• What have been programmed from a PC are stored in memory even after the
TNC unit is removed from the transceiver.
• This TNC unit is not equipped with all the functions an external TNC may have
(Some functions may be limited).
IMPORTANT: • Packet communication is easy to be affected by transmission and re-
ception environment and especially in 9600bps packet mode, commu-
nication error may easily occur unless all segments of S-meter are dis-
played.
• While in packet mode or geolocating communication mode, tones or
codes are not output even if Tone setting or DCS setting is programmed.
