SECTION 5: TROUBLESHOOTING AND MAINTENANCE
5.5 Batteries, Charging and Calibration
Charging the Battery
For safety, the device is shipped from the factory with the battery partially charged and in a
shipping mode. At first use, the device must be plugged into the battery charging power supply
before the device can power on. Until the battery gets fully charged for the first time, the battery
charge level indicators will not be accurate. Fully charge the battery until the amber LED stops
blinking before operating the device. Typical charge time is approximately 4 hours for a fully
discharged battery. Higher environmental temperatures will extend battery charging time.
NOTE: When the battery is low, charging for approximately 20 minutes should provide enough
battery to run a typical test.
WARNING!
If the device has been recently subjected to low temperatures below 0 °C or high temperatures
above 40 °C, let the device equilibrate to room temperature for two hours before charging the
battery.
CAUTION:
The electrode cable assembly should never be attached to a patient while the battery is being
charged. Only use the ELITechGroup provided power cord and battery charging power supply to
charge the battery
