1. Operation Features

Installing the (Optional) Antenna

Screw the antenna into the connector on the top of the transceiver by holding the antenna at its base and turning it clockwise until secure.

Installing the Belt Clip

Note: When first installing the belt clip, you must remove the

battery pack from the rear of the transceiver.

1 Remove the two screws from the

rear of the transceiver, then remove the small, plastic black covering that was held in place.

2 Insert the belt clip mount into the

space on the rear of the transceiver.

3 Using the 2 screws, affix the belt

clip in place.

Note: Do not dispose of the plastic

black covering! If you remove the belt clip, replace the covering into the space on the rear of the transceiver. Either this covering or the belt clip must be in place, otherwise the battery pack may not remain installed properly.

Installing the Cover over the

Speaker/ Microphone Jacks

Note: When installing the speaker/

microphone jack cover, you must remove the battery pack from the rear of the transceiver.

If you are not using a speaker/ microphone, install the cover over the speaker/ microphone jacks using the supplied screw.

Note: To lift the cover after it has been installed, use a piece

of hardened plastic or metal, such as a small screwdriver. Lift the cover by its tab, beside the screwhole, taking care not to damage the cover.

Installing the (Optional) Speaker/ Microphone

Note: When installing the optional

1 Insert the speaker/ microphone

plugs into the speaker/ microphone jacks.

2 Attach the locking bracket using the supplied screw. Note: To lift the locking bracket after it has been installed,

speaker/ microphone and its locking bracket, you must remove the battery pack from the rear of the transceiver.

use a piece of hardened plastic or metal, such as a small screwdriver. Lift the bracket by its tab, beside the screwhole, taking care not to damage the bracket.

3-1. Preface

The TK-3160 transceiver is programmed using a personal computer, a programming interface (KPG-22) and programming software (KPG-82D).

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

REALIGNMENT

3-2. Connection procedure

1. Connect the TK-3160 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 transmitting from the transceiver, the red LED lights. When data is received by the transceiver, the green LED lights.

Notes:

• The data stored in the personal computer must match the model type when it is written into the EEPROM.

• Change the TK-3160 to PC mode, then attach the interface cable.

3-3. KPG-22 description

(PC programming interface cable: Option)

The KPG-22 is required to interface the TK-3160 with 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 TK-3160 to the computer’s RS-232C serial port.

3-4. Programming software description

KPG-82D is the programming software for TK-3160 supplied on a CD-ROM. This software runs under Windows 98, ME, Windows 2000 or XP on an IBM-PC or compatible machine.

The data can be input to or read from TK-3160 and edited on the screen. The programmed or edited data can be printed out. It is also possible to tune the transceiver.
