11 Other Functions
11.1 Memory and Real Time Clock Backup Battery
A lithium backup battery powers the static RAM and the real time clock when input power is removed. This
battery should be replaced annually.
The LNL-3300-M5 is typically shipped with an insulator installed between the battery holder and the
battery. Remove the insulator from the battery holder after installation. Reinstall the insulator if the
LNL-3300-M5 will be stored for a long period of time.
Use battery types BR2325, CR2325, BR2330, or CR2330.
Note: If data in the static RAM is determined to be corrupt after power up, all downloaded
configuration database is considered invalid and is erased. All configuration data must be re-
downloaded.
11.2 Bulk Erase Function
Use the bulk erase function to:
- Erase all configuration and cardholder database (sanitize board).
- Update OEM default parameters after OEM code has been changed.
- Recover from database corruption causing the LNL-3300-M5 to continuously reboot.
Note: If clearing the memory does not correct the initialization problem, contact Technical Support.
To use the bulk erase function:
1. Set the S1 DIP switches as follows:
• 1 and 2 = ON
• 3 and 4 = OFF
2. Apply power to the LNL-3300-M5.
3. Watch for LEDs 1 and 2, and 3 and 4 to alternately flash at a 0.5 second rate.
4. Within 10 seconds of powering up, change switches 1 or 2 to OFF. If these switches are not changed, the
LNL-3300-M5 will power up using the OEM default communication parameters.
5. LED 2 flashes to indicate that the configuration memory is being erased. Full memory erase takes
approximately 60 seconds.
6. When complete, only LEDs 1 and 4 flash for 8 seconds.
7. The LNL-3300-M5 reboots 8 seconds after LEDs 1 and 4 stop flashing (no LEDs are on during this
time).
Do not remove power when performing this procedure.
