F.H.Papenmeier 1860-TRIO Manuel D’Utilisation

Sleep Time 
BRAILLEX Trio will automatically switch off after a period of inactivity defined in 

the device settings. When you first get the device, this period is 10 minutes. In 
order to reactivate the device, press the on-off switch. 

Battery Handling 
BRAILLEX Trio comes with a set of four rechargeable AA type NiMH batteries. 

Please make sure that before you start using the device, you first charge the 
batteries. 

 
With freshly recharged batteries, BRAILLEX Trio has an operation time of ca. 20 
hours; in Bluetooth operation, you have 10 hours autonomy. Please note that 

even if the device is switched off, it will use a minimal amount of energy. So if 
you know that you will not use BRAILLEX Trio for a longer period, we suggest 

that you take the batteries out. All data will be safe then, the only thing to do 
after you put the batteries in will be to set date and time again, as the internal 

clock does not have a separate battery buffer. 
 

A number of factors will influence the battery autonomy. A very important one is 
the Bluetooth module inside the device that drains an important amount of 
energy. By default, this Bluetooth module is active when you first switch on 

BRAILLEX Trio. If you do not use it, it makes sense to disable it in order to save 
energy. This is how you proceed: 

 
•  From the BRAILLEX Trio Control Center, select "settings", "bluetooth 

settings", "bluetooth on/off" and chose "bluetooth off". Confirm with Enter 
(Space + dot 8, or simply dot 8) or push the Easy Access Bar 2 steps down. 

Recharging the Batteries 
You have two possibilities to recharge BRAILLEX Trio's batteries: 
 

•  If you use NiMH batteries (one set of those is provided with the units), you 

can recharge them inside the unit connecting the provided charger with the 

USB port of the device; 

•  You can also take the batteries out and recharge them in a separate charger. 

Recharging the Batteries Inside the Unit 
If you want to recharge BRAILLEX Trio's batteries inside the unit, use the 

provided charger. It is marked with the word "trio" in Braille, it connects to the 
power outlet via a 3 conductor detachable cord, and to the BRAILLEX Trio via 
USB cord. For recharging the batteries, please keep in mind a number of rules: 

 
•  You have to use the external USB charger. It is not possible to charge the 

batteries while BRAILLEX Trio is connected to a computer via its USB port — 
the USB specifications do not allow draining sufficient energy to both run the 

device and charge the batteries. BRAILLEX Trio is able to detect a computer 
connected to it and will abort the recharging operation with an error 

message. 

•  You must have the right battery type inside the unit. Please make sure not to 

try and charge Alcaline batteries! Trio will most likely detect those and abort 

the charging with an error message, but it might be safer not to try. We 
strongly suggest the use of NiMH batteries. 

Caution: If there are no batteries inside the unit when you UNPLUG the 
charger, you may lose BRAILLEX Trio's memory! 

•  It is not sufficient to plug in the charger; you must also activate the charge. 

Select "tools" from the Control Center, then "battery recharge", and "battery
