Audible User Feedback Tones - Kenwood TK-880 Service Manual

TK-880/H
• 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.
