Operating notes

Disconnect the OPC-2350LU or a USB cable when it is not in use. Connecting a cable increases the power consumption of your Android device.
The RS-MS1A program may lock up when transmitting some high-quality or large size images, or continuously operated for a long time. In this case, restart the program.
Depending on the Android device, the power supply to the USB terminal may be disabled while in the display sleep mode or power-saving mode. If you have such a device, check the “Screen timeout” check box on the Application Setting screen of the RS-MS1A.
When starting the RS-MS1A program, select a transceiver to connect to.
When you transmit an image with the baud rate set at 4800bps, some of that data may be lost. In this case, set the baud rate to over 9600bps in “Baud rate” on the Application Setting screen of the RSMS1A to match the transceiver’s setting.
If the Menu item does not fit into your Android device screen, change the font or font size.
When using ID-31A PLUS/ID-31E PLUS, ID-51A (PLUS2)/ID-51E (PLUS2), or IC-9700, you cannot use the RS-MS1A and RS-MS3A at the same time.
If the application requires some permissions, you need to grand permissions to use some functions. For operations of the Android device, read the Android device’s instruction manual.
