Manual frequency selection mode
The operation of the GC-W900-IM can be restricted to a specific channel within the 900 MHz band
by setting DIP switches 1-8 on the access point as shown in Table 1-Channel Selection. The
subscriber unit responds to the access point's choice of channel and its DIP switches have no effect
and do not need to be selected.
