#0.3 SUPPLIED ACCESSORIES

Microphone

DC power cable

Transceiver fuse

Mounting bracket

Microphone hanger

Screw set

Warranty card

Instruction manual

ATTENTION: MOST PROCEDURES REQUIRE THAT YOU PRESS AN

APPROPRIATE KEY IN EACH STEP WITHIN APPROXIMATELY

10 SECONDS, OR THE PREVIOUS MODE WILL BE RESTORED.

#1 PREPARATION FOR MOBILE AND FIXED STATION OPERATION

#1.1 MOBILE INSTALLATION

Install the transceiver in a safe, convenient position inside your vehicle that minimizes danger to your passengers and yourself while the vehicle is in motion. For example, consider installing the transceiver under the dash in front of the passenger seat so that knees or legs will not strike the radio during sudden braking of your vehicle. Try to pick a well-ventilated location that is shielded from direct sunlight.

#1.1.1 Installation Example

Use the supplied mounting bracket to install the transceiver inside your vehicle. To enjoy the best viewing angle, you can position the transceiver in the bracket in a number of ways as shown below.

#1.1.2 Installation Steps

Install the mounting bracket in the vehicle using the supplied flat washers and self-tapping screws. There are 4 washers and 4 screws supplied.

The bracket can be mounted with the bracket opening for the transceiver facing down for underneath mounting, or with the opening facing up.

The bracket must be installed so that the 4 screw holes on the edge of each bracket side are facing forward.

Position the transceiver, then insert and tighten the supplied hexagon SEMS screws and washers. There are 2 screws and 2 washers supplied for each side of the bracket. Double check that all hardware is tightened to prevent vehicle vibration from loosening the bracket or transceiver.

#1.2 DC POWER CABLE CONNECTION

#1.2.1 Mobile Operation

The vehicle battery must have a nominal rating of 12 V. Never connect the transceiver to a 24 V battery. Be sure to use a 12 V vehicle battery that has sufficient current capacity. If the current to the transceiver is insufficient, the display may darken during transmission, or transmit output power may drop excessively.

Route the DC power cable supplied with the transceiver directly to the vehicle's battery terminals using the shortest path from the transceiver.

If using a noise filter, it should be installed with an insulator to prevent it from touching metal on the vehicle.

It is not recommended to use the cigarette lighter socket since some cigarette lighter sockets introduce an unacceptable voltage drop.

If the power cable must be routed through a hole in the vehicle chassis or body, for example in the firewall at the front of the passenger compartment, use a rubber grommet to protect the cable from abrasion. Dismantle the fuse holder to pass the cable through the firewall.

The entire length of the cable must be dressed so it is isolated from heat, moisture, and the engine secondary (high voltage) ignition system/cables.

After the cable is in place, wind heat-resistant tape around the fuse holder to protect it from moisture. Tie down the full run of cable.

To prevent the risk of shod circuits, disconnect other wiring from the negative (-) battery terminal before connecting the transceiver.

Confirm the correct polarity of the connections, and attach the power cable to the battery terminals; red connects to the positive (+) terminal, black connects to the negative (-) terminal. Use the full length of the cable without cutting off excess even if the cable is longer than required. In particular, never remove the fuse holders from the cable.

Reconnect any wiring removed from the negative terminal.

Connect the DC power cable to the transceiver's power supply connector.

Press the connectors firmly together until the locking tab clicks. Press firmly.

#1.2.2 Fixed Station Operation

In order to use this transceiver for fixed station operation, you will need a separate 13.8 V DO power supply that must be purchased separately. The recommended current capacity of your power supply is 12A.

Connect the DC power cable to the regulated DC power supply and check that polarities are correct (Red: positive, Black: negative).

DO NOT directly connect the transceiver to an AC outlet!

Use the supplied DC power cable to connect the transceiver to a regulated power supply.

Do not substitute a cable with smaller gauge wires.

