1.0 Good Shielding Practices
To retain the RF shielding integrity of the chamber, follow these good shielding
practices:
• Periodically clean and lubricate doors.
• When mounting screw-retaining items within the enclosure, do not
penetrate through both shields of a modular panel system. Screws
must not penetrate any portion of the screen system.
• Do not use framing screws to fasten items within the enclosure.
• When a hole is bored for a new penetration, remove all burrs. Clean
the perimeter of the hole and the penetration with a cleaning agent
before installing the new penetration.
• Nothing must penetrate the enclosure wall, floor, or ceiling without use
of a proper ETS-Lindgren designated penetration.
• Bolts fitted to the modular and pan-type rooms must be fitted to
correctly-sized holes, correctly de-burred, and cleaned.
• Use flat washers on both sides of the shield penetration.

2.0 Maintenance
Before performing any maintenance, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
If you have any questions concerning maintenance, contact ETS-Lindgren
Customer Service.
Optional Maintenance Program
ETS-Lindgren offers an optional maintenance program that consists of a
complete package of services for continued RF integrity in the shielded
enclosures. The services may be performed on a three-month or six-month cycle.
The program consists of the following:
• Inspection of doors and access panels. Extreme care will be taken
to repair, clean, and lubricate the RF seals (fingers and vinyl seals). If
necessary, they will be replaced.
• Inspection of hinges. Hinges will be checked for alignment and
adjusted as needed.
• Inspection of door and access panel latching mechanisms.
Latching mechanism of doors and access panels will be inspected.
Any defective or worn components which cannot be repaired will be
replaced. Adjustment will be performed as needed. Extra material used
to replace damaged parts due to abuse or failure to comply with
recommended maintenance procedures will be charged to the
customer.
• Inspection of tuners. Tuner operation will be checked, lubricated, and
adjusted as necessary.

Tuners
The SMART™ (Statistical Mode Averaging Reverberation Test Site) chamber
tuners are manufactured from rigid structure of gatorboard covered with copper
sheet on the Z-fold section to provide the necessary reflective surface, or of an
aluminum frame with aluminum reinforced sheet reflectors.
No maintenance of the box structure is required in normal use. However, the
surfaces may be dusted or vacuumed periodically to maintain their appearance.
The tuners are supported at their ends only with coupling clamps. These should
be inspected monthly for signs of wear, loose screws, or distortion.
The motors mounted external to the chamber are fixed to the chamber
wall and additionally supported either on a separate frame or the
chamber supports. The motor shaft passes into the chamber through
a shielded penetration fitted to the chamber wall. The horizontal
penetration also ensures that the axial load is not transmitted to the
motor from the tuner.
The RF feed through bearing assembly on the motor side and a self-aligning (on
large chambers) idler bearing on the non-driven end supports the horizontal
tuner. The self-aligning bearing assemblies have a grease nipple that should be
topped off every six months using standard bearing grease. They should also be
checked periodically to ensure free movement and that fixings remain secure.
The tuner body needs only periodic cleaning to remove any accumulated dust.
On all chambers the RF feed-through assembly on the motor side of the tuner
contains a large number of ball bearings. These provide the RF shielding of the
gear shaft as it passes through the shield and should not be removed.
On the SMART 1000 model the tuners are much smaller and subject to less
wear. The tuners should be inspected every six months for signs of excessive
noise or motor overheating. The tuners are lubricated at the factory, so additional
lubrication should not be required.
10 | Maintenance
CLEANING
Removal of the tuner assembly must be
performed by qualified ETS-Lindgren
personnel.
• Remove excess dust from the tuner and bearing assembly with a dry
cloth or vacuum.
• Check the fixings to the shielded room and the tuner assemblies.
Doors
Periodically clean the brass or steel door frame and beryllium copper finger stock
with Channel Master® 9101 lubricant. See the decal applied to the door for more
detailed instructions. If staining or corrosion is present on the brass frame or
finger stock, polish lightly with 3M Scotch-Brite® pads. If extreme staining or
corrosion persists, call ETS-Lindgren for assistance.
