I've found it works best with 1.5v alkaline batteries or the 1.7v lithium batteries. But the computer will often say the batteries are low, because the voltage on AA rechargeables are lower.

    I had a look at the link via Google Translate- am I right in thinking it is believed the diver is trapped in a (possibly dry) sump beyond a cave collapse and they are trying to dig him out with assistance from cavers all over Europe? (Apologies if this is wrong) If correct I send prayers and crossed fingers to all involved, what a fantastic effort from you all, I hope your heroic effort is rewarded. Some info, in English, is here. I read this this morning.

    Like Ben, I hope that the brave efforts are fruitful. Good luck all, Phil.

    From Monday, Oct 4, 4:30 PM ET 'Eric Establie, a French cave diver who left on a difficult exporation dive Sunday morning (French time = + 6 hours from our Eastern US time), has not returned.' 'The British rescue dive team returned during the night. They found the passage obstructed by a gravel landslide at 780 meters from the entrance. Eric’s emergency scooter was found wedged in the obstruction, facing the exit. Various clues led to the assumption that Eric had tried but was unable to cross the obstacle, then left his scooter to indicate that he was alive and had returned to a spot out of the water where he could take refuge and wait for rescue.' And today: 'Very good news at 19:00 hours local time. The divers that went in today found a sign of life from Eric.

    He has placed a twinset on the same site that they originally found his scooter. This guy is still diving (from his hide out obviously behind the blockage) and sends us as message! He seems to be anxious for the rescue teams to get him out;-)' and 'However: on an even better note; I just saw footage of TF1 (French TV) where the guy in charge of the rescue operation talks about contact via tapping. SOS and other tapping signals were exchanged by the two divers that went to the 780 meter point and Eric Etablie. A new dive will be undertaken tonight to bring him supplies (food and gas as I understand it).' This just might end up being a succesful rescue.

    Does various Rescuers are trying to send food 'More than ever, we are hopeful.' Labastide A-de-Virac, rescuers are now convinced that Eric is alive Establie. The caver would have survived the landslide occurred last Sunday in an underground gallery of the gorges of Ardeche. Yesterday afternoon, two divers were again rushed into the cave. At the height of the landslide, they filed it sealed chambers containing messages, watch, food and oxygen. 'You can pass through the rubble cylinders,' said Olivier Lanet rescuer.

    A second team has to dive today to ensure he could pick up the boxes from the air pocket where he took refuge. 'We hope it has enough oxygen to dive,' said the rescuer.

    SOS in Morse All changed Saturday afternoon. While rescue workers were examining the plateau overlooking the gorge with a vibraphone, they heard shots accidentally hit on a rock. 'It can not be reflected, says Eric Zipper, the Cave Rescue. Scientific toolworks understand. When two blows were struck, a shot was heard in response.

    When we hit SOS in Morse, there were two shots. ' If they continue to clear a natural chimney, rescuers have also begun to dig vertically another channel to send messages and materials. 'We try to make contact with him,' said Eric Zipper. The best solution is to reopen the crossing by removing the rubble. 'Aider Olivier Lanet is optimistic about him:' By the weekend, we believe we will get him out. Click to expand.Not a ledge, but out of the water.

    It's based on him taking refuge in a sump (an air filled chamber) located at about 1400 meters (4500') penetration. Keeping him supplied would seem very problematic. From what I can tell, they can only deliver supplies to him through a small opening at the collapse site.

    Based on the cave profile, it appears that he would have to swim 1800' at a depth of around 200' in order to pick up supplies from the sump side of the collapse. That is a significant dive to have to repeatedly plan and execute with minimal supplies after being in a sump for a week. Each time they make a delivery, they would also need to supply him with more dive gas/gear so that he can make the next trip for supplies.
