Features: |
Model
CM-7775 UHF Amplifier - Gain 26dB
Model CM-7777 UHF/VHF Amplifier - Gain
26dB UHF, 23dB VHF
Model CM-7778 UHF/VHF
Amplifier - Gain 23dB UHF, 16dB VHF
All models feature 75 Ohm inputs and outputs.
All models use Model 0747 117VAC Indoor Power Supply.
Models
CM-7777 and
CM-7778 feature
a switchable FM trap. It is factory set "in".
Models
CM-7777 and
CM-7778 may be configured
for either a single UHF/VHF input or separate UHF and VHF inputs. It is
factory set to "single UHF/VHF input". |

OUTDOOR
AMPLIFIER INSTALLATION |
|
1. Ensure correct setting of FM trap (Models
CM-7777 and
CM-7778). Ensure
correct setting of VHF input (Models
CM-7777
and
CM-7778). To
change either of the above, see Figure 1. |
| |
 |
| |
|
2. To
install 75 Ohm coaxial cable, first determine the proper length of cable
required between the antenna and the pre-amplifier; also between the power
supply (Fig 3) and the pre-amplifier. Next, slip a weather boot (provided)
over the cable. Attach male "F" connectors to the cable ends. When the "F"
connectors have been attached, slip the weather boot up over the "F" connector
of the pre-amplifier. If the antenna is 300 Ohms, use a balun, e.g. Channel
Master Model 0090 as shown in Fig. 2. |

NOTICE
TO CATV SYSTEM INSTALLER |
|
This
reminder is provided to call the CATV System Installer's attention to Article
820-40 of the NEC that gives guidelines for grounding. NEC Article 820-40
specifies that the cable ground shall be connected to the grounding system
of the building at a point closest to the cable entry as practical. |
| |
|
3. Using
the U-bolt, flat washers, star-lock washers and hex nuts provided in the
hardware bag, mount the amplifier to the mast as shown in Figure 2. Note:
The amplifier is to be mounted with the connections facing downwards. It
may be mast or wall mounted. |
| |
|
INDOOR
POWER SUPPLY INSTALLATION: |
|
1. Choose
a location for mounting the indoor power supply as close to the television
set and a 120 volt 60 Hz AC electrical outlet as possible. Using the two
screws provided, mount the power supply to the wall or any flat surface.
See Figure 3. |
 |
| |
|
2. Attach
a male "F" connector to the other end of the coaxial cable that has been
run to the indoor power supply location from the outdoor antenna amplifier.
Connect this cable to the connection labeled "FROM ANT' on the power supply. |
|
3. Next,
connect a length of 75 Ohm coaxial cable from the connection labeled "TO
TV" on the power supply to the television set. Note: For television sets
that have separate UHF and VHF terminals-use a Channel Master UHFNHF band
separator to make the proper connections. |
|
4. Finally,
plug the AC cord into the electrical outlet. Note: This is a solid state
unit, no warming up time is required. Current drain is minimal (less than
an electrical shock) so that the unit may remain plugged-in at all times. |
| |
|
CAUTION |
|
To reduce
the risk of electric shock, do not remove cover (or back). No user-serviceable
parts inside. Refer servicing to qualified service personnel. |
|
Presence
of uninsulated "dangerous voltage" within the product's enclosure may be
of sufficient magnitude to constitute risk of electric shock. |
|
The presence
of important operating and maintenance instructions are contained in the
literature accompanying this product. |
|
Caution:
To prevent electric shock, match wide blade of plug to wide slot, fully
insert. |
|
WARNING:
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THE POWER SUPPLY TO RAIN
OR MOISTURE. |
| |
|
FM TRAP
(where applicable) |
|
This
broadband trap is shipped with the switch in the "IN" position, thus eliminating
FM signal. If FM signals are desired, slide the switch to the "out" position.
See Figure 2. |
|
FM interference
is indicated by a "herringbone" pattern appearing on any VHF channel (2
through 13). If this type of interference is present, be sure that the FM
trap switch is in the "IN" position. |
