141Functions Used As NeededSet ModeUsing the transceiver for packet communicationYou can perform packet communication with your transceiver by connecting TNC(Terminal Node Controller) using an optional connection cable (CT-44).TNCSPGNDGND2 kΩ10 FǴMICMICEARPTTAfter TNC is connected, set the level of output to TNC by adjusting the sound volumelevel of your transceiver.Also adjust the level of input to your transceiver using the output level adjustmentvolume on the TNC (Input level cannot be adjusted on your transceiver)Caution When sending a vast volume of data, the transmission takes a longer time and the transceiver maybe overheated.If the transmission is continued for a long time, the overheat prevention circuit will operate and thetransmission power decreases. If the transmission is continued further, the transmission will beautomatically stopped to prevent the transceiver from overheating and consequently malfunctioning.The transceiver will return to the receive mode.When the transceiver returns to the receive mode after the overheat prevention circuit has operated,turn the transceiver off, or keep it in the receive mode until the temperature cools.Tips• Set the Receive Battery Save function to OFF during packet communication by selecting[8 CONFIG] [17 SAVE RX] in the Set mode.• The reception can be interfered with a noise generated from PC.If the transceiver can not receive normally, disconnect it from the PC and reconnect it to the PCusing a photocoupler or noise filter.• To connect the TNC and PC, refer to the TNC instruction manual.
