ClearScan™
ClearScan™ performs a frequency scan of the factory-defined
and any set-up user-programmable groups in order to find the
group with the highest number of clear receive channels. After
about 20-30 seconds, the group with the highest number of clear
receive channels will be displayed. The next best group and so
forth may be accessed with the [DOWN] and [UP] arrow
buttons.
• Press and hold [MENU] + [SET] for three seconds to enter
ClearScan™. The base station will now start searching all
groups for the ones with the greatest number of receiver
channels clear of interference.
• ClearScan™ will display the group that has the most
interference free receive channels. These clear channels are
displayed on the right half of the screen. Press [SET] to
place the base station on this group and return to the
operating screen. The first four receive channels displayed
will be the ones set for the group. The [UP]/[DOWN]
buttons may be used to select the next best group and so
forth.
To achieve the best results quickly when using ClearScan™,
please complete the following for setting up a sing BTR-800
system:
• Turn off all wireless intercom and wireless microphone
equipment.
• Turn on all wireless microphones and wireless monitor
transmitters. Make sure that this equipment is distributed at
least 3 to 5 feet apart from each other to minimize any
frequency intermodulation effects.
• Turn on one TR-700/800/825 and perform the ClearScan
function as described on
page 55 and page 66 of this
manual.
• When the first result is displayed on the TR, write this down
along with the next 6 or 7 results. This number represents
the specific BTR transmitter that should provide the best
results for operation. This is referred to as the Group.
• Once you have recorded the first 6 or 7 results from the TR,
turn off the TR unit.
• Turn on the BTR-700 or BTR-800 and perform the
ClearScan function as described above. The results of the
BTR will provide the number of Channels or TR
transmitters that can operate in a given group.
• Since you have already established the best BTR Group
(base station transmit frequency) to operate on, selection of
the operating channels is now much easier.
• Simply match the number of TRs to operate on your system
with the first and best Group number that you have
recorded.
• When you have scrolled to the appropriate Group number
that displays the number of beltpacks to be used on the
system, simply press [SET] on the BTR to place the BTR on
the selected Group and Channel.
• Finally, go back to the TRs and program to the appropriate
Group and Channel.
