4. Scan Operating
■ System Scan
System scan can be selected with the “Scan” key by programming the scan feature. When the “Scan” key is
pressed and the “SCN” mark appears, scan mode in entered. Scanning starts from the system following the currently displayed system. When a call is received, scanning
stops, and the system and group are displayed.
When programming key is touched during scanning, the
scan stops and the revert system or group can be changed.
Scanning resumes one second after the key is released.
There are two types of system scan.
• Fix system scan
All the set systems except locked-out ones are scanned.
If the Del/Add feature is assigned to the programmable key,
it can be controlled from the front panel.
5
TK -863G
OPERATING FEATURES
• List type system scan
A scan list can be set for each system.
The list to be scanned can be changed by changing the
display system.
If many systems have been set, the scan speed can be
increased by narrowing the systems to be scanned with
scan lists.
■ System Lockout
The system lockout feature is used to lock systems out
of the scan sequence, and can be selected by programming
in the following two ways;
• Fixed lockout
The system to be locked out is selected by programming.
When a locked system is selected, the Delete (
appears on the left of the SYSTEM indicator. The revert system is scanned even if it is locked out. If there is a locked
system, the Delete (
ning.
) indicator flashes during fixed scan-
) indicator
• User selectable lockout
If the scan lockout feature is programmed to a key, the
user can lock systems out of the scan sequence with the
key. To lock a system out of the scan sequence, press the
key when the system is displayed. The Delete (
is displayed on the left of the SYSTEM indicator.
To unlock a system, select the system and press the key.
The Delete (
tem has returned to the scan sequence. The revert system
is scanned even if it is locked out. If there a locked system,
the Delete (
systems are locked out, the scan stops and only the revert
system is received.
) indicator disappears to indicate that the sys-
) indicator flashes during fixed scanning. If all
) indicator
■ Drop-out Delay Time (Scan Resume Time)
If a call is received during scan, the scan stops. The scan
resume time can be programmed as 0 to 300 seconds in
one-second increments. The default value is 3 seconds.
■ Dwell Time
The dwell time is the time after transmission ends until
the scan resumes in scan mode. It can be set 0 to 300 seconds by programming. The default value is 3 seconds.
■ System/Group Revert
System/group revert can be programmed for one of the
following;
• Last called revert
The system or group changes to the revert system or
group when a call is received with the system or group being scanned.
• Last used revert
If a system/group call is received during scanning and the
PTT button is pressed for transmission and response within
the drop out delay time, the system or group is assigned as
the new revert system or group.
• Selected revert
If the system/group was changed while scanning, the
newly selected system/group.
• Selected + Talkback revert
If the system/group was changed while scanning, the
newly selected system/group. The transceiver “talks back”
on the current receive group.
■ Scan Massage Wait
The time for staying with the home repeater that receives a signal during system scan and monitoring data
messages can be programmed. If there is no signal from
the home repeater, the system is scanned for about 50ms.
If there is a signal, three data messages are monitored.
Normally, three data messages are monitored for each system, and it can be increased in multiples of three data messages per line to up to eight lines.
If the repeater data message indicates that there is no
call, data monitoring is terminated and the home repeater of
the next system is scanned.
■ Group Scan Operation
Group scan can be programmed for each group. In addition to the ID codes of the selected group, the ID codes of
the other groups that are permitted for group scan are decoded. (The two fixed ID and block decode codes are always decoded.)
If, during group scanning, a call is received with one of
the selectable group ID codes for which group scan is enabled, the group display indicates the group number that the
call came in with. That group then becomes the new selected group. Group scan resumes after the specified dropout delay time or dwell time shared by the system scan
elapses.
■ In Conventional System
If QT or DQT is set for the channel, the channels, including signalling, are scanned.
In case of the priority group is set in conventional system, if a group scan (including group scan during a system
scan) temporarily stops (receiving) in a group that does not
have priority, a look back is performed to the priority group.
Look back is performed according to the look back time A
and B settings. If a call is received on the priority group,
reception immediately switches to the priority group.

