RECORDING PROCEDURE

This Spot Announcing Machine stops tape motion by sensing the unrecorded sound section on the tape. Announcements may be commenced overriding the background music by detecting the recorded level.

To ensure that your desired message is announced without fail, we suggest you keep records of the

message numbers and their contents when recording. During recording, the recorded signals are sent out to

the external amplifier. To prevent this, insert the headphone into the headphone jack and no signal is

transmitted to the amplifier.

1.Connect the microphone to the microphone input, set the microphone switch to ON and switch the power on.

2. Load the tape after confirming that the auto switch

is placed in the manual mode.

Note : Be sure to confirm that the tape is provided with erasure prevention tabs.

3.Depress the REC SPACE button. The tape begins travelling and stops in about 7 seconds after producing the unrecorded sound section on the tape. The SPACE LED flashes (the RUN LED also illuminates) during tape travel and illuminates when the tape motion stops.

4.Depress the REC RUN button. The RUN LED illuminates (the SPACE LED also illuminates) and the tape begins to travel to permit recording.

(Do not make a break of longer than 4 seconds during recording.)

5.Depress the REC SPACE button after recording. The tape begins travelling and stops in about 7 seconds after producing the unrecorded sound section on the tape. The SPACE LED flashes (the RUN LED also illuminates) during tape travel and illuminates when the tape motion stops.

6.Repeat the procedure of Item steps 4 through 5 for further recording. After all messages have been recorded, make more than three unrecorded sound sections on the tape by depressing the REC SPACE button three times. (This is necessary for automatic tape rewinding.)

7.Depress the stop button to release the recording mode.

The built-in AGC circuit keeps recording level constant. When using the microphone of very low sensitivity,

the recording level becomes low. In this event, recording should be made with the mouth closer to the

microphone, or replace the microphone by one with higher sensitivity.
