Locating the IrDA Port
Communications ports, also called COM ports, are locations from which data can be
passed into and out of the 5020. You use serial communications through an IrDA port to
communicate with other IrDA compliant devices.
You can also use the IrDA port to communicate with RS-232 devices, such as modems,
PCs, and printers, using a D5020 serial communications dock or L5020 serial
communications adapter.

Learning About the 5020’s Batteries
There are two rechargeable batteries in the 5020 PC:
Main Battery Pack
This lithium-ion battery provides the main power source to operate
the 5020.
Bridge Battery
This manganese-dioxide lithium bridge battery backs up all memory
and the real-time clock while you change the main battery pack.
Main Battery Pack
The main power source for the 5020 is a lithium-ion battery pack. Follow these tips to
get the best battery performance and life possible:
•
You should always keep a charged main battery pack installed in the 5020 to
maximize the bridge battery’s life.
•
When you remove the main battery pack, insert another charged main battery pack
in the 5020.
•
Keep a spare charged main battery pack available so you can continue to operate the
5020 without interruption.
•
If you use the 5020 for extended periods of time in a sub-freezing environment, you
may need to change the main battery pack more often.
