Audible User Feedback Tones - Kenwood TK-980 Service Manual

TK-980/981
• ACK Delay Time
ACK Delay Time is the amount of time from the end of
receiving a data to the beginning of sending an
acknowledgement. It should be adjusted as the repeater's
hang-up delay time. Also, it must be set less than the Maxi-
mum ACK Wait Time of the calling radio unit.
• TX Delay Time (RX Capture)
TX Delay Time is the amount of unmodulated transmis-
sion to let the called unit stop scanning or exit its battery
save mode. It is used only when starting a data communica-
tion sequence.
• Data TX Modulation Delay Time
Data TX Modulation Delay Time is the amount of time
from the beginning of transmission to the beginning of a
data modulation. It is used every time data is transmitted.
It must be set to more than 300ms if data communication is
made in Trunking Mode.

Intercept Tone
This tone indicates that the transceiver is out of range. It
indicates that the PTT button is pressed, and transmission
has started, but the repeater cannot be connected and talk-

200ms intervals.)
Delay Tone
This tone is output when the PTT button is pressed and
the repeater is accessed three times or more to indicate
connection with the repeater is delayed. This tone is the
