CHARGING BASICS
Before using the system for the first time, charge the receiver (HR310) for a complete charging cycle
without interruption. If your system comes with re-chargeable transmitters (HM312), a transmitter
charger is supplied along with your transmitter package. Rechargeable transmitters (HM312) must
be fully charged each time you start a new monitoring session. Otherwise, your sensor will likely not
remain operational until the end date of sensor wear period (14 days).
A complete charging cycle of the receiver (HR310) takes about 4 hours. For the re-chargeable
transmitter (HM312) it takes about 2 hours when using the supplied USB adapter plugged into a
standard household electrical outlet (100 to 240 VAC, 50/60Hz). It is recommended to use only the
supplied USB cable and USB power adapter. To ensure the best performance every day, all day,
plug in your receiver (HR310) to its charger at the end of the day and charge it up overnight.
