• Last for up to 8 hours

• Remove heat pad from its wrapper then give the pad a few good shakes to activate.
• Remove the paper backing of the heat pad and stick pad to the urine bag (please see specific product instructions in order to apply the heat pad properly).
• Once activated, the heat pad will have a life expectancy of 8 hours.

Note that once activated the heat pad will barely fell warm to the touch and this is perfectly normal as the heat pad in combination with your body heat will raise the urine to its ideal temperature within one (1) hour.
