FAQ#
Turn Fast Acquisition mode on/off.
#
represents a one character number
to turn the Fast Acquisition mode on or off. Where 0 = off, and 1 = on.
The fast acquisition mode permits cycling between stored channels
within the memory of the receiver using the remote bus to step channels.
The facility makes use of the standard recall facilities within the receiver,
but enables them to be done faster than otherwise possible.
The speed is made possible by preventing certain display operations
during recall. The display reverts to a
“Fast
Acquisition”
display using
minimum graphics when in remote. Only the channel and frequency are
updated to the display with a special fast format.
When enabled, the receiver will not accept commands to change
operating mode, bandwidth, AGC on/off, AGC decay, or MGC setting.
Sweep and scan modes may not be entered. If any of these commands
are sent, a command not allowed fault will be generated.
