy ear wax secretion. The device should not be: • dropped. • exposed to moisture or water. • immersed in water. • used while swimming, taking shower, bathing or in the sauna. • exposed to extreme high temperatures, such as when using a hair dryer. • worn in mines or other environments where explosion risk is high. • exposed to X-ray radiation or strong magnetic fields, such as during medical investigation. • worn in the places where hairspray (hairdresser) or solvents (such as dye) are used.
