Using the Transceiver for Packet Communication
You can perform packet communication with your transceiver by connecting a TNC (Ter-
minal Node Controller) using an optional Microphone Adapter (CT-44).

After connecting the TNC to the transceiver, set the output signal level to the TNC by
adjusting the sound volume level of the transceiver.
Also, adjust the signal level input to your transceiver using the output level adjustment
volume 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
transceiver may be overheated. If the transmission is continued for a long time, the
overheat prevention circuit will operate and the transmission power decreases. If the
transmission is continued further, the transmission will be automatically stopped to
prevent the transceiver from overheating and consequently malfunctioning. If the overheat
prevention circuit has operated the transceiver returns to the receive mode, turn the
transceiver OFF, or leave it in the receive mode until the temperature falls.
• Set the receive battery Save Function to OFF during packet communication by pressing
and holding the [

• Reception can be interfered with by noise generated by the Personal Computer.
• 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.
• For details on how to connect a TNC to the PC, refer to the TNC instruction manual.
