Active Backlight - Uwatec Aladin TEC 3H User Manuals

System and operation
• If the bar graph shows 2 segments, the battery symbol will blink, on the surface and in dive
mode, to alert the diver of a dangerous situation: the battery may not have enough energy to
finish a dive.
• Replace the battery when the steady battery symbol appears (3 segments)!
F
The temperature influences the battery performance. In cold water it is lower than in
warm water. If the battery shows 4 segments on the surface, it is possible for it to
drop to 3 segments during the dive. If this is the case, the backlight will be tempo-
rarily disabled. See below.
Bar graph
interpretation
Aladin TEC 3H marks dives started with 3 or less segments in the logbook with the battery symbol.
Logbook information is not lost even when the battery is removed for a long time.

Active backlight

The display of Aladin TEC 3H can be illuminated both on the surface and underwater.
The backlight can be activated by pushing
settings: Set 1 -> Light.
The backlight can only be activated if the computer display is on.
F
Repeated activation of the backlight will reduce battery life.
F
Keeping the backlight permanently on represents a severe strain on the battery. In warm
waters (20 °C/68 °F and above), a new battery can sustain 20-40 1-hour dives with the backlight
always on. In cold waters (4 °C/40 °F and below) the low battery warning may come on within the
first dive. For temperatures between 4 °C/40 °F and 20 °C/68 °F the life of a new battery will be
somewhere between 1 and 20 1-hour dives. Aladin TEC 3H monitors the battery level throughout
every dive, and if the available energy drops below the warning threshold, Aladin TEC 3H will
automatically disable the backlight to prevent a computer shut down.
