Quick Recall of a Tuning Band’s Assigned Frequencies
Each Tuning Band’s assigned receiver channel frequencies are stored and automatically recalled when selecting a Tuning
Band. This is particularly useful for:
a)
Quickly comparing the RF performance of assigned frequency groups as you switch between tuning bands.
b)
Pre-configuring alternate tuning bands with pre-assigned frequencies to prepare for unforeseen changes in the
RF environment.
Note:
Each Tuning Band’s assigned frequency cache is cleared when Nexus is powered down.
