Customized 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. The keypad may also be
replaced with other keypads to support other functions or arrangements of keys. The additional
functions or arrangements are supported with firmware upgrades, available for download at
www.amx.com.
Each of the alternate keypads requires the appropriate firmware download for proper
function; please refer to the Updating Firmware section on page 32 for more
information.
