Self-assistance for the Labex Harmony Electrolarynx

The Labex Harmony electrolarynx comes ready to use. It is a very easy to use and reliable device with an integrated high-capacity Li-Ion battery. The intelligent charge hardware negotiates with the connected port to execute the fastest and secure charge process possible.

In this short video, you can see the normal course of the initial startup for Labex Harmony electrolarynx.
At the start-up time, a short and quiet sound will be emitted to help you feel, and ensure that the device is working properly.

When turning the On/Off switch to the On position the unit performs a battery check and shows the result by the LED indicator on the Control Panel above both talk buttons.

Depending on the remaining capacity of the integrated battery the color of the LED is as follows:

  • If the battery charge is more than 50% of the capacity the LED glows in green.
  • In case the remaining capacity is between 25% and 50% the LED glows in yellow.
  • In case the remaining capacity is between 10% and 25% the LED glows in red.
  • In case the remaining capacity is less than 10% the LED lights up in red, but the sound is disabled to force charging the device.

The battery capacity allows more than 30 hours of speech time, which typically is enough for 2 weeks of average speaking.
All options and adjustments for the Harmony electrolarynx you can find on the product page on the labextrade.com website.
