. Figure 6: device dimensions (mm) Instructions 1) Switching the device on and off Switch on:

Link the CM20 to a power source via the DC power jack or USB Type B port. Switch off:

Disconnect the CM30 from the power terminal it is connected to. 2) Environmental Conditions 5 1) If any cables become damaged, seek a replacement. 2) Do not insert unknown materials into any port on the CM20, this may cause serious damage to the device. If repairs are required, please contact a professional technician instead of attempting them on your own. Make sure the various cables connect to provide the appropriate voltages at the proper pins. For best performance, the antennas should be placed in an elevated area and kept free from obstructions. 3) 4) 5) This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation.

To install a SIM card, first open the mount by fully depressing the yellow button next to the card slot and inserting a card into the mount. Push the mount back into place to secure the card, and then restart the device to detect it. 2) Antenna is used The CM20 comes packaged with two antennas, one antenna for communicating with Wi-Fi networks, and another is for communicating with 2G, 3G, or 4G networks. These antennas can be attached to the CM20 at the two SMA connectors indicated in Figure 2. Figure 5: connecting the CM20 to the IM20 The CM20 is designed to function as a communications module for other PAX devices. It can connect to devices such as the IM20 POS terminal through its USB port to provide additional functionality. As shown in Figure 5, the USB Type A port of the CM20 can be connected to the USB Type B port of the IM20, both powering the IM20 and allowing for communications between the two devices. This device can provide similar functionality to other POS terminals such as the IM500 and IM700.
