2.8.2 Go to Receive Frequency
Description On receipt of this command, the radio checks the format and does a range
check on the frequency. If it is valid, the radio sends an ACK response and
then initialises the synthesizer with the new frequency. One should allow
20ms for the synthesizer to settle at the new frequency. If the command is
invalid, a NAK response will be sent and the receiver will remain at the last
selected frequency. If the radio is transmitting then a NAK response will also
be sent.
Command Rssxxxxxxxxxcc
Where:
Effect This command has immediate effect with the receiver retuning to this
channel. If the synthesizer is out of lock then a NAK response will be sent.
2.8.3 Load Transmit Frequency
Description On receipt of this command, the radio checks the format and does a range
check on the frequency. If it is valid, the radio sends an ACK response. If the
command is invalid, a NAK response will be sent and the transmit frequency
will not change. If the radio is transmitting then a NAK response will also
be sent.
