Power Management

About Power

With a sufficiently charged battery, the device will power on when the power button is pressed (see Figure 6-1 - Power Button). The device will also power on when connected to USB power. In USB mode the device will remain in full power mode to provide power to device. If a power-off sequence is initiated, the device will reboot and remain in full power mode.

How to Charge the Battery

Per UL requirements, the device is designed to not recharge its internal battery when the external temperature is below 0°C or above 40°C.

DynaFlex II Go products have an optional rechargeable battery to supply their own power when they are not powered through the USB-C port. The battery must be periodically recharged by connecting the device to a USB port or stand-alone USB charger. The device requires a USB power supply that can provide at least 500mA @ 5V.

To charge the device, connect it to a USB-C charger or a USB host as described in section 4.3.1 How to Connect DynaFlex II Go to a Host Computer via USB-C. For best results, use the cable that is included with the device. When charging, make sure the device is receiving enough power from the USB connection (the battery level should increase even when the device is in use). A full recharge cycle for a completely drained battery depends on the charging method. From a host USB port at 500mA, full charge takes approximately 5 hours. From a dedicated wall charger, a full charge may take approximately 5 hours. After connecting the device to a power source, make sure the LEDs indicate the device is charging (see sec - How to Connect DynaFlex II Go to a Host Computer via USB-C)

For important information about the device’s power systems, optimal charging methods during regular use, optimal handling and storage, and other information about keeping the device’s power systems in the best possible condition, see section - Handling to Avoid Accidental Tamper and section About Power.

How to Power On / Wake Up from Standby Mode / Power Off

To power on the device connect the device to USB power. To power off the device, disconnect the device from USB power. Press and hold the power button (see Figure 6-1 - Power Button) on the device (for two beeps), all LED indicators should power off and remain unlit. If all LEDs are off, the device is in Powered Off mode. It is important to note the device cannot be powered off when connected via USB.

About Maintenance Reset

DynaFlex II Go will automatically reset once every 24 hours if it is continuously powered on.
