Aninadvertentorintentional“keyandhold”actionwithoutanyvoicecommunicationwillnot
disablethechannelbecauseofthisfeature.Thetime‐outdurationcanbeupsetfrom1second
to99seconds1secondintervals.Thetime‐outdurationcanbedisabledbysettingitto00,
whendisabled,thechannelwillkeycontinuouslywiththepresenceofareceivedsignal.
