NOTES FOR GOOD COMMUNICATION 1 . The GMRS-1200CH 15 channels are shared on a ‘take turns’ basis. This means other groups may be talking on any of the channels. A common code of ethics/courtesy is to switch to another vacant channel and not to attempt to talk over someone who is already using the channel you first selected. - Page 18 Warning • Do not operate the transceiver unless you are licensed to do so. • Remove the batteries from the transceiver if it is not expected to be used for long periods. This will eliminate the possibility of chemicals leaking from the batteries and corroding the transceiver.
