Notes:
When recording in handsfree (half-duplex) mode using the built-in
speakerphone, the record warning tone may not be audible to the
far-end party.
The transmit recording level is lower than the receiving voice level
for intercom calls; the transmit recording level for CO calls is
normal.
Depending on the recording device(s), separate cables may be
required for the warning tone and speech path. In this case,
connect the warning tone cables to input terminals T1 and T2 on
the ADA-U Unit. (T3 and T4 are used as the tape recorder input.)
When remote control of the recorder is necessary, the record
start/stop control is provided by connecting to T5 (or T7) and T6
on the ADA-U Unit. (Connecting to T5 or T7 is determined by the
specifications of the recorder.)
When a warning Tone is provided from the recording equipment, it
should be input via T3 and T4 on ADA-U Unit. Do not use T1 and
T2 to input Beep Tone.
Conversations cannot be recorded from terminals connected to
an APR/APA-U Unit. Speakerphone calls through the HFU-U Unit
cannot be recorded.
