Hi Zei,
I came across the same situation too on my LS-CHL.
Firstly, do you have any data in the LS-CHL?
If no then probably you can try this method.
It works for me after I managed to test it out many times.
You computer's IP is 192.168.11.1.
Connect lan cable to LS-CHL.
Make sure LS-CHL is switched off.
Press and hold onto function button in front of unit.
Power/Switch on the unit.
Keep holding onto function button for abt 10-15seconds.
Let go of function button while function button/led is flashing.
Wait for 10 seconds then press and hold onto function button until Power LED stops blinking
Then wait for abt 10 seconds then press on function button again for abt 10 seconds then let go.
Power LED will be blue then will turn red/pink then back to blue. Takes abt 20-30 seconds for these to happen.
Function LED will still blink. Wait for it to stop.
Once it has stop blinking, anf the Power LED is blue and not blinking, you can run the Nas Navigator to see if it can be detected.
Once it can be detected, yu will see that it is in EM mode.
Update the LS-CHL with the latest firmware.
Good luck!
