groups.

2) Scan Start Condition

One or more non-priority channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off).

When you activate the key programmed to the scan function, scan starts. The scan icon ("SCN") lights and "SCAN" is indicated on display.

TK-260G/270G

OPERATING FEATURES

3) Scan Stop Condition

The scan stops temporarily if the following conditions are satisfied. 1 The receiving signal matches the signalling code in your

radio that is set by the programming software (KPG-56D).

2 When the Monitor key is depressed.

4) Scan Channel Types

1 Priority channel is the most important channel for scan,

and always detects a signal during scan and when the scan stops temporarily.

2 Non-priority channels detect a signal during scan. For the

channels that can be selected with the group or channel selector when the scan does not occur, the "A" icon lights.

5) Priority Channel Setting

A priority channel can be set as follows with the programming software (KPG-56D).

1 Specify a priority channel as a fixed priority channel. 2 Make a selected channel a priority channel.

Specify the initial channel before the operator changes it.

6) Scan Type According to the Priority Channel

1 When no priority channel is set : Only the non-priority

channels are scanned.

If a non-priority channel stops temporarily, it stops until

there is no signal on the channel.

2 When priority channel is set : Either priority channel is

scanned.

If a non-priority channel stops temporarily, a priority channel

signal is detected at certain intervals.

If a priority channel stops temporarily, it stops until there is

no signal on the priority channel.

6 Selected with talkback

The transceiver reverts to the channel before scanning or

the channel that you changed during scan.

8) Scan End

When you reactivate the key programmed to the scan

function during scan mode, scan ends.

The scan icon ("SCN") and "SCAN" or revert channel

(programmable) display goes off.

9) Temporarily Delete/Add

It is possible to delete or add a channel temporarily during scan. When scan stops on an unnecessary channel, for example by interference of the other party, press the delete/ add key, then that channel is deleted temporarily and scan will re-start immediately.

When you would like to add a deleted channel temporarily to the scan sequence, select the desired (deleted) channel during scan, and press the delete/add key before scan re-starts.

That channel is added temporarily to the scan sequence. The temporarily deleted or added channels are returned to their pre-set delete/add conditions when the transceiver exits from scan mode.

5. Details of Features

1) Time-out timer

The time-out timer can be programmed in 15 seconds increments from 15 seconds to 300. 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.

7) Revert Channel

The revert channel is used to transmit during scanning and set by the programming software (KPG-56D). 1 Priority

The transceiver reverts to the priority channel.

2 Priority with talkback

The transceiver reverts to the priority channel.

If you press PTT during a resume timer (dropout delay time, TX dwell time) or calling, you can transmit on the current channel to answer to the call however revert channel is set to priority channel.

After resume time, scan re-starts and the transmission channel returns to the priority channel.

3 Selected channel

The transceiver reverts to the channel before scanning or the channel that you changed during scan.

4 Last called channel

The transceiver reverts to the last called channel during scan.

5 Last used channel

The transceiver reverts to the last used (transmitted) channel during scan. "Last used" revert channel includes

talkback function.

2) Selective Call Alert LED

You can select whether or not the LED on the transceiver

flashes orange when selective call has occurred.

3) PTT ID

PTT ID provides a DTMF ANI to be sent with the PTT button every time it is used (Begin of TX ID at beginning of transmission, End of TX ID at end of transmission, or both).

You can program the PTT ID as one of the followings.

Off, BOT (Begin of TX ID), EOT (End of PTT ID), BOTH.

The contents of ID are programmed for each channel.

The transceiver is capable of having ID. The format is DTMF.

The timing that the transceiver sends the ID is programmable.

Begin of TX ID (BOT) : Begin of TX ID is sent at the

beginning of transmission.

End of TX ID (EOT) : End of TX ID is sent at the end of

transmission.

Both : Begin of TX ID is sent at the beginning of transmission

and End of TX ID is sent at the end of transmission.

There is also a "PTT ID" setting for each channel.

TK-260G/270G

OPERATING FEATURES

4) Battery Warning

This transceiver has a battery warning feature. If low voltage is detected during transmission, the transceiver warns you by a flashing red "LED".

When the voltage is detected to be even lower during transmission, the transceiver stops transmission and warns you by a flashing red "LED" and a beep.

Please notice "indication" for the battery exchange, charging time by flashing red LED and beep.

5) "TOT" Pre-Alert

The transceiver has a "TOT" pre-alert timer. This parameter selects the time at which the transceiver generates a "TOT" pre-alert tone before the "TOT" is expired.

"TOT" will expire when the selected time passes from the TOT pre-alert tone.

