Maintaining the Terminal
Backup Batteries
To prevent data loss during battery replacement, the terminal utilizes a super cap as a backup.
The super cap provides sufficient power to preserve memory contents for approximately 15
minutes while the primary battery is replaced. The super cap does not provide enough power
to operate the terminal. On receiving a low battery message, replace or recharge the primary
battery immediately.
Replacing the Battery Pack
Battery packs available from Symbol are listed below.
Note: The Series 3800 NiCd battery packs, 3872-103, 3872-105, and 3872-
115, CANNOT be used in the Series 6800 terminal.
Removing the Battery Pack
To remove the battery pack (Figure 6-1):
1. Power the terminal off.
2. Press the battery release buttons on both sides of the handle.
