Channel Enable List

•Tap on the Channel Enable List button to display a dialog box listing available channels.

This dialog box is completed by default with all channels that have frequencies configured. A checkmark indicates that a channel is enabled. An unchecked check box indicates that the channel is disabled. The maximum number of channels supported by the RA1001 Narrow Band radio is 20.

Enabling a channel allows the channel to be set to an operating channel (Channel Number) and makes it available for channel searching. For example, if Channel 1 is the operating channel and all other channels are enabled, the 7530 G2 can roam through all 20 channels.

Channel Switch Speed

This parameter changes the threshold the 7530 G2 uses to determine when communication quality with a base station is unacceptable. When this threshold is exceeded, the unit starts channel searching for a new base station.

Setting this parameter to “Slow” means a higher threshold – the 7530 G2 is more tolerant of poor communication quality. When the channel quality of the hand-held radio drops below 46%, the unit monitors the channel quality for 15 timeout periods before searching for a new channel. If Channel Switch Speed is set to “Fast”, the current channel is only monitored for up to 2 time-out periods before channel switching begins.

Important: “Fast” switch speed is most effective where coverage areas are largely overlapping. If the coverage areas barely overlap, have dead spots, or if the 7530 G2 frequently operates on the fringe of coverage, this parameter should be set to “Slow”.