6) "TOT" Re-Key Time

The transceiver has a "TOT" re-key timer. This timer is the time you cannot transmit after the "TOT" is exceeded. After the "TOT" re-key time expires you can transmit again.

7) "TOT" Reset Time

The transceiver has a "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 the PTT is released, unless the "TOT" reset timer has expired.

6. Option Signalling (DTMF/2 tone)

Built-in DTMF decoder is available for option signalling. Built-in 2-Tone decoder is available for option signalling.

It is possible to use individual call, group call, DBD (Dead

Beat Disable). Note : DBD is only DTMF

Preset operation is triggered when there is a match with

Option Signaling.

When Option Signaling matches on a Group Channel where it is set to Yes, the Option Signaling display flashes and Option Signaling is canceled. Settings after this will cause "Transpond" or "Alert" to sound.

Setting the Selective Call Alert LED will cause the LED to start flashing orange.

Mute or Unmute is triggered by the ID/QT/DQT/Carrier when option signaling matches (when Option Signal is deactivated by a transmission).

AND/OR

Option Signaling match conditions can be selected with AND/OR logic.

8) OST (Operator Selectable Tone) (TK-270G K types only)

The transceiver is capable of having the "OST" function

and 16 tone pairs (QT/DQT) with a max 10-digit name for each tone pair.

9) Clear to Transpond

The transceiver waits for an acknowledment signal until the

channel free.

This feature ensures the acknowledment signal is receive

by another party.

10) Battery Save

This is the automatic battery saver during standby mode

operation. The receiver circuit is turned on and off to conserve the battery life.

Even if set as OR, there is no Alert/Transpond just with

DTMF.

Even if set as OR, AF mute cannot be canceled just by a

match with DTMF.

In conventional channels not set with QT/DQT, signaling is

a match just by receiving the carrier.

Auto Reset

When Option Signaling matches on a Group channel where it is set to Yes, Option Signaling is canceled when it matches a group channel set to Yes.

After Option Signaling matches, Option Signaling can automatically Reset after a specified time.

Dead Beat Disable

When the D.B.D (Dead Beat Disable) code matches, a preset operation is performed.

When D.B.D matches on all group channels regardless of whether Option Signaling = Yes/No, then TX Inhibit or TX RX Inhibit is activated by the settings performed afterwards. D.B.D is canceled when the D.B.D. code + "#" is received.

Transpond is always activated when the D.B.D code matches. Alert is not output. An Option Signaling match is not displayed.

5-1. Preface

The TK-260G/270G transceiver is programmed using a personal computer, a programming interface (KPG-22) and programming software (KPG-56D).

The programming software can be used with an IBM PC or compatible. Figure 1 shows the setup of an IBM PC for programming.

TK-260G/270G

Fig. 1

5-2. Connection procedure

1. Connect the TK-260G/270G 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 blinks. When data is received by the transceiver, the green LED blinks.

Notes:

• The data stored in the personal computer must match the

model type when it is written into the flash memory.

• Change the TK-260G/270G to PC mode, then attach the

interface cable.

5-3. KPG-22 description

(PC programming interface cable: Option)

The KPG-22 is required to interface the TK-260G/270G 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-22 connects the SP/MIC connector of the TK260G/270G to the computers RS-232C serial port.

5-4. Programming software description

The KPG-56D programming disk is supplied in 3-1/2” disk format. The software on this disk allows a user to program the TK-260G/270G radios via a programming interface cable (KPG-22).

5-5. Programming with IBM PC

If data is transferred to the transceiver from an IBM PC with the KPG-56D, 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 universal connector.

To start the Firmware Programmer from KPG-56D, the Fpro path must be set up by the KPG-56D Setup.

●

This mode cannot be entered if the Firmware Programming mode is set to Disable in the Programming software (KPG56D).

●

When programming the firmware, it is recommend to copy the data from the floppy disk to your hard disk before you update the radio firmware. Directly copying from the floppy disk to the radio may not work because the access speed is too slow.

6-4. Function

1. If you press the [MON] switch while "PROGXXX" is displayed, the checksum is displayed. If you press the [MON] switch again (while the checksum is displayed), "PROGXXX" is redisplayed.

2. A transmission speed can be selected by pressing the [LAMP] switch while "PROGXXX" is displayed.

12900 bps: The LED flashes green and red alternately. 38400 bps: The LED flashes orange. 57600 bps: The LED lights orange.

Note:

Normally, write in the high-speed mode.

7. Clone Mode

Programming data can be transferred from one radio to another by connecting them via their SP/MIC connectors. The operation is as follows (the transmit radio is the master and the receive radio is the slave).

REALIGNMENT

Note: You can clone the programmed data between the

tramsceiver listed below. Frequency version must be same.
