SETUP / OPERATION

1. The amplifier is supplied from the factory with the passive reverse
module installed. For active reverse, see installation on next page.

2. The amplifier has a forward bandwidth of 54-860 MHz with a maximum
of 40 dB gain.

3. The optimal input level for proper amplifier operation and to meet
specifications is 0 to 20 dBmV.

4. The optimal output level for proper amplifier operation and to meet
specifications is 30 to 46 dBmV.

5. The optimal levels for return path is input 3-18 dBmV, and output 20-35
dBmV* (*when reverse amplifier option is used).

6. The input slope control is used to equalize the input signal.

7. The gain control is used to adjust the output level of the amplifier.

8. The second slope control is used to adjust the slope or tilt of the output
of the amplifier.

9. The reverse slope and gain control perform the same functions on the
return path when the reverse amplifier module is utilized.

INSTALLATION OF ACTIVE REVERSE MODULE TDA-RA84

1. Unplug amplifiers and remove input & output cables and terminators on
test points.

2. Remove the 8 Phillips head screws holding front cover on.

3. Loosen the 10 Phillips head screws holding the end covers on and lift
off front cover.

4. Remove all 3 / 8-32 nuts and washers on the F ports.

5. Remove the loosened Phillips head screws holding the left end cover on
and remove cover.

6. Unplug the power cable connecting the forward amplifier module to the
power supply P.C. board.

7. Gently lift out the two amplifier modules from the housing.

8. Separate the two modules and set the passive reverse module aside.

9. Carefully line up the connectors on the amplifier module with the
connectors on the reverse amp module and press the two modules
together.

10. Reinstall the modules back in the housing reversing the procedure used
for removing. (Note: Be Sure to Plug in the Amplifier Module Power
Cord).

11. Tighten down all screws and nuts with a screwdriver and wrench.

12. Install reverse amplifier label (supplied with reverse amp module) on
front cover, lining up the holes in the label with the holes in the cover.

be of sufficient magnitude to
constitute a risk of electrical shock
to persons.

TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE

COVER FROM THIS UNIT. NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL THIS

UNIT IS FOR INDOOR USE ONLY.

WARNING:

OR MOISTURE.

TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN

NOTE TO CATV SYSTEM INSTALLER

This reminder is provided to call the CATV System Installer’s attention to Article
820-40 of the NEC that provides guidelines for proper grounding and, in
particular, specifies that the cable ground shall be connected to the grounding
system of the building, as close to the point of cable entry as practical.

IMPORTANT SAFEGUARDS

Read all instructions prior to installation and use.

Retain Instructions – The safety and operating instructions should be retained for
future reference.

1. Heed Warnings – All warnings on the amplifier and in the operating
instructions should be adhered to.

2. Follow Instructions – All operating and use instruction should be
followed.

3. Water and Moisture – Do not use near water – for example, in a wet
basement, or near a swimming pool, and the like. This product is
designed for indoor use only. Do not expose this product to rain or
moisture.

4. Mounting and Ventilation – Proper mounting to a suitable surface
utilizing the mounting holes in the bottom flange of the amplifier is
essential to insure proper operation and prevent damage! Under no
circumstances should the amplifier be supported or suspended from its
AC power cord or the input and output coaxial cables. Whenever

6

possible, the amplifier should be mounted with the cooling fins in a
vertical position to ensure proper heat dissipation. Slots and openings n
the housing are provided for ventilation. To ensure reliable operation of

3

the product and protect it from overheating, these openings must not be
blocked or covered. This product should not be placed in a built-in
installation such as a cabinet or rack unless proper ventilation is
provided.

5. Proper Operation – To insure proper operation, the amplifier should be
adjusted to within its proper operating range as per the amplifier
specifications. Failure to do so may result in improper operation and
product failure.

13. Outdoor Antenna Grounding – If an outside antenna or cable system
is connected to the amplifier, be sure the antenna or cable system is
grounded so as to provide some protection against voltage surges and
built-up static charges. Section 810 of the National Electrical Code,
ANSI / NAPA No. 70-1984, provides information with respect to proper
grounding of the mast and supporting structure, grounding of the lead-in
wire to an antenna discharge unit, size of grounding conductors,
location of antenna-discharge unit, connection to grounding electrodes,
and requirements for the grounding electrode.

6. Fusing – The amplifier contains an external fuse (5x20mm, 0.35A,
250V) and an internal fuse (5x20mm, 1.0A, 250V) for protection.
Should the amplifier fail to operate, unplug the unit, check the external
fuse, or remove the front cover and check the internal fuse. Note, only

replace fuse with the correct size fuse. Failure to do so may create
a risk of fire or a hazardous situation.

7. Grounding or Polarization – This amplifier is equipped with a 3-wire
grounding-type plug, a plug having a third (grounding) pin, the plug will
only fit into a grounding-type power outlet. This is a safety feature. If
you are unable to insert the plug into the outlet, contact your electrician
to replace your obsolete outlet. Do not defeat the safety purpose of the
grounding-type plug.

8. Power-Cord Protection – Power supply cords should be routed so that
they are not likely to be walked on or pinched by items placed upon or
against them, paying particular attention to cords at plugs, convenience
receptacles, and the point where they exit from the appliance.

9. Overloading – Do not overload wall outlets as this can result in a risk of
fire or electric shock.

10. Object and Liquid Entry – Never push objects of any kind into this
amplifier through openings as they may touch dangerous voltage points
or short-out parts that could result in a fire or electric shock. Never spill
liquid of any kind on the amplifier.

11. Power Lines – An outside antenna system should not be located in the
vicinity of overhead power lines or other electric light or power circuits.
When installing an outside antenna system, extreme care should be
taken to keep from touching such power lines or circuits as contact with
them might be fatal.

12. Servicing – Do not attempt to service this amplifier yourself as opening
or removing covers may expose you to dangerous voltage or other
hazards. Refer all servicing to qualified service personnel. Repair or
other replacement should be returned to TONER. (969 Horsham Road,
Horsham, Pennsylvania 19044 USA).
