The AC power should be in the range of 86-264V 50/60Hz. Do not use the AC power outside of this
range.
◆Use of Ni-MH Batteries

260 minutes.
When charging is completed, put the batteries into the instrument in the correct directions.
Battery life is about 3 hours, but it will vary by the type and capacity of battery, or status of
