Inserting/Charging The Rechargeable Battery - VOLTCRAFT Gamma Check Pro Notice D'emploi

8. INSERTING/CHARGING THE RECHARGEABLE BATTERY

For operation of the "Gamma Check Pro", a lithium rechargeable battery (type 18500) is enclosed. This is automati-
cally charged if there is a USB connection present via the mini USB cable.
The charge condition of the rechargeable battery is displayed in the lower right of the display in the form of a
rechargeable battery symbol. When charging the rechargeable battery, the individual segments in the rechargeable
battery symbol will fill up from the bottom upwards to indicate charging or the current condition.
Inserting/Charging the Rechargeable Battery:
At delivery, the rechargeable battery is already in the battery compartment of the "Gamma Check Pro" for reasons of
transport protection. It is secured against premature discharge or deep discharge with a small plastic insulation strip.
To start operation, open the battery compartment, then pull out the plastic insulation strip. Close the battery compart-
ment again.
If the rechargeable battery is too weak in operation (or the device determines more than 600 pulses per
second), this leads to automatic interruption of all measurements and the message "Error" is output. In this
case, the rechargeable battery must be charged.
The "Error" message can be removed/reset with any button.
Charging the Rechargeable Battery:
Connect the device to a USB mains adapter via a USB cable. You can also use the USB port of your computer or a
USB hub with a separate mains adapter for this.
It is important that the USB port can provide a current of 500 mA.
When the USB cable has been connected for charging and the rechargeable battery is discharged very
strongly, it is possible that the "Gamma Check Pro" cannot be switched on. In this case, only the frame of the
rechargeable battery symbol will still be flashing in the display.
In this case, give the device enough time to charge the rechargeable battery. Once the bars in the recharge-
able battery symbol start flashing, the device can be operated again normally.
