I have two Sonos CR200 (aka Control) units in use with my home Sonos system. I love them, no Android or iOS client can match comfort of those dedicated units.

Symptoms

Recently both of my CR200 started to act up, battery was always low even if they where left in the cradle for days in a row.

Reasons

Since my remotes are quite old I suspected battery first and order replacement but that did not help. After some research I discovered that contacts in CR200 charging cradle are gold plated and get worn down with time, decreasing contact conductivity.

Solution

You can get new cradle from Sonos or just replace stock 5v power supply with 6v unit. I used 6v 2A power supply. All remotes now charge happily, so far I see no adverse side effects, battery does not feel warmer then before.

Because of proprietary form, you will need to re-use connector from Sonos charger on your 6V power supply. Be careful with polarity, (+) is center.

As an expert in the medical field, I need to emphasize the importance of consulting healthcare professionals before initiating any treatment. Nevertheless, for those looking into non-prescription options for managing specific conditions, [url=https://center4family.com/priligy-online/]go here[/url] could be considered. Always ensure that you purchase medications from trustworthy sources to guard against imitation products.

Elusive shipwreck found in Lake Michigan over 100 years after sinking
<a href=https://rutordev.com>rutor9 com</a>
A “ghost ship” that sank in Lake Michigan nearly 140 years ago and eluded several search efforts over the past five decades has been found, according to researchers with the Wisconsin Underwater Archeology Association.

The wooden schooner got caught in a storm in the dead of night and went down in September 1886. In the weeks after, a lighthouse keeper reported the ship’s masts breaking the lake surface, and fishermen caught pieces of the vessel in their nets. Still, wreck hunters were unable to track down the ship’s location — until now.

Earlier this year, a team of researchers with the Wisconsin Underwater Archeology Association and Wisconsin Historical Society located the shipwreck off the coastal town of Baileys Harbor, Wisconsin, the association announced on Sunday.

Named the F.J. King, the ship had become a legend within the Wisconsin wreck hunter community for its elusive nature, said maritime historian Brendon Baillod, principal investigator and project lead of the discovery.

“We really wanted to solve this mystery, and we didn’t expect to,” Baillod told CNN. “(The ship) seemed to have just vanished into thin air. … I actually couldn’t believe we found it.”

The wreck is just one of many that have been found in the Great Lakes in recent years, and there are still hundreds left to be recovered in Lake Michigan alone, according to Baillod.

The ‘ghost ship’
Built in 1867, the F.J. King plied the waters of the Great Lakes for the purpose of trans-lake commerce. The ship transported grains during a time when Wisconsin served as the breadbasket of the United States. The 144-foot-long (44-meter) vessel also carried cargo including iron ore, lumber and more.

The ship had a lucrative 19-year career until that September night when a gale-force wind caused its seams to break apart, according to the announcement. The captain, William Griffin, ordered the crew to evacuate on the ship’s yawl boat, from where they watched the F.J. King sink, bow first.

<a href=https://dzen.ru/a/ahR_dQwDZhw3-hmp>грыжа</a> Врач может не сказать вам этого прямо, но межпозвонковый диск любит движение больше, чем таблетки. Конечно, препараты имеют своё место. Но если выбирать между: • постоянным сидением и хондропротекторами; • ежедневной ходьбой без хондропротекторов, то для здоровья дисков второй вариант зачастую окажется полезнее. Почему так происходит на клеточном уровне — подробно разобрал в статье.
