Dry & Store Global II

$114.95

Global II is an electrical appliance for nightly use at home to store and care for all types of hearing instruments, including hearing aids, cochlear implant hardware, noise/tinnitus maskers, and in-ear monitors. It combines the three essential elements needed for effective drying: heat, moving air, and a desiccant that drives the relative humidity really low, and captures the moisture that is released. During the first ninety seconds of the Dry & Store Global II cycle, a UV-C lamp sanitizes the hearing instruments, after which conditioning continues for 8 hours. The unit then automatically shuts off, continuing to store the instruments until they are needed.

The temperature inside the Global II may be too high for some RECHARGEABLE devices. If you have rechargeable devices, we recommend DryBoost UV. Learn more about DryBoost UV.

Description

Physical Characteristics

  • Weight: 1 lb., 3 oz. (.5 kg)
  • Unit size: 7.2” wide x 4.9” deep x 3.3” high (18.3 cm x 12.4 cm x 8.4 cm)
  • Drying compartment tray: 3.9” x 3.8” x 1” (9.9 cm x 9.7 cm x 2.5 cm)
  • Operating Temperature: 105–108°F   If hearing devices are removed shortly after the cycle has end, the devices will feel quite warm to the touch. This is normal.

Positive-latching hinged lid with a drying compartment that will accommodate most types of hearing aids, including many body worn aids. Dry & Store Global II can also be used with cochlear implant microphones, headpieces, and speech processors (both ear-level and body-worn).

Electrical Characteristics
After pressing the ON button, Dry & Store Global II will run for 8 hours before automatically turning off. However, if the lid is opened before the 8 hour cycle is complete, the unit turns off and the electronics timer resets itself.

During the 8-hour cycle, the operating temperature inside Global II is ~98°F (37°C) to 104°F (40°C). If you have rechargeable hearing aids, consider DryBoost UV instead. It has a lower temperature that is suitable for rechargeables.

  • Input Power: 100-240 volts AC, 50/60 Hz, 1.0A maximum.
  • Output: 24 VDC at 15W maximum.

The default AC Adapter has a US/North America plug. Global, Global II and Zephyr power supplies are interchangeable. All power supplies are CE marked. They are certified to ETL, UL, and CSA standards. Will also work with an inverter for 12V service. Your Dry & Store Global II can be used anywhere in the world–no voltage converter is necessary. All that’s needed is the appropriate plug adapter. A worldwide configuration is also available that contains a power supply with the following interchangeable blades: AUS, EU, STD, UK.

Desiccant
Global II ships with the custom Dry-Brik® II desiccant. The Dry-Brik contains an aggressive sorbent (mol sieve) packaged in an attractive, molded, disposable container. Each Dry-Brik has a shelf-life of at least eighteen months, unopened. Once the foil label is removed, the Dry-Brik II lasts two (2) months. Replacement desiccants are inexpensive and are available from Dry & Store distributors and directly from Ear Technology Corporation. The desiccant also absorbs odors as it dries.

UV-C Properties
The Global II lamp produces UV-C wavelengths of light. During its one-and-a-half minute cycle, just 90 seconds, the lamp will generate enough UV-C energy to yield a 99.99% reduction of bacteria, specifically Staphylococcus Aureus.

Battery Removal
Batteries do not have to be removed from hearing aids before Dry & Store use. We do recommend the battery doors be open.

Frequently Asked Questions

Tweak Enhance has four listening modes: Conversation, Restaurant, Traffic, and Outdoors. The noise modes suppress background noise. The rocker switch is used to switch between listening modes.

Press and hold the lower portion of the rocker switch for two seconds then release. Do the same to switch to the other programs.

Enhance-switching listening modes

Once setup is complete, every time you turn on your Tweak Enhance, it will revert to the last program and volume setting you used.

Tweak Enhance includes one set of accessories: a pack of the most commonly used sound tubes (size 2B, right and left) and domes/tips. However, other sizes are available.

