Battery Life
We have tested the following batteries under normal and extreme operating
conditions. The following operating times are averages and can vary depend-
ing on age of battery, temperature and other factors.
Normal conditions (designed to simulate operating conditions when scuba
diving):
1. Turn camera on, take a test picture. Set to Sea Mode. Put in housing, close
housing.
2. 90 minutes later: Turn power on. Take three pictures on land. 10 Minutes
later: Take pictures underwater for 45 Minutes, not continuously, but every
2 Minutes, =23 pictures.
3. Wait for 1 hour, then take 20 underwater pictures in 40 Minutes.
4. Wait for 2 hours, then repeat step 2 and step 3.
5. Then repeat 3.
Extreme conditions (designed to test the power consumption in the most
extreme operating conditions.)
1. Turn camera on, Set to External FLASH mode. Put in housing, close housing.
2. Take picture intervals as quickly as possible (display always ON, FLASH
always fires)
