When the backlight is on, pressing the button will 
prolong illumination of the display.
 
WARNING
Temperature can noticeably affect battery 
voltage. The icon that signals a low battery 
level may appear due to low temperatures, 
even if the battery still has sufficient 
capacity. In this case, backlighting is 
disabled.
If backlighting has been disabled due to low 
temperature, you can repeat the battery status 
check by entering System mode. 
If the battery icon disappears, the backlighting 
function has been re-enabled.
 
WARNING
We recommend that you replace the 
battery if you intend to dive in cold water.
