hazardous live conductors are exposed.
• Do not touch voltages >30 V ac rms, 42 V ac peak, or
60 V dc.
• Remove the batteries if the Product is not used for an
extended period of time, or if stored in temperatures
above 50 °C. If the batteries are not removed, battery
leakage may result.
• The battery door must be closed and locked before
