AUDIBLE ALARM
Most warning situations that activate the Audible Alarm while operating in NORM or GAUG Mode will sound 1 beep per second
for 10 seconds, or until the situation is corrected, or it is acknowledged by pressing and releasing the S button (less than 2
seconds). After being acknowledged and the situation corrected, the Alarm will sound again upon reentry into the warning situa-
tion, or entry into another type of warning situation.
FREE Dive Mode has its own set of Alarms which emit 3 short beeps either 1 or 3 times that cannot be acknowledged or set Off.
The Audible will not be active if it is Set OFF (a group A setting).
Situations that will activate the NORM/GAUG 10 second Alarm include -
• Descent deeper than the Max Depth Set Point selected.
• Dive Time Remaining at the Set Point selected.
• Elapsed Dive Time at the Set Point selected.
• High PO2 of 1.60 ATA or the Set Point selected for the Gas in use.
• High O2 of 300 OTU (single or daily exposure).
• Nitrogen Bar Graph at the segment Set Point selected.
• NORM/GAUG Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18 M), or 30 FPM (9 MPM) at 60 FT (18
M) and shallower.
• Entry into Decompression Mode (Deco).
• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes).
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required).
• Delayed Violation (Maximum Operating Depth of 330 FT/100 M is exceeded).
• A Gas Switch to another tank would expose the diver to PO2 greater than 1.60 ATA.
• Watch Daily Alarm reaches time set (disabled during Dive Modes).
• Watch Mode Countdown Timer reaches 0:00.
A single short beep (which cannot be disabled) is emitted for the following -
• Upon completion of a Hot Swap battery change.
• Change from Delayed to Full Violation 5 minutes after the dive.
3 short beeps (which cannot be disabled) are emitted for the following -
• NORM/GAUG Ascent Rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than 60 FT (18 M), or 26 to 30 FPM (7.5 to 9
MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set On).
• FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times.
• FREE Dive NIBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Permanent Violation) - 3 beeps 3 times.
• Free Dive Mode Countdown Timer reaches 0:00 - each 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be followed by a 5 second steady beep that will
not turn off when acknowledged -
• Ascending above a required Decompression Ceiling Stop Depth for more than 5 minutes (referred to as a Delayed
Violation).
• Decompression requires a Ceiling Stop Depth of 70 FT/21 M or deeper.
• Being on the Surface for 5 minutes after a Conditional Violation.

BACKLIGHT

To activate the Backlight - press the L (lower/right) button.
• The Backlight will activate and illuminate the display for button depression time* plus the user set Duration time of 0, 5, or
10 seconds, for a maximum of 20 seconds.
(*The Backlight turns Off if the button is held depressed for more than 10 seconds.)
• Press the button again to activate as desired.
NOTE: Extensive use of the Backlight reduces Battery life. Also, the Backlight does not operate during
a Low Battery condition or when the Talis is connected to a PC or Mac.
POWER SUPPLY
The Talis uses (1) 3 volt CR2430 Lithium Battery. Used as a Dive Computer, the battery should operate normally for 1 year or
300 dive hours if 2 dives are conducted during each dive period. Voltage is checked every 2 minutes on the surface.
• If voltage of the Talis decreases to the Warning level (2.75 volts), the Battery icon will appear on Surface display screens
(Fig. 5a) as an indication that the Battery should be changed prior to commencing a series of dives.
• If the Talis's voltage decreases to the Alarm level (2.50 volts), the Battery icon will flash and the graphics CHG > BAt will
alternate (Fig. 6a) for 5 seconds, then operation will automatically revert to the Watch Default Time screen. The Talis would
then only operate in Watch modes until the Battery becomes completely depleted.
• Low Battery conditions are not displayed during dives.
• If a Low Battery Condition was not displayed prior to starting a Dive, and a Low Battery Condition occurs during the dive,
there will be sufficient Battery power remaining to maintain operation for the remainder of that dive.
