Public indexed table was independently read. Direct page redirects to access shell and is not bypassed. Requires compatible Logi Options+ host software and signed-in account.

Converted exactly to 295.9 x 135.9 x 32.0 mm and stored as width 295.9 (long side), depth 135.9, height 32.0 (thickness). The business sheet prints 296 mm L x 136 mm W, which agrees, but prints 322 mm H. That figure does not fit a flat box and is read as a typo for about 32 mm, so the consumer sheet height is used.
