NOTES FOR GOOD COMMUNICATION

1 . The FR-1538 14 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.

2.The FR-1538 has been designed to maximize performance and improve transmission range in the field. To avoid interference, it is recommended that you do not use the units closer than 5 feet apart.

3.For best transmission results, always keep your mouth about 2-3 inches from the microphone (10) and speak slowly in a normal voice.
