Page Your First Qso If you encounter problems or there is something you would like to know more, read the detailed explanations given later in this manual. Page Front Panel Note: This section describes only the main functions of the front panel controls. Explanations for functions not described here are provided in the appropriate sections of this instruction manual.

K market models only. Displays the frequencies, Menu settings, Memory name and other information. When making test transmissions, connect a dummy load in place of the antenna. Note: E market models use an N-type antenna connector while other models use an M-type SO connector. Page 23 Example 1 To enter Many functions on this transceiver are selected or configured via a software-controlled Menu rather than through the physical controls of the transceiver.

Once you become familiar with the Menu system, you will appreciate its versatility. You can customize the various timings, settings, and programming functions on this transceiver to meet your needs without using many controls and switches.

Page Offset Programming Flow Repeaters, which are often installed and maintained by radio clubs, are usually located on mountain tops or other elevated locations. This combination of elevation and high ERP allows communications over much greater distances than communicating without using repeaters. The transceiver is programmed for an offset direction as shown below. To obtain an up-to-date band plan for repeater offset direction, contact your national Amateur Radio association. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station.

Page Chapter 7 Memory Channels In Memory Channels, you can store frequencies and related data that you frequently use so that you do not need to reprogram that data every time. You can quickly recall a programmed channel through simple operation. A total of Memory Channels when using the Memory Name function are available for storing frequencies, modes, and other operating conditions.

When you recall a named Memory Channel, its name appears on the display in place of the stored frequency. Names can be call signs, repeater names, cities, names of people, etc.

In order to use the Memory Name function, the Memory Channel capacity must be set to channels. This function is useful, for example, when the frequency you want to monitor is near the frequency stored in a Memory Channel. Page 40 The tables below illustrate how data is transferred between Memory Channels. The AL Channel is available for K market models only. The Call Channel can be recalled instantly no matter what frequency the transceiver is operating on.

Page Chapter 8 Scan Scan is a useful function for hands-off monitoring of your favorite frequencies. By becoming comfortable with all types of scan, you will increase your operating efficiency. This transceiver provides the following types of scans. The transceiver scans the entire band of the frequency you selected. For example, if you are operating and receiving at It then continues or stops scanning according to which Resume Mode you have selected. Page Chapter 9 Selective Call These Selective Calls allow you to ignore not hear unwanted calls from other persons who are using the same frequency.

You can store a DTMF number 16 digits max. Many repeaters in the U. The default setting is milliseconds. The external speaker jack accepts a 3. We recommend using the SPB speaker. Press firmly on the plug until the locking tab clicks.

Attach the supplied microphone hanger in an appropriate location using the screws included in the screw set. Keypad serial data. No Connection. DC 8 V, mA max. Programming Cable via the microphone jack. Note: Ask your dealer about purchasing a Programming Cable. Be careful with the polarity of the capacitor.

Are you ready to give your transceiver a quick try? Reading this section should get your voice on the. The instructions below are intended only as a quick guide. If you encounter problems or there is something you would like to know more, read the detailed explanations given later in this manual.

The various indicators and the current operating frequency appear on the LCD. Note: This section describes only the main functions of the front panel controls. Explanations for functions not described here are provided in the appropriate sections of this instruction manual. Press and hold for. In this mode, you can change memory channels using. K market models only. When making test transmissions, connect a dummy load in place of the antenna.

Connect a If desired, connect an optional external speaker for clearer audio. This jack accepts a 3. See page 6. Press to lower the operating frequency, Memory Channel number, Menu Number, etc.

Hold down to repeat the action. Also press to switch between values for functions with multiple choices. Press to raise the operating frequency, Memory Channel number, Menu Number, etc. Also press to switch between. Identical to the front panel CALL key. Identical to the front panel VFO key. Identical to the front panel MR key. The default function of this key is 1 MHz step. The microphone keypad keypad models only allows you to make various entries depending on which mode the transceiver is in.

Turn the Volume control clockwise to increase the audio output level and counterclockwise to decrease the output level. The purpose of Squelch is to mute the speaker when no signals are present. With the squelch level correctly set, you will hear sound only while actually receiving signals. The higher the selected squelch level, the stronger the signals must be to receive. The RF Power meter shows the relative transmit output power.

Note: If you continuously transmit for longer than the time specified in Menu No. M4 market version only: The output power of M4 market models cannot be adjusted. It is fixed at 25 W. Do not transmit at high output power for an extended period of time. The transceiver could overheat and malfunction. Note: When the transceiver overheats because of ambient high temperature or continuous transmission, the protective circuit may function to lower transmit output power.

This is the basic mode for changing the operating frequency. If the desired operating frequency is far away from the current frequency, it is quicker to use the MHz Tuning Mode. When the desired frequency is far away from the current frequency, you can directly enter a frequency using the Mic keypad keypad models only. For example, to select Note: If the entered frequency does not match the current frequency step size, the frequency is automatically rounded down to the next available frequency.

Many functions on this transceiver are selected or configured via a software-controlled Menu rather than through the physical controls of the transceiver. Once you become familiar with the Menu system, you will appreciate its versatility. You can customize the various timings, settings, and programming functions on this transceiver to meet your needs without using many. Welcome to ManualMachine.
