Mt Whitney Zone Forums General Discussion Four Female Hikers Missing 20 Miles Northeast of Huntington

If you send an SOS message on a SPOT and want to cancel it, you have to press SOS and hold it until the SOS light blinks red to send a “Cancel SOS” message. Leave SPOT on until the SOS light stops blinking red to make sure your message got out. Turning off a SPOT or sending “Check-in/OK” won’t send anything to the authorities.
