Sharp A260 - UX B/W Thermal Transfer, Service Manual

UX-A260U

2 – 18

SW-I3 No. 3 Two way record function

If this switch is set to "1", the machine disables two way recording.

SW-I3 No. 4 Toll saver

Used to turn on the toll saver function. If it is off, the reception frequency
in the AM mode is the same as in the FAX mode.

SW-I3 No. 5 ~ No. 7 Reserved

Set to "0".

SW-I3 No. 8 Transfer dial recall

If this switch is set to "1", machine disables redial in Transfer function.

SW-I4 No. 1 ~ No. 4 AGC maximum gain (Line)
(10 ~ 25dB) (1dB step)

The AGC Maximum Gain limits the gain applied by the AGC. Messages
with average energy below the AGC Energy Reference Level will have
their average energy level increased by no more than the AGC Maximum
Gain. The AGC Maximum Gain should average energy of the message
with the lowest average energy to the AGC Energy Reference Level.

SW-I4 No. 5 ~ No. 8 AGC maximum gain (Mic)
(10 ~ 25dB) (1dB step)

The AGC Maximum Gain limits the gain applied by the AGC. Messages
with average energy below the AGC Energy Reference Level will have
their average energy level increased by no more than the AGC Maximum
Gain. The AGC Maximum Gain should average energy of the message
with the lowest average energy to the AGC Energy Reference Level.

SW-I5 No. 1 ~ No. 4 AGC energy reference level access code (Line)
(-0 ~ -30dB) (2dB step)

The AGC Energy Reference Level controls the playback level. Any
message having average speech energy above the energy reference
level has its playback level attenuated, and any level has its playback
level increased. If the playback level is too high (low), then decreasing
(increasing) the AGC Energy Reference Level will achieve the desired
level.

SW-I5 No. 5 ~ No. 8 AGC energy reference level access code (Mic)
(-0 ~ -30dB) (2dB step)

The AGC Energy Reference Level controls the playback level. Any
message having average speech energy above the energy reference
level has its playback level attenuated, and any level has its playback
level increased. If the playback level is too high (low), then decreasing
(increasing) the AGC Energy Reference Level will achieve the desired
level.

SW-I6 No. 1 ~ No. 4 AGC gain adaptation threshold (Line)

The AGC adjusts the amount of gain applied to the incoming message
only when the average energy exceeds the AGC Gain Adaptation
Threshold. The AGC Gain Adaptation Threshold prevents message
background noise from corrupting the gain provided that the AGC Gain
Adaptation Threshold is greater than the background noise energy. In
the event that a message has background noise energy greater than
the AGC Gain Adaptation Threshold, the AGC Gain can be no greater
than the AGC Maximum Gain. Note that the AGC Gain Adaptation
Threshold must always be greater than the RPACS VOX Turn-On
Threshold.

SW-I6 No. 5 ~ No. 8 AGC gain adaptation threshold (Mic)

The AGC adjusts the amount of gain applied to the incoming message
only when the average energy exceeds the AGC Gain Adaptation
Threshold. The AGC Gain Adaptation Threshold prevents message
background noise from corrupting the gain provided that the AGC Gain
Adaptation Threshold is greater than the background noise energy. In
the event that a message has background noise energy greater than
the AGC Gain Adaptation Threshold, the AGC Gain can be no greater
than the AGC Maximum Gain. Note that the AGC Gain Adaptation
Threshold must always be greater than the RPACS VOX Turn-On
Threshold.

SW-I7 No. 1, No. 2 AGC slew rate (Line)

The AGC Slew Rate controls the convergence of the message playback
level to the desired playback level. A large slew rate will allow faster
convergence and a small slew rate will allow slower convergence.

SW-H1 No. 5 Busy tone detect continuation sound detect during
OGM

Used to detect the continuous tone of specific frequency during OGM
output.

SW-H1 No. 6 Busy tone detect continuation sound detect
Used to select detection of the continuous sound of certain frequency.

SW-H1 No. 7 Busy tone detect intermittent sound detect during
OGM

Used to detect the intermittent tone of specific frequency during OGM
output.

SW-H1 No. 8 Busy tone detect intermittent sound detect
Used to select detection of the intermittent sound of certain frequency.

SW-H2 No. 1, No. 2 Busy tone detection pulse number

Used to set detection of Busy tone intermittent sounds.

SW-H2 No. 3 Fax switching when A.M. full

If the answering machine’s memory is full and there is no response, the
machine automatically switches to Fax reception.

SW-H2 No. 4 Busy tone detect continuation sound detect frequency

Set detecting frequency of busy tone continuation sound for 320 ~ 570
Hz of 320 ~ 460 Hz.

SW-H2 No. 5, No. 6 Reserved

Set to "0".

SW-H2 No. 7 AM OGM announce only mode

If this switch is set to 1, the machine will not record ICM.
(disconnect the line after OGM output)

SW-H2 No. 8 Busy tone continuous sound detect time

Set detecting time busy tone continuous sound for 5 or 10 seconds.

SW-I1 No. 1, No. 2 ICM recording time

Used to select the incoming message recording time to 15sec/30sec/
60sec/4min.

SW-I1 No. 3, No. 4 A.M. quiet time 1

Used to select four kinds of no sound time (2 sec ~ 5 sec) after reception
in the T.A.D mode until OGM is output.

SW-I1 No. 5, No. 6 A.M. quiet time 2

Used to select four kinds of no sound time (0 sec ~ 3 sec) after OGM
output the T.A.D mode until ICM recording is started.

SW-I1 No. 7 Key input buzzer on/off switch (Two way recording mode)

Used to turn ON/OFF key input buzzer in the TWO-WAY recording mode.

SW-I1 No. 8 CPC signal detection

Used to turn ON/OFF the CPC (Calling Party Control) signal detection.

SW-I2 No. 1 ~ No. 5 A.M. quiet detect time

Used to set no sound time (0 sec ~ 32 sec) during the T.A.D. mode
operation.

SW-I2 No. 6 ~ No. 8 CPC detection time

Used to set the CPC (Calling Party Control) signal detect time.

SW-I3 No. 1 Reserved

Set to "0".
