values when the device is turned on.
The user may recall the Alarm Volume--OFF setting by using Setup mode to turn on the device and
selecting

returns to the default if it is set below 85% even when the device is
turned on with Setup mode.
Alarm settings are retained and available for recall for approximately 30 seconds after removing
