Weather channels

There are 10 weather channels. Used for monitoring weather channels from the NOAA (National Oceanographic and At- mospheric Administration) broadcasts.

The transceiver can detect a weather alert tone on the se- lected weather channel while receiving the channel, during standby on a regular channel or while scanning. See “Weather alert” on p. 31.

■Microphone lock function

The microphone lock function electrically locks the [Y]/[Z] and [HI/LO] switches on the supplied microphone. This pre- vents accidental channel changes and accidental function ac- cess.

➥While pushing [HI/LO] on the supplied microphone, turn power ON to toggle the lock function ON and OFF.
