Battery

The primary power source for the Dolphin terminal is the 3.7V Li-ion rechargeable battery located under the battery door on the
back panel of the device. Honeywell recommends, you keep the battery in the terminal charged at all times to help prevent data
loss. Letting the battery become fully discharged causes the terminal to lose all data in RAM.
Note: All data in RAM is cleared when the battery is removed. Always power off the terminal before removing the battery to
ensure any changes made are saved to the flash memory.
