PDA Quick Troubleshooting Guide
The AquaLink RS PDA will stop communicating

communication is lost the PDA Handheld Remote
will lock on the startup screen until a good link
is again achieved, usually within a few sec onds.
If com mu ni ca tion is not reestablished within
a few seconds or this happens often, use the
troubleshooting in for ma tion in the following table
