Safety Instructions (European)
Notice For U.K. Customers If Your Unit Is Equipped With A Power Cord.
WARNING: THIS APPLIANCE MUST BE EARTHED.
The cores in the mains lead are coloured in accordance with the following code:
GREEN and YELLOW - Earth BLUE - Neutral BROWN - Live
As colours of the cores in the mains lead of this appliance may not correspond with the coloured markings identifying the terminals in your plug, pro-
ceed as follows:
The core which is coloured green and yellow must be connected to the terminal in the plug marked with the letter E, or with the earth symbol, or col-
oured green, or green and yellow.
The core which is coloured blue must be connected to the terminal marked N or coloured black.
The core which is coloured brown must be connected to the terminal marked L or coloured red.
The power cord is terminated in a CEE7/7 plug (Continental Europe). The green/yellow wire is connected directly to the unit's chassis. If you need to
change the plug and if you are qualified to do so, refer to the table below.
WARNING: If the ground is defeated, certain fault conditions in the unit or in the system to which it is connected can result in full line voltage between
chassis and earth ground. Severe injury or death can then result if the chassis and earth ground are touched simultaneously.

Manual
The Operating Manual contains instructions to verify the proper operation of this unit and initialization of certain options.
You will find these operations are most conveniently performed on the bench before you install the unit in the rack.
Please review the Manual, especially the installation section, before unpacking the unit.
Trial Period Precautions
If your unit has been provided on a trial basis:
You should observe the following precautions to avoid reconditioning charges in case you later wish to return the unit to
your dealer.
(1) Note the packing technique and save all packing materials. It is not wise to ship in other than the factory carton. (Re-
placements cost $35.00).
(2) Avoid scratching the paint or plating. Set the unit on soft, clean surfaces.
(3) Do not cut the grounding pin from the line cord.
(4) Use care and proper tools in removing and tightening screws to avoid burring the heads.
(5) Use the nylon-washered rack screws supplied, if possible, to avoid damaging the panel. Support the unit when tighten-
ing the screws so that the threads do not scrape the paint inside the slotted holes.
Packing
When you pack the unit for shipping:
(1) Tighten all screws on any barrier strip(s) so the screws do not fall out from vibration.
(2) Wrap the unit in its original plastic bag to avoid abrading the paint.
(3) Seal the inner and outer cartons with tape.
If you are returning the unit permanently (for credit), be sure to enclose:
The Manual(s)
The Registration / Warranty Card
The Line Cord
All Miscellaneous Hardware (including the Rack Screws and Keys)
The Extender Card (if applicable)
The Monitor Rolloff Filter(s) (OPTIMOD-AM only)
The COAX Connecting Cable (OPTIMOD-FM and OPTIMOD-TV only)
Your dealer may charge you for any missing items.
If you are returning a unit for repair, do not enclose any of the above items.
Further advice on proper packing and shipping is included in the Manual (see Table of Contents).
Trouble
If you have problems with installation or operation:
(1) Check everything you have done so far against the instructions in the Manual. The information contained therein is
based on our years of experience with OPTIMOD and broadcast stations.
(2) Check the other sections of the Manual (consult the Table of Contents and Index) to see if there might be some sug-
gestions regarding your problem.

WARNING
This equipment generates, uses, and can radiate radio-frequency energy. If it is not installed
and used as directed by this manual, it may cause interference to radio communication. This
equipment complies with the limits for a Class A computing device, as specified by FCC
Rules, Part 15, subject J, which are designed to provide reasonable protection against such
interference when this type of equipment is operated in a commercial environment. Operation
of this equipment in a residential area is likely to cause interference. If it does, the user will be
required to eliminate the interference at the user’s expense.
I
WARNING
This digital apparatus does not exceed the Class A limits for radio noise emissions from digi-
tal apparatus set out in the radio Interference Regulations of the Canadian Department of
Communications. (Le present appareil numerique n’emet pas de bruits radioelectriques de-
passant les limites applicables aux appareils numeriques [de las class A] prescrites dans le
Reglement sur le brouillage radioelectrique edicte par le ministere des Communications du
Canada.)

IMPORTANT
Perform the installation under static control conditions. Simply walking across a rug can gen-
erate a static charge of 20,000 volts. This is the spark or shock you may have felt when
touching a doorknob or some other conductive surface. A much smaller static discharge is
likely to destroy one or more of the CMOS semiconductors employed in OPTIMOD-FM. Static
damage will not be covered under warranty.
There are many common sources of static. Most involve some type of friction between two
dissimilar materials. Some examples are combing your hair, sliding across a seat cover or
rolling a cart across the floor. Since the threshold of human perception for a static discharge
is 3000 volts, you will not even notice many damaging discharges.
Basic damage prevention consists of minimizing generation, discharging any accumulated
static charge on your body or workstation, and preventing that discharge from being sent to or
through an electronic component. You should use a static grounding strap (grounded through
a protective resistor) and a static safe workbench with a conductive surface. This will prevent
any buildup of damaging static.
