BACKLIGHT FEATURE
In addition to using a high contrast LCD for easy readability in low light condi-
tions, the backlight features evenly illuminate the full upper and lower dis-
plays.
Smart Glo™, the surface mode backlight, senses the intensity of light that is
passing through small ports located between the control buttons (Fig. 13). If a
low level of light is sensed, the Smart Glo™ backlight will illuminate the dis-
play for button depression time plus 10 seconds when either button is pressed.
Oceanglo®, the dive mode backlight, will illuminate the displays for button de-
pression time plus 5 seconds when the Select (Right) control button is pressed.
Additional illumination time can be obtained by pressing the button again.
NOTE: Extensive use of the backlight reduces estimated bat-
tery life. Also, the backlight will not activate during a 'low bat-
tery condition', or when downloading data to a PC.
OPERATING TEMPERATURE
The Pro Plus will operate in almost any temperature diving environment in
the world between 32 and 140
°
F (0 and 60
°
C).
