Front and Rear RF Boards and Front and Rear Rod Driver Boards
 To replace the front and rear radio frequency (RF) boards and front and rear rod drive
boards.
1. Shut down your system by following the steps in “Shutting Down the TSQ 9000 System”
on page 127 .
2. Slide the top cover panel toward the back of the instrument and lift it off.
3. The front RF board is the second board standing on end toward the center of the
instrument. The rear RF board is the third board standing on end toward the center of
the TSQ 9000 instrument. Use a T20 Torxhead screwdriver to remove the screw holding
the board and bracket to the chassis.
4. Locating the RF Boards and Brackets
Note See the ISQ and TSQ GC-MS Spare Parts Guide for information about ordering an
RF board. This board must be replaced by a Field Service Engineer, so when you place an
order for a new board, schedule the Field Service Engineer as well.
Note
You do not have to remove the ion source cartridge or column or vent the system. If
you are using hydrogen as a carrier gas, power off the GC.
Note The steps to remove and replace the front and rear RF boards are the same. Refer to
the images for the proper location of each board.
CAUTION - INSTRUMENT DAMAGE Limit handling of the boards as much as possible.
Do not touch any board components. Hold the board by the sheet metal bracket only.
