Installing Batteries and Turning on the Power
Caution when using battery power on the R-44
• If you operate on battery power for an extended time, the batteries will become hot. Be careful not to 
burn yourself.
• Do not mix new batteries with used batteries or mix batteries of differing types.
• If you will not be using the R-44 for an extended time, we recommend that you remove the batteries to 
prevent leakage or other accidents.
• When using a USB cable to connect the R-44 to your computer, use the AC adaptor to prevent the loss 
of power while the connection is active.
