I purchased this manual to repair my Teac set and with the support of this manual I rectified the problem.
Excellent service manual, i didn't believe i could find it for such old product, it is very explanatory, managed to fix the disk player!!!
Nice manual. Clear copy and very rare, to boot. Great price, too!
Excellent service manual. Complete service info. with schematics, step-by-step instructions and illustrations. Well worth the price!
Great product, helped me to restore vintage walkman cassette.
Just some pictures could be little bit more sharp and contrast
The transceiver is capable of having ID. The format is DTMF. The timing that the transceiver sends the ID is programmable. Begin of TX ID (BOT) : Begin of TX ID is sent at the beginning of transmission. End of TX ID (EOT) : End of TX ID is sent at the end of transmission. Both : Begin of TX ID is sent at the beginning of transmission and End of TX ID is sent at the end of transmission. There is also a "PTT ID" setting for each channel.
6. Option Signalling (DTMF/2 tone)
Built-in DTMF decoder is available for option signalling. Built-in 2-Tone decoder is available for option signalling. It is possible to use individual call, group call, DBD (Dead Beat Disable). Note : DBD is only DTMF Preset operation is triggered when there is a match with Option Signaling. When Option Signaling matches on a Group Channel where it is set to Yes, the Option Signaling display flashes and Option Signaling is canceled. Settings after this will cause "Transpond" or "Alert" to sound. Setting the Selective Call Alert LED will cause the LED to start flashing orange. Mute or Unmute is triggered by the ID/QT/DQT/Carrier when option signaling matches (when Option Signal is deactivated by a transmission).
3) Battery Warning
This transceiver has a battery warning feature. If low voltage is detected during transmission, the transceiver warns you by a flashing red "LED". When the voltage is detected to be even lower during transmission, the transceiver stops transmission and warns you by a flashing red "LED" and a beep. Please notice "indication" for the battery exchange, charging time by flashing red LED and beep.
Option Signaling match conditions can be selected with AND/OR logic. Alert/Transpond Triggers at match with QT/ DQT/ID+DTMF(2tone);Opt Triggers at match with DTMF(2tone);Opt AF Mute Open Triggers at match with QT/ DQT/ID+DTMF(2tone);Opt Triggers only for match with QT/DQT/ID;Signaling
4) "TOT" Pre-Alert
The transceiver has a "TOT" pre-alert timer. This parameter selects the time at which the transceiver generates a "TOT" pre-alert tone before the "TOT" is expired. "TOT" will expire when the selected time passes from the TOT pre-alert tone.
5) "TOT" Re-Key Time
The transceiver has a "TOT" re-key timer. This timer is the time you cannot transmit after the "TOT" is exceeded. After the "TOT" re-key time expires you can transmit again.
6) "TOT" Reset Time
The transceiver has a "TOT" reset timer. This timer is the minimum wait time allowed during a transmission that will reset the "TOT" count. "TOT" reset time causes the "TOT" to continue even after the PTT is released, unless the "TOT" reset timer has expired.
Even if set as OR, there is no Alert/Transpond just with DTMF. Even if set as OR, AF mute cannot be canceled just by a match with DTMF. In conventional channels not set with QT/DQT, signaling is a match just by receiving the carrier.
When Option Signaling matches on a Group channel where it is set to Yes, Option Signaling is canceled when it matches a group channel set to Yes. After Option Signaling matches, Option Signaling can automatically Reset after a specified time. Dead Beat Disable When the D.B.D (Dead Beat Disable) code matches, a preset operation is performed. When D.B.D matches on all group channels regardless of whether Option Signaling = Yes/No, then TX Inhibit or TX RX Inhibit is activated by the settings performed afterwards. D.B.D is canceled when the D.B.D. code + "#" is received. Transpond is always activated when the D.B.D code matches. Alert is not output. An Option Signaling match is not displayed.
7) OST (Operator Selectable Tone)
The transceiver is capable of having the "OST" function and 16 tone pairs (QT/DQT) with a max 10-digit name for each tone pair.
8) Clear to Transpond
The transceiver waits for an acknowledment signal until the channel free. This feature ensures the acknowledment signal is receive by another party.
9) Battery Save
This is the automatic battery saver during standby mode operation. The receiver circuit is turned on and off to conserve the battery life. 6
