Functions to Use as Necessary

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).
MIC/SP
After connecting the TNC to the transceiver, set the output signal level to the TNC by
adjusting the sound volume level of your 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 and then the transceiver returns to the receive
mode, turn the transceiver off, or leave it in the receive mode until the temperature falls.

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.
