A Module Status report (Modstat) under
Core
(or
Main
)
board hardware
•
A QR code, serial number, and MAC address printed on a sticker on the cover

A laser-etched number and QR code on the inside circuit board.

To replace the TV-UC561's fuse
The TV-UC561 has one fuse.
If the TV-UC561's power
LED is not lit, this could be due to a blown power fuse.
If you suspect a fuse is blown, remove the fuse as described below, and use a multimeter to check it. If the fuse is
blown, try to determine why it blew before you replace it. Check the power wiring polarity of the TV-UC561 and any
other devices that share the power supply. Use the same polarity for all of them.
You can purchase the 3 A, fast-acting, 5mm x 20mm glass fuse from Littelfuse, mfr part #0235003.HXP.
