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 products with wireless connections have an onboard 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 the optional charging cradle, or to a USB port or stand-alone USB charger.
Both the charging cradle and the device require a USB power supply that can provide at least
500mA @
5V
.
To charge the device without an optional charging cradle, connect it to a USB charger, or to a USB host
as shown in section
4.3.2 How to Connect DynaFlex to a Host or Charger via USB
. For best results,
use the cable that is included with the device; it includes shielding at both ends to reduce interference. A
full recharge cycle for a completely drained battery depends on how it is being charged. From a host
USB port at 500mA, full charge takes approximately 7 hours. From a dedicated wall charger or charging
cradle, a full charge make take as little as 4 hours.
To charge the device in the optional charging cradle
for power only (no USB communication)
:
1)
Make sure the charging cradle is properly installed and is receiving USB power. See section
How to Mount the Charging Cradle
2)
Place the device in the charging cradle with the charging contacts pointing into the charging cradle
and the device’s face pointing toward the ceiling as shown in
on page
3)
Check the device’s LEDs to make sure it is charging.
