• For additional information, see Band Scan on page 11.
• Memory Channel C is used to store the CALL channel frequency.
• Memory Channel D is used to store the transmit frequency used for odd offset operation.

Memory Channel Contents

• Each Memory Channel is capable of storing: Frequency
• SHIFT status (Offset)
• TONE status, (Encode, Decode, and Frequency)
• Receive Frequency for odd offset operation. See page 14.

4. Press any key or the microphone PTT switch to return to the receiver frequency display. The subaudible tone will be transmitted whenever the PTT switch is depressed.

TONE SQUELCH (CTCSS)
This function allows you to remain squelched until the proper Tone frequency is received. If you are on a busy frequency, this can be quite an aid.

1. Press the TONE key. The “ENC” will appear on the display panel. Press the TONE key again. The “DEC” will, be “ENC”. appear next to the Your radio will now remain sequel- Ched until the proper code is re-ceived.
2. You should ensure all stations, you wish to communicate with, use the same Tone Frequency.
3. To release the Tone Squelch function (Normal noise activates squelch), press the TONE key again. The “ENC” and “DEC” will disappear from the display.

REPEATER Operation
All amateur radio repeaters utilize a separate receiver and transmitter section. The receiver frequency may be either above or below the transmitter frequency. This transceiver allows you to store the frequency, offset frequency (0.6, 1,6, 5.0 and 7.6 MHz.) and offset directly- h in Memory Channel (1-9 and A). To select the desired transmitter offset direction, press the SHIFT key. Each time you press the key, the radio will advance from one offset to the other, i.e. “-” to “+” to “Dual”. To select the desired transmitter offset, press the SHIFT key, and then rotate the Main Dial or depress UP/DOWN button on the microphone. Each time you rotate or depress these controls, the radio will advance through the following steps: “0” to “0.6” to “1.6” is “5” to “7.6”. After the offset has been stored, press any key, except the SHIFT key, or depress the PTT switch.

The normal display will return. REVERSE Function The REV key has been provided to allow you to reverse the transmit and receive frequencies. To use the Re- verse function, press the REV key. The REV indicator will light in the display to remind you that you are working a reverse repeater pair. To return to normal operation, press the REV key again.

TRANSMISSION

Caution

1. Ensure that an antenna with a low standing wave ratio (SWR) is attached to the antenna connector before attempting to transmit. Failure to provide proper termination may result in damage to the final amplifier section.
2. Always check to ensure the frequency is clear before transmitting.
   • Simplex Operation
   • Select the desired operating frequency using any of the methods described above.
3. Press the microphone PTT switch. The ON AIR indicator will light.
4. Speak into the microphone. The recommended distance to the mi– microphone is 2 inches (5 cm).
5. Talking Being too far away may result in reports of weak audio.
6. Release the microphone PTT switch to return to the receive mode. The ON AIR indicator should go out.

Odd Offset Operation
For other than 600 kHz, 1.6 MHz, 5.0 MHz and 7.6 MHz splits.

1. Select Memory “d” in memory mode.
2. Select VFO and dial up the transmit frequency required.
3. Press the F key then press the MW key to store the transmit frequency into memory “d”.
4. While still in VFO mode dial up a receive frequency.
5. Press the SHIFT key to select offset, and continue to press until the transceiver cycles through +, – and Cimnlay to “Muo!”
6. Key the PTT switch and you will transmit on memory “d”. Release it and you will receive on frequency displayed in VFO.

INSTALLATION

Location
The transceiver may be installed in any position in your car, where the controls and microphone are easily accessible and safe operation of the vehicle or the performance of the set will not be interfered with. Refer to the diagrams for the installation of the Mounting Bracket:

Power Requirements

The transceiver can be operated from any regulated 12 or 13.8 V negative ground source. For mobile use, power connections should be made directly to the battery to minimise the possible ignition noise pickup. For fixed base operation, a 13.8 V D.C. Power Supply capable of providing at least 15 A continuously is required.  Connect the red lead of the power cable to the Positive (+) terminal, and the black leads to the Negative (-) terminal of the D.C. Power Supply.

BASE STATION INSTALLATION

For fixed base operation, a 13.8 V D.C. Power Supply capable of providing at least 15 A continuously is required. Connect the red lead of the power cable to the Positive (+) terminal, and the black lead to the Negative (-) terminal of the D.C. Power Supply.
