COM-DEX HEARING AID ACCESSORY - SUPPORT

The neck loop works as an on/off switch. When you connect the neck loop, the COM-DEX is turned on. If you open the neck loop, the COM-DEX is turned off.

Close the neck loop on COM-DEX. The COM-DEX will now blink in blue and red. For most phones, go to “Settings” and select the Bluetooth menu. Scan for available Bluetooth devices, and select COM-DEX XXX (last three digits in the serial number found of the back of COM-DEX) when it appears in the search list. If a password is required, use 0000.

Press the Push button on the front of COM-DEX. You can also answer the call by operating your smartphone.

If you answer the call on your smartphone, you may have to manually select the COM-DEX as a sound source. This depends on your smartphone model and its settings.

Yes, any phone with Bluetooth can use the COM-DEX. When you have connected your phone with the COM-DEX via Bluetooth, you can answer calls by pressing the Push button on the COM-DEX and end calls by pressing the push button again. You can also listen to music without the COM-DEX App.

You cannot control your hearing aid(s) with the COM-DEX alone. To do this you need to install the COM-DEX App.

When you charge the COM-DEX, you must open the neck loop. When it is fully charged the LED lights green.

Do not expose COM-DEX to extreme temperatures or high humidity, and do not immerse in liquids (it is not waterproof). If your COM-DEX gets wet or dirty, clean it with a damp cloth. Do not use chemicals.

There will be no audible alarm in the hearing aids.

You can see the battery status of the COM-DEX in the COM-DEX App (More -> Status). The LED on the COM-DEX will blink in red when 5% battery power remains. If you use the App, you will see a warning in the upper right corner of the App when 20% battery power remains. At 20% the battery warning will be yellow. When below 5% it will turn red. This also applies to Apple Watch and Android Widget.

1) Connect COM-DEX to your device
2) Chose a media player
3) Play music

This is caused by Bluetooth technology.

Therefore Widex does not recommend using COM-DEX for media that contains both sound and video, though it may work.

This is caused by the delay when starting the Bluetooth stream. A possible solution is to play music in the background as this keeps the stream open and thus avoids the start-up delay.

Calls must be answered by pressing the Push button on the COM-DEX, then the call is directly streamed to your hearing aid(s).

If you answer the call on your smartphone, you may have to manually select the COM-DEX as audio output.

The range is about 10 metres (32 ft.)

No, there is no telecoil in the COM-DEX.
