M680i and M685i Software Upgrades
The M680i and M685i do not require separate firmware packages. M680i/M685i software is
embedded within the respective phone's firmware package.
When the M680i or M685i is connected and is powered up (for the M680i the LED corresponding
to the second button will turn solid red indicating it is powered up; for the M685i the LCD screen
will turn on) the module will check to see if an upgrade is required . If it does not have the latest
software, the module will upgrade itself using the phone's embedded firmware.
For the M680i, this process will take approximately 10 seconds, in which case the LED
corresponding to the second button will stay solid red for the duration. If the upgrade is
successful, the LED will turn green. If the LED stays solid and red for longer than 10 seconds,
the upgrade may have failed. In such scenarios, unplug and reattach the power source from
the phone to attempt the upgrade again.
As software upgrades on the M680i are performed one at a time, each additional module
connected increases the approximate upgrade time (e.g. three connected M680i expansion
modules will take approximately 30 seconds to upgrade).
For the M685i, the upgrade process will take approximately 7 to 10 minutes, in which case an
upgrading icon will be displayed on the module's LCD screen and an upgrading message will
be displayed on the phone's LCD screen. If the upgrade is successful, the module's LCD screen
will refresh with the softkey images. If the screen is not refreshed after ~15 minutes, the upgrade
may have failed. In such scenarios, unplug and reattach the power source from the phone to
attempt the upgrade again.
Unlike the M685i, software upgrades for the M685i are performed simultaneously and therefore
do not increase the upgrade time (e.g. three connected M685i expansion modules will still take
approximately 7 to 10 minutes to upgrade).
When using a combination of modules in tandem, the process of upgrading should take
approximately 7 to 10 minutes as well.
