RECEIVER OPERATION 1 Getting Started Connect the battery pack and the supplied antenna. Press the POWER switch to turn the transceiver on. One of the default frequencies should appear on the display. 2 Tuning Control and Volume Control This transceiver assigns two volume and tuning control functions to the two controls.
When you press the BAND key, control of each function is transferred to the VHF band. When you press and hold the E.CHG key (or within two seconds of pressing the E.CHG key), each control temporary control of the volume or tuning control passes to the VHF band.
Whenever you are selecting frequencies, your first step should be to set the squelch control. The squelch helps eliminate “white noise” or static until you receive active communications on a frequency. There are two squelch controls, one for the UHF band and one for the VHF band.
For the European version and some other markets, Next press numeric keys 0 and 5. 5 The transceiver actually changes frequency only after the 1 kHz digit is entered. The 1 kHz digit is not displayed if it is a zero. If you do not enter the 1 kHz digit, the indicator flashes and the transceiver defaults to the previous operating frequency.
Using the Tuning Control The tuning control selects frequencies in up or down sequentially. Rotate the tuning control clockwise or counterclockwise to select the desired operating frequency. 4 Step Size Selection 1 2 14 The transceiver must be in the VFO mode to select frequency steps.
From step size 12.5 or 25 To step size 5,10, 15, or 20 Frequencies Display as 0 0 12.5 10 25 20 37.5 30 50 50 62.5 60 75 70 87.5 80 5 Programmable VFO Tuning Limits This radio provides the capability of programming the VFO tuning range, in 1 MHz band segments, as well as providing a separate programmable band scan function.
5 To confirm that the programming was properly performed rotate the Tuning control. The transceiver should not go above or below the programmed band limits. 6 Basic Receiving Functions When receiving a signal, the Main/Sub S-meter deflects and the Main/Sub BUSY indicators appea Rotate the volume control to the desired level.
TRANSMITTER WARNING: Before you attempt to transmit, attach an antenna with a low standing wave ratio to the antenna connector. Failure to provide a proper load may cause damage to the final amplifier section. Always check that the frequency is clear before transmitting.
3 TX. Stop Function The TX Stop function allows you to temporally disable the transceiver transmit, preventing accidental or unauthorized transmission. Press the F key, then press the f 2 /TX.S key to turn the TX. Stop function on or off. No indicator means the high power position has been selected.
USING THE MEMORY 1 Microprocessor Memory Backup All memory channel data is backed up in EEPROM. It is not lost unless you reset the memory. All other data that you set is retained by a secondary lithium battery that will provide memory backup for about 20 days if you remove the battery pack or external DC power.
4 Memory Contents Each memory channel can store information as shown in the chart below. X =Can be stored in memory Normal Split Channel Channel RX frequency TX frequency Tone(CTCSS) frequency, Tone (CTCSS) status Frequency step Shift status, REV on/off X N/ A DTSS code.
6 Entering Split Channel Frequencies Use the numeric keypad to select the desired receiver frequency, tone and other information. If the desired frequency is already on the display, continue to step 2. Press the M key. The memory indicator will flash.
3 Select the desired call channel transmit frequency. 4 Press the M key. 5 Press and hold the PTT switch and press the CALL key. 6 Release the PTT switch. 8 Recalling Memory Channels Press the MR key. You can change the memory channel by the following two methods.
10 Memory Channel Character Display You can display the memory channel frequency with your own spelling. It may be up to six characters long. You can use numerics 0 to 9 and the letters A 4 Enter your message with the keypad. See the list on page 45 for the key combinations for each letter.
SCANNING You must adjust the squelch to the threshold point for proper scan operation. You cannot use scan in conjunction with the tone alert function and paging. Scanning occurs separately in the VHF and UHF bands. You can reverse the direction by turning the Tuning control or MESSAGE key.
3 Scan Options The following scan options are available: * Memory Scan Scans through those memory channels that have data stored and that have not been locked out. This function operates only in the memory mode. * Band Scan Scan proceeds over the entire band.
2 Press the F key, then the 0/L.OUT key. A * indicator appears below the memory channel number on the display, indicating that channel will be skipped in the memory channel scan mode. 3 Repeat steps 1 and 2 to lockout any other channels you may want to skip.
5 Press and hold the M key for longer than one second, then press the 4 key. Notes 1 Initialize the VFO memory (VFO RESET) to clear both programmed limits simultaneously. Press and hold the F key and turn on the power. You can reprogram either limit independently.
2 Press the F key, then press the MR key. 3 The VFO frequency and the last used memory channel are scanned alternately. 9 CALL/VFO Scan 1 Press and hold the CALL key for longer than one second in VFO mode. 2 The frequency and CALL frequency are scanned alternately.
REPEATER OPERATION 1 Transmitter Offsets All amateur radio repeaters use a separate receive and transmit frequency. The receive frequency may be above or below the transmit frequency. Most repeater configurations fall into one of the following categories.
4 Manual Offset Selection 5 The Reverse Function The factory default sets the automatic offset frequency. You can select any offset frequency in the range 0 to 99.9 MHz in 100 kHz steps. Some repeaters use a ’ reverse pair’, that is, the transmit/receive frequencies are the reverse of other repeaters.
6 Tone Operation Some repeaters require a control signal to activate them. Several different methods are currently in use. In the United States, sub-audible tones are sometimes used. This transceiver will generate sub- audible frequencies. In Europe and the United Kingdom, a 1750 Hz tone is used in transmitting.
7 Autopatch Operations (U.S.A. versions only) Some repeaters offer a service called autopatch. This feature allows you to dial a telephone number from your transceiver and carry on a telephone conversation. This function requires the use of a DTMF (Dual Tone Multi Frequency) keypad.
8 DTMF Memory You can store 10 DTMF telephone numbers up to a maximum of 15 digits long in memory. Storing DTMF Codes 1 Press the M key, then press the MHz key to select the DTMF code entry mode. 2 Enter the DTMF code on the keypad 3 Press the MR key after entering the DTMF code.
Making a DTMF Call 1 Hold the PTT switch down and press the MHz key. 2 Press the numeric key (O-9) for the channel where the DTMF code is stored. 3 The DTMF code appears on the display. Note Transmission continues until the whole code string is recalled, even if the PTT switch is released.
CTCSS OPERATION The CTCSS unit (TSU-7) is included only with models delivered to the United States and Canada. The CTCSS unit (TSU-7) installation instruction are shown on page 63. If the Continuous Tone Code Squelch System (CTCSS) function is activated, the transceiver will not open squelch until it receives the proper PL tone (tone squelch).
THE DUAL TONE SQUELCH SYSTEM (DTSS) DTSS allows squelch activation in the receive mode when the transceiver receives a three-digit code matching the DTSS code you have selected.
Paging uses a DTMF (Dual Tone Multi Frequency) signal and is useful in calling members of a group, a specific station, or for waiting for a call from another station.
2 Paging Code Memory There are 8 paging code memories. Memory Cod e 1~ 6 Use Stores your station ID code in memory. Automatically stores the calling station’s code during reception. Can temporarily set the code for the station to be called. Stores group codes and local station codes in memory.
