The external speaker jack accepts a 3.5mm (1/8")mono (2-conductor) plug.For voice communications, connect a microphone equipped with an 8-pin modular plug into the modular socket on the front of the main unit. Press rmly on the plug until the locking tab clicks. Attach the supplied microphone hanger in an appropriate location using the screws included in the screw set.To utilize the optional QPS-778 software, you must rst connect the transceiver to your PC then using an optional programming cable PC50 (via Data socket ).Please use QPS-778 software for programming.External speaker adopt double port BTL, please care about the connecting way. The speaker can not connect with the ground, otherwise the speaker will be fault.
