I recently ordered a Visitech BP-2000 Series II system for the laboratory. The shipment included replacement tubing (the thin, translucent blue-gray tubes that feed into the actual tail cuff). The inclusion of the tubing in the shipment suggests that the tubing can be replaced independently without involving a specialist, but after reviewing both the Visitech website and the system manual, I can't find any instructions about how to do it. I don't currently need to replace my tubing, but I'd appreciate the security of knowing I'd be able to handle the situation if it arose. Thanks!