Connect the transceiver's DC power connector to the connector on the DC power cable. Press the connectors firmly together until the locking tab

Note:

For your transceiver to fully exhibit its performance capabilities, the following optional power supply is recommended: PS-33 (20.5 A, 25% duty cycle).

Before connecting the DC power supply to the transceiver, be sure to switch the transceiver and the DC power supply OFF

Do not plug the DC power supply into an AC outlet until you make aft connections.

#1.2.3 Replacing Fuses

If the fuse blows, determine the cause then correct the problem. After the problem is resolved, replace the fuse. If newly installed fuses continue to blow, disconnect the power cable and contact your dealer or the nearest Service Center for assistance.

Fuse location and ratings are:

Transceiver 15 A

DC Power Cable 20 A

CAUTION: ONLY USE FUSES OF THE SPECIFIED TYPE AND RATING.

Note: If you use the transceiver for a long period when the vehicle battery is not fully charged, or when the engine is OFF, the battery may become discharged, and will not have sufficient reserves to start the vehicle. Avoid using the transceiver under these conditions.

#1.3 ANTENNA CONNECTION

Before operating, you must first install an efficient, well-tuned antenna. The success of your installation, depend largely on the type of antenna and its correct installation. The transceiver can give excellent result., the antenna system and its installation is given careful attention.

You should choose a 50 ohm impedance antenna to match the transceiver input impedance. Use low-loss coaxial feed line that also has a characteristic impedance of 50 ohm. Coupling the antenna to the transceiver via feed lines having an impedance other than 50 ohms reduces the efficiency of the antenna system, and can cause interference to nearby broadcast television receivers, radio receivers, and other electronic equipment.

CAUTION:

TRANSMITTING WITHOUT FIRST CONNECTING AN ANTENNA OR OTHER MATCHED LOAD MAY DAMAGE THE TRANSCEIVER ALWAYS CONNECT THE ANTENNA TO THE TRANSCEIVER BEFORE TRANSMITTING.

ALL FIXED STATIONS SHOULD BE EQUIPPED WITH A LIGHTNING ARRESTER TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND TRANSCEIVER DAMAGE.

#1.4 ACCESSORY CONNECTIONS

#1.4.1 External Speaker

If you plan to use an external speaker, choose a speaker with an impedance of 8 ohm. The external speaker jack accepts a 3.5 mm (1/8") diameter mono (2-conductor) plug. Recommended speakers include the SP-50B and SP-41.

#1.4.2 Microphone

To communicate in the voice modes, plug a 600 ohm microphone equipped with an 8-pin modular connector into the modular socket on the front panel of the transceiver. Press firmly on the plug until the locking tab clicks.

#1.5 PACKET EQUIPMENT CONNECTIONS

If you intend to use this transceiver for Packet operation, you will need the following equipment.

Personal computer with communications software

Terminal Node Controller (TNC)

TNC power supply

RS-232C cable

6-pin mini DIN plug (optional PG-5A)

For the DATA connector pins, refer to "PACKET OPERATION".

Note:

Do not share a single power supply between the transceiver and the TNC.

Keep as wide a separation between the transceiver and computer as practical to reduce noise-pickup by the transceiver.

One end of the optional PG-5A cable has not been connectorized.

Attach the appropriate connector that mates with the TNC connector.

#2 YOUR FIRST QSO

If you tend to discard instruction manuals along with the packaging material please don't. The 7 steps given here will get you on the air in your first QSO right away. So, you can enjoy the exhilaration that comes with opening a brand new transceiver.

After trying the rig for a while, settle back in your most comfortable operating chair with this manual and your favorite drink for an hour or two. The time spent will be worthwhile.

Switch ON the DC Power-supply, then press the POWER switch

Turn the VOLUME and SQUELCH to approximately 9 o'clock.

Press BAND to select the VHF or UHF.

Turn the TUNING control to select a frequency.

Press and hold Microphone [PTT], then speak

Relese Microphone [PTT] to receive.

Repeat above two steps to continue communication.
