Does the Explorer ever lock out (cease to function)?
Yes and No. For broken or omitted decompression, the Explorer will lock out for 24 hours after 10 minutes of surfacing with decompression remaining for the dive. At this time an “Err” will be displayed where the TTS/SI/TTF numbers are normally displayed. The Explorer will now function in the gauge mode which will only display depth and time under pressure with no other information. The “Err” will continue to be displayed during a dive in the gauge mode. There are no lockouts while diving.
