The HeartStart OnSite Trainer features the same clear and reassuring voice prompts and instructions as the operational
Philips OnSite,
in addition to pre-configured scenarios. The Philips HeartStart OnSite Trainer is also designed to
look significantly different than the operational
Philips OnSite, preventing accidental use during an emergency.
Please note that the Philips HeartStart OnSite Trainer requires four "AA" batteries, which are not included.
