Connectivity 714
Important:
• For each receiving unit, remember to back up information as necessary and install
new batteries.
• Be sure both the sending and receiving units are in the
VAR-LINK screen.
During the transfer, the receiving unit shows how the transfer is progressing. When the
transfer is complete:
• The sending unit returns to the
VAR-LINK screen.
• The receiving unit returns to either the Apps desktop or the Home screen. You may
need to use 8| (lighten) or 8« (darken) to adjust the contrast.
Do Not Attempt to Cancel an Operating System Transfer
After the transfer starts, the receiving unit’s existing OS is effectively deleted. If you
interrupt the transfer before it is complete, the receiving unit will not operate properly.
You will then need to reinstall the OS upgrade.
If You are Upgrading the Operating System on Multiple Units
To perform an OS upgrade on multiple units, download and install the OS into one unit
and then transfer the OS upgrade from one unit to another. This method is faster than
installing it on each unit via a computer. OS upgrades are released free of charge and
you do not need to obtain a certificate before you download or install them.
