Parts Reference
The following parts and hardware are included with this installation kit (hardware not shown):
Tools Required
Phillips screwdriver (not provided), 1/8'' and 5/32'' [4mm] hex wrenches (provided), 1/2'' socket wrench (provided).
WARNING!
The VHM Arm contains a strong spring which is used to counterbalance the weight of the mounted
device. The Arm housing should never be disassembled by non-GCX personnel. Additionally, the
mounted device should only be removed with the Arm in its highest vertical position, with the Height
Locking Lever in the fully locked position. Failure to follow these guidelines could result in serious injury.
Before mounting the Arm:
1. Note that this arm has a wide range of motion both up/down and side to side. Please consider carefully the device
being mounted and the proximity of the assembly to other equipment, hospital personnel, and the patient. GCX
recommends that the hospital’s risk management personnel verify the appropriateness of the application prior to
installation and use.
2. If assistance is needed regarding an application, please contact a GCX product specialist at [phone].

Attaching the Philips-supplied Table Top Mount to the Mounting Adapter
Installation Note: Do not attach the Table Top Mount to the Arm/Mounting
Adapter if you will be mounting an MP20/30 monitor with the mounting
interface shown in photo (right). See "Mounting the Monitor" (page 3) for
instructions specific to this type of mounting interface.
1. Fasten Philips-supplied Table Top Mount to Mounting Adapter with one (1) M6 x 12mm FHMS and two (2) M6 x 8mm
FHMS (see below).
Mounting VHM Arm in Wall Channel
1. Thread the Height Locking Lever into the mounting hole in the right side of the
Arm. The Lever operates by turning clockwise to tighten or counterclockwise to
loosen. Ensure that the Locking Lever is in the locked position before mounting
the Arm in the channel.

Counterbalance Adjustment
The VHM Arm must be adjusted to counterbalance the mounted instrument throughout the Arm’s vertical range of motion.
When properly counterbalanced, the VHM Arm will maintain its height without engagement of the Height Locking Lever or
Locking Knob. Because instrument weights vary, adjustment will typically be required to achieve optimal performance. A
1/2" [13mm] socket wrench is provided for this critical adjustment.
To adjust counterbalance:
1. Grasp the Arm behind the mounted instrument(s) and carefully move the Arm to a horizontal position that allows
access to the Adjuster Cover (below left). Lock Arm in horizontal position.
2. Open the Adjuster Cover by inserting a flat blade screwdriver in the slot at the rear of the Cover and prying upward. If
necessary unlock and readjust the Arm until the Counterbalance Adjuster bolt is accessible through the Adjuster Cover
(below center). Lock Arm when Counterbalance Adjuster is accessible.
3. With the 1/2" [13mm] socket wrench on the Adjuster, carefully unlock the arm. Turn the Adjuster counterclockwise
(CCW) to increase counterbalance force, or clockwise (CW) to decrease counterbalance force. Counterbalance is
correctly adjusted when the mounted instrument can be moved up or down with minimal force and does not rise or fall
after releasing the Arm.
4. Close the Adjuster Cover.
WARNING: Do not attempt counterbalance adjustment unless the instrument and accessories are
mounted on the Arm. Use caution while

Cable Guides (2)
Cable Management
Two (2) Molded Cable Guides are provided to facilitate routing of cables along the
underside of the arm. Squeeze the Cable Guide until its edges snap into the
grooves in the bottom surface of the arm. Leave extra cable loose at the front and
rear of the arm to prevent cable binding or damage to connectors.
Installing the 16'' Wall Channel Cover
Install the Wall Channel Cover in accordance with the Channel Cover Installation Guide (DU-UT-0001-20).
VHM Arm Operation & Adjustment
Swiveling the Mounted Instrument and Adjusting Swivel Tension
1. To swivel mounted instrument, simply push or pull instrument.
2. To adjust swivel tension, tighten or loosen the Swivel Tension
Nut using the 1/2'' [13 mm] socket wrench provided.
Installation Note: It may be necessary to remove an existing
down post from the swivel cup to gain access to the Swivel
Tension Nut.
Tilting the Mounted Instrument and Adjusting Tilt Tension
1. To tilt the instrument, grasp the top and bottom of the instrument and tilt it to
the desired angle.
2. To adjust tilt tension, equally tighten or loosen the two (2) Tilt Tension screws
using the 5/32'' hex wrench provided.
Pivoting the Arm and Adjusting Pivot Tension
1. To pivot Arm at Channel, simply push on side of Arm.
2. To adjust pivot tension, remove top and bottom plastic
bolt caps from Pivot Bolt. Using the 1/2" [13mm] socket wrench
provided and a 1/2'' [13mm] box or open-end wrench, tighten or
loosen Pivot Bolt and Hex Nut to desired tension. Reinstall bolt
caps back over each end of Pivot Bolt.

WARNING
• Do not attempt to adjust height without instrument being mounted on Arm.
• Use caution when disengaging the Height Locking Lever. The total mounted load may have
changed due to the addition or removal of equipment (other than primary instrument) while
the Height Locking Lever was engaged. A change in the total load can cause a sudden
downward or upward movement of the Arm when the Height Locking Lever is disengaged.
Adjusting Height of the Mounted Instrument
1. Grasp mounted instrument on sides (or handle) and move to desired height. When Arm is counterbalanced correctly
(page 4), it will maintain position when adjusted to a new height. Note: Disengagement/re-engagement of the Height
Locking Lever may be necessary during vertical adjustment of mounted instrument (see WARNING above).
Engagement of the Height Locking Lever is not required during normal operation of the counterbalanced instrument.
Positioning VHM Arm in Channel
1. Lock the Arm position using the Height Locking Lever.
2. Using the 1/8'' hex wrench provided, loosen four (4) set screws in Slide.
3. Relieve the weight of the mounted instrument by lifting against the underside of the
Arm, near the instrument. Simultaneously, push up or pull down the opposite end of
the Arm immediately in front of the Slide.
4. Tighten four (4) set screws.
Use caution when disengaging the Height Locking
Lever. The total mounted load may have changed
due to the addition or removal of equipment (other
than primary instrument) while the Height Locking
Lever was engaged. A change in the total load can
cause a sudden downward or upward movement
of the Arm when the Height Locking Lever is
disengaged.
Instrument Must Be Mounted

Periodic Maintenance
Periodically check all tilting, swiveling, pivoting, and mounting hardware. Tighten as necessary for optimal operation and
safety.
Cleaning the Mounting Assembly
1. The mounting assembly may be cleaned with most mild, non-abrasive solutions commonly used in the hospital
environment (e.g. diluted bleach, ammonia, or alcohol solutions).
2. The surface finish will be permanently damaged by strong chemicals and solvents such as acetone and
trichloroethylene.
3. Do not use steel wool or other abrasive material to clean the mounting assembly.
4. Damage caused by the use of unapproved substances or processes will not be covered by warranty. We recommend
testing of any cleaning solution on a small area of the arm that is not visible to verify compatibility.
5. Do not submerge or allow liquids to enter the arm. Wipe any cleaning agents off of the arm immediately using a water-
dampened cloth. Dry the arm thoroughly after cleaning.
CAUTION: GCX makes no claims regarding the efficacy of the listed chemicals or processes as a means for controlling
infection. Consult your hospital’s infection control officer or epidemiologist. To clean or sterilize mounted instruments or
accessory equipment, refer to the specific instructions delivered with those products.
