Scuba Alerts & Alarms 

The alerts will vary depending on the dive mode. 

Start/ End Dive 

Activation Depth 

The dive will automatically start when the descent depth reaches 1.2 meters. 

The dive will end when you ascend to 1.2 meters. 

You can adjust the delay time for ending the dive. 

Depth Alarms 

An alarm will sound upon reaching the set depth. 

You can set up to 10 alerts, and 1 alarm. 

Time Alarms 

An alarm will sound upon reaching the set dive time. 

You can set up to 10 alerts, and 1 alarm. 

Fast Ascent Alert  

An alarm will sound if the ascent speed exceeds 12 meters per minute for more than 5 consecutive seconds. 

Safety Stop

Safety Stop 

When a dive depth exceeds 10 meters, ascending to 6 meters will activate the safety stop. 

Safety Stop Pause 

The effective depth range for the safety stop is between 3 and 7 meters. If the depth exceeds this range, the countdown will stop. 

If the depth exceeds 10 meters during the dive, the safety stop will be reset. 

Safety Stop Clear 

A notification will sound when the countdown is complete. 

Decompression Stops 

Low NDL 

When the NDL (No Decompression Limit) is below 3 minutes, an alert will sound every minute. 

DECO Stop 

Once the NDL reaches zero, the dive will enter decompression status (DECO). During ascent, you must stay close to the indicated depth and perform a decompression stop before surfacing to minimize the risk of decompression sickness. 

The screen indicates a 1-minute stop at 15 meters for decompression. 

Since ascent itself is part of the decompression process, the decompression stop may be completed during the ascent, after which the display will return to the dive status with NDL.

Missed DECO Stop 

If you ascend shallower than the decompression stop depth, a “MISSED STOP” alarm will sound. If air supply allows, please descend below the deco stop depth to complete the decompression. 

Check SPG 

Set the dive time, and you will be reminded to check the remaining air when the time is reached. 

You can set up to 10 reminders. 

CNS Alarm 

A warning will sound when the CNS toxicity loading percentage reaches the set limit. 

PPO2 (Maximum Operating Depth) 

An alarm will continuously sound if the partial pressure of oxygen (PPO₂) exceeds the safety limit (Maximum Operating Depth (MOD). Please ascend immediately. 

Surface Time 

You can set a reminder for the surface rest time after ending a dive, to prepare for the next dive. 

Battery Low 

  • An alarm will sound when the battery is low.
