Operating Instnidlons

Description

Ihe Bogen Model CPT-ID is a compact, integrated unit consist
ing of a stereo/mono cassette tape player and an FM-stereo/FM/AM
tuner. It provides a reliable, economical source of background music
for a sound system. Program continuity is assured by the automatic
tape reverse feature, which changes the direction when the tape

reaches the limit of its travel.

The CPT-ID operates on 120 volts AC. It incorporates a low­Icvcl, low-iinpcdanoe output, which will drive the aui^iy input of
a public address amplifier. The unit can also drive 8-ohm loud

speakers directly with its internal stereo amplifier (five watts per
channel).

If desired, the CPT-ID may be mounted in a standard 19-inch,,
equipment radt by means of the optional RPK55C Rack Panel Kit.

Controls and Functions

1. ON VOL & TONE — Power on/off switch and Time control.
Clockwise rotation of TONE increases treble response;
counterclockwise rotation increases bass response.

2. EJ — Eject cassette tape. Press IN to eject cassette.

3. AUTO REVERSE CASSETTE — Insert cassette until it en
gages; unit automatically goes from radio to tape playing mode.
PROG — Fast Forward (left button) & Rewind (right button)

4.

Selectors. Pressing both buttons simultaneoudy changes direc

tion of tape travel.

TUNE & BAL — Rotate TUNE control in either direction to

5.

select desired frequency. Rotate BAL control clockwise to in
crease sound to the right channel; counterclockwise to increase
sound to the left channel.

TAPE DIRECTION INDICATORS — Shows direction of the

tape.

IMPORTANT MAINTENANCE INFORMATION ON PAGE 2

7. MO/ST — For normal FM-stereo reception set this switch to the
IN position. The ST indicator will illuminate for a stereo signal.
Set the switch in the OUT position for monaural operation, or
when receiving weak signals that cause the ST indicator light to
go on and off.

3. DX/LO — Distant or weak FM station signals are boosted when
this switch is in the DX position. LO indicator illuminates when

the switch is in the LOcat position.

9. FREQUENCY SCALE—Scale indicates radio fi^uency being

received.

10. AM/FM SELECTOR

To Play A Cassette Tape

The door ol the CFX -Ш is hinged and will open and close with

the insertion and removal of the cassette.

1. Rotate the ON/VOL switch clockwise and increase the volume
slightly.

2. Check the cassette to be certain that the tape is tightly wound on
the reels.

3. Insert the narrow end of the cassette into tape door, with exposed
tape toward the right. When the cassette is fully inserted it will
automatically begin to play (the unit will switch from radio to the
tape player mode).

4. When the tape reaches the limit of its travel, the CPT-ID will
automatically reverse direction and play the opposite side of the
tape.

a. Tb advance tape rapidly, press the left PROG button.
b. lb rewind tape rapidly, press the right PROG button.

5. TO remove the cassette, press the eject button.

Important Note

Always remove the cassette from the CPT-ID after use to
prevent damage to the cassette and tape drive mechanism.

FM/AM Operation

1. Rotate the power SW VOL switch clockwise and increase volume
slightly.

2. Select either FM or AM radio band by pressing the appropriate
AM or FM selector button.

3. Select desired position of the Stereo/Mono mode switch.

4. Rotate tuning knob to locate the desired radio frequency as

indicated on the frequency scale.

FM Line Antenna. The CPT-ID line cord may be used as an

internal FM Line Antenna for receiving FM broadcasts (See Figure

1). For improved reception, particularly in weak signal areas or for
tuners mounted in consoles or racks, installation of an outdoor FM
or “T” antenna is necessary.

Important Rojtine Maintenance

To avoid the need for frequent servicing, we strongly recom

mend periodic cleaning of the tape head, capstans, and pinch
rollers. This will also ensure high quality reproduction of

programmed material. The unit should be cleaned after every 20 to
30 hours of operation. A high-qua lity cassette cleaning cartridge can

be used, however, if one is not readily available, proceed as follows:

1. Saturate a cotton swab with isopropyl alcohol.

2. While holding the cassette door open, locate the tape head (to the
right of the opening and toward the center of the unit).

3. Clean the tape head, capstans, and pinch rollers with the cotton

swab.

4. Allow parts to dry before operating the unit.

Overload Protection

The CPT-ID is protected by an internal 100mA, slow blow fuse.
If this fuse opens, the unit will shut down completely; have the
trouble investigated by a qualified technician.

Caution

There are no user-serviceable parts within the unit. To avoid

an electric shock hazard, have all internal servicing per

formed by qualified service personnel only. The warranty

will become void if repairs are made by other than the Bogen
Service Department or authorized service agency.

important Antenna Information

Articles 810 and 820 of the National Electric Code, ANSI/NFPA
No. 70-1978 provides information regarding antenna grounding.
The CPT-ID is designed for connection to various antenna systems
as illustrated in Figures 1 through 3.

Caution

Use No. 8 A WG aluminum wire, or larger, as ground wires

for both mast and lead-in and secure to building structure

with insulators spaced 4 to 6 feet apart. Mount antenna
discharge unit as closely as possible to where the lead-in
enters the building structure.

External FM Antenna. If installing a standard 300-ohm antenna

system, connect the twin-lead transmission line as shown in Figure

2. If conditions require use of a coaxial transmission line, such as
RG-11 or RG-59, connect as shown in Figure 3. Always disconnect

the FM line antenna when using exiemal FM antenna.