OPERATING FEATURES
TK -863G
5. Details of Features
■ Time-out Timer
The time-out timer can be programmed in 15 seconds
increments from 15 seconds to ten minutes. If the transmitter is keyed continuously for longer than the programmed
time, the transmitter is disabled and a warning tone sounds
while the PTT button is held down. The alert tone stops
when the PTT button is released.
■ PTT ID
PTT ID provides a DTMF ANI to be sent with every time
PTT (beginning of transmission, end of transmission, or
both).
You can program PTT ID “on” or “off” for each group.
The contents of ID are programmed for each transceiver.
The timing that the transceiver sends ID is programmable.
BOT : DTMF ID (BOT) is sent on beginning of transmis-
sion.
EOT : DTMF ID (EOT) is sent on end of transmission.
Both : DTMF ID (BOT) is sent on beginning of transmis-
sion and DTMF ID (EOT) is sent on end of transmission.
■ Radio Password
When the password is set in the transceiver, user can not
use the transceiver unless enter the correct password.
This code can be up to 6 digits from 0 to 9 and input with
the key, and "SCN" key.
■ Off Hook Decode
If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no
effect for decoding QT/DQT.
■ Horn Alert
Horn alert can be set to on or off for each group. If horn
alert has been set to YES for a group and DEC ID/QT/DQT
matches, the horn alert, HOR. is turned on and off.
Either continuous or non-continuous operation can be set
by the FPU. The horn alert port is enabled or disabled as
follows;
Off hook horn alert
Enable Yes Yes
Disable No Yes
■ Pulse
The horn alert port, HOR, is turned on and off as follows;
0.5s 0.5s 0.5s 0.5s 0.5s
Hook off Hook on
HOR
The timing when the fixed LTR ID matches is as follows
(trunking mode);
1s 0.5s 1s
■ Continuous
Horn alert can be reset by setting an expiration time from
the FPU, pressing the Horn Alert key, or setting off hook.
■ Data TX with QT/DQT
Whether programmed QT/DQT is modulated or not with
a data transmission. A radio unit can receive a data message regardless of QT/DQT if the receiving unit is not scanning.
■ Call Indicator
The call indicator can be programmed for each group. In
trunked system, it can be set to respond to a selectable decode ID or one of two fixed IDs, except block IDs. When a
call is received with a selectable decode ID, the call indicator
flashes. When a call is received with a fixed ID, the call
indicator lights continuously.
On a conventional system, the call indicator can be programmed to light for each QT or DQT code. It keeps flashing while a call is being received. It is turned off by pressing
any front panel key.
■ Free System Ringback
This feature is available only when a telephone interconnected ID code is selected. If a busy tone sounds when the
PTT button is pressed, the transceiver enters this mode automatically.
When the PTT button is released, a beep sounds for
400ms to indicate that the mode has been entered. If the
scan is on, it is resumed (the “SCN” mark goes on). When
any repeater becomes available, a ringing tone sounds and
this mode ends.
The mode is terminated when the system, group, scan,
PTT, key is changed.
■ System Search
This feature can be programmed to automatically access
other programmed systems when the selected system cannot be accessed. If an intercept tone sounds when the PTT
button is pressed after setting the mode, the transceiver
has entered the mode.
If the group ID is a telephone interconnect ID, the transceiver then attempts to access, in succession, other systems that have a telephone interconnect ID in the revert
group location. If the group ID is a dispatch ID, the transceiver attempts to access other systems that have a dispatch ID programmed in the revert group location.
7
TK -863G
OPERATING FEATURES
If there is no system to be accessed, an intercept tone
sounds, the mode is terminated, and the transceiver returns
to the first system. If the access is successful, the mode is
terminated, and the searched system becomes the new selected system (If during scanning, the scan stops).
■ Transpond
This feature can be programmed to turn on and off for
each group. If the ID of the group for which transpond is
enabled is received, two data messages (transmit ID and
turn-off code) are automatically transmitted if the PTT button is not pressed as a response within the time set (0 to
300 seconds in 1-second increments). If the PTT button is
pressed within the time, the transpond is not preformed.
