The IC Certification Number listed in the case back of certain GW-B5600 G-SHOCK products may contain an error:

Error IC:23888-S0DW

Correction IC:2388B-S0DW

GW-B5600 otherwise complies with applicable Canadian radio standards and is certified for use in Canada. Newly manufactured GW-B5600 units will bear the correct IC Certification Number going forward.
