What do I have to do if precipitates are visible in the lysis buffer (well 1 of the reagent cartridge [RCB])?

Place the reagent cartridges (RCB) into a shaker–incubator, and incubate at 30–40°C with mild agitation for up to 2 hours. Do not use the reagent cartridges (RCB) if the precipitates do not redissolve.
