Supercap Power Backup
The wrist computer has a supercap power backup to prevent data loss during battery
replacement. The supercap backup provides sufficient power to preserve memory contents
for approximately 15 minutes while the batteries are replaced.
Note: The supercap does not provide enough power to operate the wrist
computer. Replace or recharge the primary batteries immediately
upon receiving a dead battery message.

1. Power off the wrist computer.
