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.
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.
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.

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.
