    Changes fr​om Release E5

    Fixed the problem where the call-ending frame may not be sent when transmitting the D-PRS DV-A or NMEA DV-G position data in the DV mode using Release E4 or Release E5 firmware.

    Release E6 fixes the following problems.

    The call-ending frame was not sent after releasing PTT. This caused a delay in sounding the standby beep from the receiving transceiver.

    The repeater does not stop transmitting the downlink soon after the transceiver finishes transmitting the uplink.

    To update the firmware

    Thoroughly read " Firmware update instructions " and follow the instructions in it.

    An OPC-2350LU, OP​C-1529R or OPC-2218LU is required to install the firmware update. To use the OPC-2218LU for the first time, a USB driver is required. Download the driver here .

    Making a backup file of programmed contents and settings before updating the firmware is recommended.

    The CPU M firmware will be updated to 1.21.
