OPERATING FEATURES
3-17. "TOT" (Time-Out Timer)
The transceiver has the "TOT". This parameter selects
the period of time users can continuously transmit.
When the selected period passes, the transceiver gener-
ates an warning tone and stops the transmission.
3-18. "TOT" Pre-Alert
The transceiver has "TOT" pre-alert timer. This parameter
selects the time at which the transceiver generates "TOT"
pre-alert tone before "TOT" is expired.
"TOT" will be expired when the selected time passes
from a TOT pre-alert tone.
3-19. "TOT" Re-Key Time
The transceiver has "TOT" re-key timer. This timer is the
time you can not transmit after "TOT" exceeded. After "TOT"
re-key time expired you can transmit again.
3-20. "TOT" Reset Time
The transceiver has "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
PTT is released unless the "TOT" reset timer has expired.
3-21. Signalling
Signalling "AND/OR" sets the audio unmute condition for
any channel programmed with the option signalling (2-Tone/
DTMF).
AND : "AND" requires both the valid option signalling and
the programmed QT/DQT to be received for audio to
unmute (and initiate an option signalling decode alert).
OR : "OR" requires either the valid option signalling or the
programmed QT/DQT to be received for audio to unmute
(an option signalling decode alert is only initiated if the
proper option signalling is decoded).
3-22. Noise Canceling Microphone
Reduce the background noise.
4. Channel Features
You can use these features using the programming soft-
ware (KPG-59D).
4-1. Alphanumeric Display (Channel Name)
The programming software (KPG-59D) enables you to set
the alphanumeric display for channel name. The total text
size of channel name are 7-digits.
For example, If you set 2-digits for group name, then you
can use 5-digits for channel name. The characters can be
used as shown in Figure 1.

4-2. Option Signalling
The transceiver is programmable to the option signalling
(2-Tone decode program 1, 2-Tone decode program 2, 2-
Tone decode program 3, DTMF decode) to each channel. It
is useful to receive an individual call.
Receive format is selectable "AND" or "OR" with QT/DQT.
The radio response of option signalling is programmable call
Alert and "Transpond" for each option signalling (2-Tone de-
code program 1, 2-Tone decode program 2, 2-Tone decode
program 3, DTMF).
4-3. PTT ID
PTT ID provides a DTMF ANI to be sent with every time
PTT (connect ID at beginning of transmission, disconnect ID
at end of transmission, or both).
You can program PTT ID "on" or "off" for each channel.
The contents of ID are programmed for each transceiver.
4-4. Busy Channel Lockout
Transmission is inhibited when the channel is busy. It is
able to set this feature "Yes" or "No" for each channel.
4-5. Beat Shift
This is the feature that the microprocessor shifts its sys-
tem clock frequency slightly to prevent the receive interfer-
ence. This transceiver can program this feature "Yes" or "No"
for each channel.
