As software upgrades on the M680i are performed one at a time, each additional module connected increases the approx-
imate 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 dis-
played 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.