■ Transmit Inhibit
The transceiver can be programmed with a transmit inhibit block of ID codes. If an ID code within this block is
decoded the preset time before the PTT button is pressed,
transmission is inhibited. The BUSY indicator lights and a
busy tone sounds until the PTT button is released to indicate
that transmission is not possible (except clear-to talk mode).
■ ARQ Mode
It affects Trunking mode only. Automatic Repeat
reQuest (ARQ) mode is a manner to minimize the air traffic
of data communication. Also, it enables to occupy the
trunking repeater channel for the data communication period.
6. Audible User Feedback Tones

5. PC Mode
5-1. Preface
The TK-863G transceiver is programmed using a personal
computer, a programming interface (KPG-46) and programming software (KPG-76D).
The programming software can be used with an IBM PC
or compatible. Figure 1 shows the setup of an IBM PC for
programming.
5-2. Connection Procedure
1. Connect the TK-863G to the personal computer with the
interface cable.
2. When the Power is switched on, user mode can be entered immediately. When the PC sends a command, the
radio enters PC mode.
When data is transmitted from transceiver, the red LED
blink.
When data is received by the transceiver, the green LED
blink.
Notes :
• The data stored in the personal computer must match
model type when it is written into the flash memory.
• Change the TK-863G to PC mode, then attach the interface cable.
5-3. KPG-46 Description
(PC programming interface cable : Option)
The KPG-46 is required to interface the TK-863G to the
computer. It has a circuit in its D-subconnector (25-pin) case
that converts the RS-232C logic level to the TTL level.
The KPG-46 connects the modular microphone jack of
the TK-863G to the computers RS-232C serial port.
IBM-PC
KPG-46
5-4. Programming Software Description
The KPG-76D programming disk is supplied in 3-1/2" disk
format. The software on this disk allows a user to program
TK-863G radio via a programming interface cable (KPG-46).
5-5. Programming With IBM PC
If data is transferred to the transceiver from an IBM PC
with the KPG-76D, the destination data (basic radio information) for each set can be modified. Normally, it is not necessary to modify the destination data because their values are
determined automatically when the frequency range (frequency type) is set.
The values should be modified only if necessary. Data
can be programmed into the flash memory in RS-232C format via the modular microphone jack.
6. Firmware Programming Mode
6-1. Preface
Flash memory is mounted on the TK-863G. This allows
the TK-863G to be upgraded when new features are released in the future. (For details on how to obtain the firmware, contact Customer Service.)
6-2. Connection Procedure
Connect the TK-863G to the personal computer (IBM PC
or compatible) with the interface cable (KPG-46). (Connection is the same as in the PC Mode.)
6-3. Programming

7. Clone Mode
Programming data can be transferred from one radio to
another by connecting them via their modular microphone
jacks. The operation is as follows (the transmit radio is the
master and the receive radio is the slave).
1. Turn the master TK-863G power ON with the [
held down. If the password is set to the TK-863G, the
TK-863G displays “CLN LOCK”. If the password is not
set, the TK-863G displays “CLONE”.
2. When “CLN LOCK” is displayed, only the [
[SCN], and [0] to [9] keys can be accepted. When you
enter the correct password, and “CLONE” is displayed,
the TK-863G can be used as the cloning master. The following describes how to enter the password.
3. How to enter the password with the microphone keypad;
If you press a key while “CLN LOCK” is displayed, the
number that was pressed is displayed on the TK-863G.
Each press of the key shifts the display in order to the
left. When you enter the password and press the [SCN]
key, “CLONE” is displayed if the entered password is
correct. If the password is incorrect, “CLN LOCK” is
redisplayed.

6. Audio Mute
When the transceiver is connected to external devices,
you can control the receiving audio signal using the Audio
mute signal of the external device. If you mute the receiving
audio signal using this modification, the transceiver does not
mute the “Audible User Feedback Tones”.
6-1. Transceiver Modification Procedure
Solder the lead of a silicon diode to the base of Q502 on
the TX-RX unit (B/2). If you connect this line to the Audio
Mute signal of the external device using this diode, the audio signal of the receiver can be controlled.
