Mio Modero R-4
Battery Low Indicator
When the battery charge level is too low to sustain continuous operation, the Mio R-4’s touchscreen will
display a popup window reading "Battery Low" as an initial warning, and then a popup window reading
"Battery Very Low" to encourage the user to shut it down. The device will then shut down to prevent a
total discharge of the battery. To recharge the battery, insert the Mio R-4 into the Mio Remote Charging
Base (see Charging The Mio Remote with Charging Base section on page 94).
Installing Supported Language Keypads
The Mio R-4 has the capacity to replace its default English keypad with an optional keypad in one of
four languages for Arabic, French, Italian, or Mandarin Chinese readers. To install a new keypad in one
of those four supported languages:
1. Flip and turn the Mio R-4 so that the buttons are facing away from you and the device is upside
down.
2. Holding the Mio R-4 in both hands, place your thumbs on the battery door and push up to slide the
battery door free.
3. Remove the battery.
4. Unscrew the 6 screw points indicated in FIG. 3.
5. Turn the unit over so the buttons are facing you.
6. Lift the top assembly away from the PCB.
7. If necessary, push out the standard buttons from the front of the top assembly.
8. Place your language pad in the top assembly and verify the alignment with the guide posts on the
PCB.
