detected and the battery status will be displayed. The battery gauge provides an
estimated indication of battery charge level/remaining charge time. The coloured

to the very approximate voltages and estimated charging times as follows:

The Actiheart 4 uses a lithium rechargeable battery. The maximum voltage is
3.0V. However a rapid drop to 2.75 volts is normal. When fully charged the
battery will last about 21 days when doing a long term recording. The battery life
in the short term recording mode is only 4 days due to the LED flashing with
every heart beat.
IMPORTANT NOTES ABOUT USB CHARGING:
•
Many Computers have power saving functions which shut down all or part
of the PC after a period of time
– this will stop the charging of the
Actiheart.
•
Un-powered USB hubs can have an output voltage below that required
for Actiheart charging.
•
For reliable charging of the Actiheart, CamNtech recommend using the
supplied mains power supply (see section below).
