Operation of Charging:

Before the first use, please inset the original fitting DC8.5V external power source into the instrument, and charge for 8-10 hours on ¡§off¡¨ position to make sure the backup battery capacity to be sufficient. When it displays that the voltage of the built-in backup battery is lower than 4.8V, please use the external power source, and charge the backup battery after the use. While the charging is going normally, the red charging indicator light beside the electric outlet turns on. The longer it charges, the larger capacity the built-in battery will have, and the darker the indicator light becomes. The charging time can not be over 11 hours.
