	meter values.
RT	Sets or reads RIT (OFF/ON).
RU	Raises RIT frequency.
RX	Selects receive mode.
SC	Sets or reads Scan (OFF/ON).
SD	Sets or reads Semi Break-in delay time.
SM	S-meter and TX RF meter readings
SQ	Sets or reads squelch level.
SR	Resets the transceiver.
TX	Selects transmit mode.
UP	MIC UP function
VD	Sets or reads VOX delay time.
VR	Triggers the Voice Synthesizer for
	message output.
VX	Sets VOX (OFF/ON).
XT	Sets or reads XIT (OFF/ON).

ERROR MESSAGES

In addition to the Answer Command, the transceiver can send the following error messages:

Error	Reason for Error
Message
?;	• Command syntax was incorrect.
	• Command was not executed due to
	the current status of the transceiver
	(even though the command syntax
	was correct).
	Note: Occasionally this message may not
	appear due to microprocessor transients in the
	transceiver.
E;	A communication error occurred such
	as an overrun or framing error during a
	serial data transmission.
O;	Receive data was sent but processing
	was not completed.

COMMAND USE PRECAUTIONS

1Do not use the control characters 00 to 1Fh since they are either ignored or cause a Ò?Ó answer.

2Program execution may be delayed while turning the Tuning control rapidly.

3Receive data is not processed if the frequency is entered from the keypad.
