Monorean Pro Guide
The advanced version of the Monorean earpieces.
The Control Box
The sophisticated control box ensures that every last detail communicated through the invisible earpiece is transmitted perfectly, guaranteeing success on any exam.
Bluetooth
The control box is Bluetooth® 5.0 certified, allowing it to be connected to a smartphone, MP3 player, Walkie-Talkie, or any other Bluetooth device. Your Bluetooth device and the control box can be separated up to 10 meters.
NOTE: During the pairing, if a password is requested, enter 0000
For safety, the control box has a percentage of power on reserve that is exclusively dedicated to the Bluetooth link, so that if the device runs out of battery, it can maintains the connection— avoiding an adverse situation if the cell phone unexpectedly switches to “speaker” mode when the Bluetooth connection is lost.
IMPORTANT: Once it has been paired with your cell phone via Bluetooth, no other phone will be able to find the control box on its list of available Bluetooth devices within range.
Power supply and battery
The electronic device or control unit is powered by an internal rechargeable lithium polymer battery. The Monorean Pro control unit can be charged using the provided UBS cable. Remember that you can connect the USB cable to either a USB port on your computer or a USB dock connected to a power source such as a wall socket.
The battery indicator ( 
) will be red indicating: charging. It’ll be fully charged once the indicator turns green.
The battery can last for 6 hours with a continuous connection.
Battery details
Monorean Pro automatically manages and optimizes the battery life. The Monorean earpiece uses most of the energy, and therefore, the battery life will be determined by silent periods when it is not in use. Similarly, if you use the Monorean Pro in MP3 mode, energy drain is significantly reduced once audio is stopped by pressing the pause MP3 pushbutton.
The following table provides estimates of battery life based on the type of usage:
| Type of use of the Monorean Pro | Battery life |
|---|---|
| Your partner never stops talking, at maximum volume | 6 hours |
| Your partner never stops talking, at saturated volume (*) | 5 hours |
| On a call, neither you nor your partner are talking | 19 hours |
| On a call, you talk but your partner stays quiet | 20 hours |
| On a call, your partner talks 50% of the time (50% silent) | 15 hours |
| Waiting for a call or stand by | 19 hours |
* Depending on the audio type, when the volume is set to the maximum, you may hear a slightly blurry or fuzzy sound (saturated sound). As a result, volume level before experiencing this slight fuzziness is considered the maximum volume. It’s best to turn down the volume until the sound is crystal clear if you hear a saturated sound. Remember that switching from saturated to maximum sound has no effect on the perceived sound volume, but it does have an impact on the battery life.
There is no difference in perceived volume between saturated and maximum sound, but it does affect battery consumption.
