Safety

Important Safety Instructions

1. Read, keep, and follow all of these instructions; heed all warnings.

2. Do not use this equipment near water, rain or moisture.

3. Use only a dry cloth to clean the equipment.

4. Do not install near any heat source such as a radiator, heat register,

amplifier, or stove.

5. Do not attempt to plug the unit into a two-blade outlet (with only

two prongs of equal width).

IMPORTANT:

By design, these monitors will only plug into a three-prong outlet for
your safety. If the plug does not fit into your outlet, contact an
electrician to replace the obsolete outlet.

6. Protect the power cord from being walked on or pinched,

particularly at plug’s source on the equipment and at the socket.

7. Use only the attachments/accessories specified by the

manufacturer.

8. Unplug the equipment during lightning storms or when unused

for long periods of time.

9. Use of a cart is neither recommended nor approved by Wohler.

10. Refer all servicing to qualified service personnel. Servicing will be

required under all of the following conditions:

• The equipment has been damaged in any way, such as when

the power-supply cord or plug is damaged.

• Objects have fallen onto the equipment; or the equipment has

been exposed to rain or moisture, or liquid has been spilled
onto the equipment.

• The equipment does not operate normally.

• The equipment has been dropped.

Safety Symbols

RMT-173 Series

In s t a lla t i o n R e c om m e n da t i o n s

WARNING:

The symbol to the left warns of electric shock hazard inside the unit.
Disconnect the power cord before removing access panels when
installing upgrades. Only qualified service personnel are to operate the
equipment with covers removed, and are to exercise caution to avoid
personal injury.

Installation Recommendations

Heat Dissipation

The ambient temperature around the unit should not exceed 40°
Celsius (104° Fahrenheit). Allow plenty of space around the unit for air
circulation.

Mounting/Bracing

A table top (-TT) stand or rack mount (-RM) kit may be provided. A
standard VESA 100 mounting hole pattern is provided on the back of
the unit for use with other mounts (not supplied).

Refer to Mounting on page 5 for instructions on attaching the desktop
stand.

Connections and Cable Recommendations

We recommend that you limit the length of the cables that you use for
feeding HD-SDI signals sources to the HD-SDI inputs of the RMT-173
Series units and that you use a Belden 1694A cable (or equivalent). The
HD-SDI inputs (IN1 and IN2) can be up to 150 meters (492 feet) in
length for 1.5 Gbps (HD), more for 270 Mbps (SD) and less for 3Gbps.

Note:

HDMI 1.3 or 1.4 cable lengths of 2m (6 feet) are guaranteed
to work well. Four meters (12 feet) lengths of high quality
cable should work well enough, but is not guaranteed for all
situations. Longer HDMI cables often degrade signal
quality. Active extender transmitter/receiver pairs can be
used to cover long distances.

Electrical Interference

Be careful to properly terminate/ground signals and avoid
mismatched cable types and other similar causes of undesired
reflections in digital signal systems. If severe enough, such reflections
can result in corruption of the digital data stream. As with any audio
equipment, maximum immunity from electrical interference requires
the use of shielded cable. The internal circuitry ground is connected to
the chassis.

Power

The unit comes with a standard 12 VDC/5 A external power adapter
and connects an A/C mains power source (65W, 100 to 240 VAC, 50/
60Hz) through the IEC connector provided on the power adapter.

When the mains plug or appliance coupler is used as the disconnect
device, the disconnect device connection should remain accessible to be
operable.

Unpacking and Installation

Contents

While unpacking the components, verify that none of the components
are damaged. The selected stand or mounting kit comes in a separate
box.

Also verify that the box contains all of the following:
