Your system might cause TV or radio
interference even when it is operating
properly. To determine whether your
system is causing the interference,
turn off your system. If the interfer-
ence goes away, your system is caus-
ing the interference. Try to eliminate
the interference by:

• Moving your system away from

the receiver

• Connecting your system to an out-

let that is on a different electrical
circuit from the receiver

• Contacting your local RadioShack

store for help

If you cannot eliminate the interfer-
ence, the FCC requires that you stop
using your system. 

Dirt, dust or particles of the tape’s
coating can accumulate on the tape
heads and other parts that the tape
touches. This can greatly reduce the
performance of the System 740. Use
the following cleaning procedure after
every 20 hours of tape player opera-
tion.

1. Disconnect power.

2. Open the cassette compartment

doors on TAPE 1 and TAPE 2.

3. Press 

 on TAPE 1 and TAPE

2 to expose the tape-handling
parts.

4. Use a cotton swab dipped in

denatured alcohol or tape head
cleaning solution to clean the
record/play heads, pinch rollers,
capstans, tape guides, and erase
head.

5. When you finish cleaning, press

 on TAPE 1 and

TAPE 2, close the cassette com-
partment doors, and reconnect
power.

Your local RadioShack store sells a
complete line of cassette deck clean-
ing supplies.
