Precautions Prior to Using the Multicharger
Read before charging VS-XHR Heart Rate Sensor!
Description
The purpose of the Multicharger is to charge multiple VS-XHR Heart
Rate Sensors. An AC to DC converter is provided which powers the
device. Up to three VS-XHR Sensors can be mounted on the
Multicharger, providing a full charge within 11 hours (typical).
Cautions
The DC plug on the Multicharger power supply, or the AC power cord on
the power supply, both serve as the cutoff switch for power to the
Multicharger. Ensure that the socket-outlet providing voltage to the power
supply is located nearby and is readily accessible.
Always use the supplied AC power cord with the Multicharger. Do not
substitute power cords other than the one supplied with the Multicharger.
