MAINTENANCE
CAUTION
To ensure proper AN/PSN-11 operation when installing or replacing both the power and memory
batteries, ensure the power battery is installed or replaced prior to the memory battery.

Operator maintenance:
• Replace power battery.
• Reset battery used time for accurate remaining time indication.
NOTE: The AN/PSN-11 is NOT to be opened in the field, except to
change batteries Opening the receiver will void the warranty.

Organizational maintenance:’
• Replace memory battery annually.
