  • Page 628: Exchanging The Buffer Battery

    18.4 Exchanging 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 battery: Caution: Danger of life! To exchange the buffer battery, first switch off the TNC!
