The Olympus WS-311M recorder may not be powering on after inserting a new battery due to the following reasons:
1. Incorrect Battery Insertion – Ensure the size-AAA alkaline battery is inserted with the correct polarity as indicated in the battery compartment.
2. Battery Cover Not Fully Closed – The battery cover must be completely closed by pressing in direction A and sliding in direction B.
3. Weak or Depleted Battery – If the battery is old or weak, replace it with a fresh AAA alkaline battery or an Olympus Ni-MH rechargeable battery.
4. Battery Contact Issues – Check for dirt or debris on the battery contacts, and clean them if necessary.
5. Battery Low Indicator – If the display previously showed "Battery Low," the device may have shut down due to insufficient power. Replace the battery promptly.
If these steps do not resolve the issue, further troubleshooting may be required.