It is important for the sound tube and tip to fit properly in your ear. If you need a different size tip or tube, call 1-888-815-3240 for assistance. You can also order online:  https://www.eartech.com/product/simply-tweak-enhance-and-refocus-replacement-tips-and-tubes/

The sound tube delivers amplified sound into your ear. Sound tubes that shipped with your Tweak Enhance and sleeve tips should be tried first. The sound tubes are size 2B. 

If you get feedback or whistling, change to a more closed tip. Also try decreasing the volume.

It is important for the sound tube and tip to fit properly in your ear. If you need a different size tip or tube, or if you continue to have a problem, call 1-888-815-3240 or assistance.

Make sure the tip/dome is not clogged.

Fully charge the battery.

Make sure the hearing aid case and sound tube are clean and dry. (Refer to page 51 in the Enhance user manual.)

Make sure the hearing aid case is positioned correctly behind the ear, and that the tip is positioned properly in the ear canal.

Make sure the volume is turned up, by tapping the upper portion of the rocker switch.

Excessive ear was can prevent sound from entering the ear. Contact your physician.

Changes in your hearing can affect how you hear with Tweak Enhance. Contact a hearing healthcare professional if you suspect any change in your hearing condition.

Tweak Enhance may need to be reset. See page 44 of the user manual for instructions. Follow prompts on-screen to set up the hearing aid.

To turn ON, press and hold the upper portion of the rocker switch until you hear a beep (approx. 3 seconds) then release. While you are holding the rocker switch, it will turn green. The green light will turn off once the hearing aid is ON.

To turn OFF, again press and hold the upper portion of the rocker switch until you hear a beep (approx. 3 seconds) then release. While you are holding the rocker switch, it will turn blue. The blue light will turn off once the hearing aid is OFF.

Also, the hearing aids will automatically power OFF once they are seated properly in the charging base. However, after removing the hearing aids from the base it will be necessary to power them ON using the rocker switch.

Tweak Enhance is powered by a lithium polymer battery that is rechargeable. It’s best to charge your hearing aid completely prior to each use.

When not in use, turn off the hearing aid to prevent unnecessary battery drain or leave it in the charging base. See page 46 of user manual for instructions on turning power on/off.

Enhance hearing aids have a non-removable lithium-polymer battery. It is not user-changeable. Call Tweak Support for assistance – 1-888-815-3240.

Time to fully charge:
Approximately 3 hours

Battery life of full charge:
Approximately 20 hours
Keep in mind some functions of the hearing aid (volume level, noise compression, etc.) require more energy than others. You may find the battery needs recharging sooner than 20 hours.

No. Moisture is the number one enemy of hearing instruments. It can damage the microphone and other components, resulting in costly repairs. Don’t wear the device while taking a bath, shower, spa treatment or while swimming. (See page 55 of the user manual for a list of tips.)

We recommend the daily use of a DryBoost UV drying appliance. These dryers are available on the Accessories page of the eartech site.

The Tweak device has a best-in-class feedback management system. However, when your hand is near the device, you may hear a whistling noise, which is called “feedback”. This may be caused by amplified sound bouncing off your hand back into the instrument. The noise usually quits when you take your hand away.

If the whistling doesn’t stop once you’ve moved your hand away, ensure that the amplifier case is positioned properly behind the ear, and that the tip is positioned properly in the ear canal.

Try adjusting the volume. Tap the lower portion of the rocker switch to decrease volume.

Make sure the dome/tip and sound tube are not clogged with wax or other debris. (Refer to page 52 of the user manual.)

Instead of the sleeve tip, consider using one of the more closed domes.

Try adjusting the equalizer via the Enhance app – decrease the higher frequencies.

If the above fails to reduce feedback, contact Tweak Support at 1-888-815-3240.

Yes, Tweak Enhance has a 45-day trial period. After using Enhance for 45 days, you can return it for a full refund.