Periodically inspect the roller cams and cam blocks to verify that a thin film of
lubricant is present. If additional lubricant is required, apply a very thin film of
silicone grease. The door maintenance kit included with each door contains the
necessary lubricants, cleaning material, and replacement finger stock.
Maintenance | 11
Do not polish the brass or beryllium copper
finger stock with steel wool, electric sanders,
wire brushes, medium or fine sandpaper, or any
abrasive materials or devices other than those
specified in Maintenance on page 40.
Do not polish any of the brass striking surfaces
with any type of brass polish.
Do not apply a floor wax to the door sill of door
types D and E (flush sills). Use caution when
waxing the floors inside and outside the
enclosure to make sure that wax is not applied
to the flush door saddle.
Do not apply wax to the metal surfaces of the
chamber.
Do not attempt to oil hinges or door handles.
They are permanently lubricated.
MONTHLY MAINTENANCE
To catch excess fluids, place absorbent material (cloth, sponge, and so on)
beneath the entire length of the door sill prior to cleaning and lubricating. Do not
wipe finger stock.
Perform proper cleaning and lubrication of the contact finger
mechanism every month.
Use the cleaning agent Channel Master 9101; lubricate only in accordance with
the manufacturer instructions.
1. Use a generous amount of the cleaning agent to flush the entire finger
recess on the door frame. Start across the top of the door frame and
work down both sides. Flush bottom last. This process will wash off all
visible residues on fingers.
2. Wipe brass door frame with a clean cloth.
12 | Maintenance
3. Inspect finger stock; install new finger stock where necessary.
4. Wipe knob edge on door leaf with a clean cloth wetted with cleaning
agent.
ANNUAL MAINTENANCE
1. Perform maintenance as described in Monthly Maintenance (see
previous section).
2. During inspection of finger stock, count the number of patches that
have been replaced. If more than five patches have been replaced,
remove all finger stock (part# 81D-6L) and vinyl seal shield
(part# VS-100) from the channel. Install new finger stock and new seal.
3. Lubricate tuner bearing grease nipples using standard bearing grease.
4. Check motor supply and signal cable condition external to the
chamber.
5. Remove excess dust from motor (and amplifier, if fitted).
REPLACING FINGER STOCK AND VINYL SEAL
1. Remove old finger stock and vinyl seal using needle-nose pliers.
2. Clean channel.
Use the cleaning agent as described in the manufacturer instructions.
3. Cut exact lengths of finger stock for each of the four sides of the frame.
4. Cut exact length of vinyl seal.
5. Starting in upper left corner, install first row of finger stock down the
entire side of the frame.
6. Lubricate fingers and channel again.
7. Again starting in the upper left corner, insert second row of finger stock
down the entire side of the frame. Fingers should be gently pressed
into position one at a time until they are locked in place.
8. Repeat steps 5, 6, and 7 for each of the remaining three sides of the
frame.
Maintenance | 13
9. Re-lubricate all finger stock and channel.
10. Beginning in the middle of the side of the frame, start installing the
vinyl seal by inserting it by hand into the channel opening. Go around
the door frame so that the vinyl seal covers the finger stock completely.
11. Using the right angle corner of a rectangular piece of sheet metal
(about 4 in x 8 in x 16 ga.) or a wide putty knife, gently push the vinyl
seal between the two rows of finger stock to the final position at the
base of the channel. Use caution at the corners to insert the vinyl seal
behind one finger at a time.
12. If fingers are broken during insertion of the vinyl seal, a patch section
must be inserted.
FINGER STOCK REPAIR
For All Doors
You can replace recessed finger stock without removing the door.
Finger stock 81D-6L can be replaced in sections if a maximum of 10 inches is
damaged.
1. Remove broken or loose pieces with needle-nose pliers.
2. Select an overlapping piece not less than four inches longer than the
missing section and insert new finger stock.
For Door Type D and Type E
