15.5 Changing the Buffer Battery
A buffer battery supplies the TNC with current to prevent the data in
RAM memory from being lost when the TNC is switched off.
If the TNC displays the error message Exchange buffer battery, then
you must replace the batteries. The buffer batteries are located next
to the power supply unit in the logic unit (round, black case). The
TNC also has an power storage device that provide the control with
current while you are exchanging the batteries (for a maximum of
24 hours).
To exchange the buffer battery, first switch off the TNC!
The buffer battery must be exchanged only by trained
service personnel!
