43FT-70DR/DE Advance ManualFunctions to Use as NecessaryUsing the Transceiver for Packet CommunicationYou can perform packet communication with your transceiver by connecting a TNC (Ter-minal Node Controller) using an optional Microphone Adapter (CT-44).TNCSPGNDGND2 kΩ10 FMICMICEARPTTCT-44MIC/SPAfter connecting the TNC to the transceiver, set the output signal level to the TNC byadjusting the sound volume level of your transceiver.Also, adjust the signal level input to your transceiver using the output level adjustmentvolume on the TNC (Input level cannot be adjusted on your transceiver).When sending a vast volume of data, the transmission takes a longer time and the transceivermay be overheated.If the transmission is continued for a long time, the overheat prevention circuit will operate andthe transmission power decreases. If the transmission is continued further, the transmissionwill be automatically stopped to prevent the transceiver from overheating and consequentlymalfunctioning.If the overheat prevention circuit has operated and then the transceiver returns to the receivemode, turn the transceiver off, or leave it in the receive mode until the temperature falls.z Set the receive battery Save Function to “OFF” during packet communication by selecting [48RX SAVE] ( 39) in the Set mode.z Reception can be interfered with by noise generated from your PC.If the transceiver enters an abnormal receive state, disconnect the transceiver from the PC,and reconnect it to the PC using a photo coupler device or noise filter.z For details on how to connect TNC to the PC, refer to the TNC instruction manual.
