Suunto Vytec DS [41/86] Warning

You are able to preset alarms before the actual dive. The user program-

mable alarms can be set for maximum depth, dive time and time. The

alarms activate when:

• The preset maximum depth is reached

• continuous beep series for 24 seconds or until any button is

pressed.

• the maximum depth blinks as long as the present depth value

exceeds the adjusted value.

• The preset dive time is reached

• continuous beep series for 24 seconds or until any button is

pressed.

• the dive time blinks for one minute, if no button is pressed.

• The preset alarm time is reached

• the current time is shown.

• continuous beep series for 24 seconds or until any button is

pressed.

• the current time blinks for one minute, if no button is pressed.

OXYGEN ALARMS IN NITROX MODE

Three double beeps and the backlight activated for 5 seconds

occur, when:

• the OLF bar graph reaches 80%. The segments exceeding the

80% limit start to blink (Fig. 3.24.)

• the OLF bar graph reaches 100%.

The blinking of the segments exceeding 80% will stop, when the OLF is

not loading anymore. At that point the PO

is less than 0.5 bar.

Continuous beeps for 3 minutes and the backlight activated

for 5 seconds occur, when:

• the set oxygen partial pressure limit is exceeded. The maximum

depth is replaced with a current blinking PO

value. You should

immediately ascend above the PO

depth limit (Fig. 3.24.).

NOTE! When the backlight is turned OFF, it does not illuminate when an

alarm is activated.

WARNING!

WHEN THE OXYGEN LIMIT FRACTION INDICATES THAT THE MAXI-

MUM LIMIT IS REACHED, YOU MUST IMMEDIATELY ASCEND UNTIL

THE WARNING STOPS BLINKING! Failure to take action to reduce

oxygen exposure after the warning is given can rapidly increase the

risk of oxygen toxicity and the risk of injury or death.
