Setting the volume level Rotate the VOL button clockwise to increase the volume, counterclockwise to decrease it. Set the volume to the desired level.	Minimum volume	Maximum volume
	Volume button
Setting the level The noise suppressor eliminates “white noise” (background noise in the absence of a useful signal). If the squelch level is too high, then weak signals will not be received, but the quality of strong signals received will be very good due to the low noise level. With a low squelch level, weak signals from correspondents will be heard, but at a high noise level. 1. Press the SQL key. The SQL icon will appear on the display and the SQL level will be shown in the position for the memory channel number. There are 21 levels available, between 0 and 20. “0” is the lowest setting. 2. Rotate the channel selector, or use the UP/DOWN keys on the microphone, to set the desired level. To return to normal mode, press PTT, or any of the keys on the front panel; If you do not press anything, the transceiver will still store this setting for 5 seconds, then return to its original status. The new squelch level will be saved until another setting is entered.	Squelch level
VFO mode The VFO setting is preset at the factory. The VFO (Variable Frequency Oscillator) allows you to change the frequency according to the selected channel step by rotating the channel selector or using the UP/DOWN keys on the microphone. VFO mode is also used when programming data to be stored in memory channels or to change transceiver settings. 1. Check current mode on the display. If the “M” or “C” icon is not displayed on it, then the radio is already in VFO mode. 2. If the “M” or “C” icon is displayed on it, press the “V/M” key until the icons disappear.	VFO mode

Conventional repeaters operate in DUPLEX mode. This means that the repeater receives a signal on one frequency (UP - LINK) and transmits on another (DOWN - LINK). The difference between these two frequencies is called the offset frequency. If the frequency UP - LINK is higher than the frequency DOWN - LINK direction is positive, if lower, the shift direction is negative. The offset can be set between 0 and 99.995MHz on this radio.	(-600kHz)
Press the F key. While the F icon remains on the display, press the MHz key. The display shows the current status of the shift direction and shift frequency. The default value is 0.60 MHZ (600KHz) in the negative direction. Press the MHz key until the desired offset direction is set. If you need SIMPLEX mode (reception and transmission frequencies are the same), then you need to select a position when the - and + icons are not visible on the display.	shear direction
1. Rotate the channel selector or UP/DOWN keys on the microphone to change the shift frequency. 2. It changes according to the set channel pitch. 3. In this mode, if the F key is pressed again, the offset frequency can be changed in 1MHz steps for quick setting. 4. Press PTT or any key other than F or MHZ on the front panel to return to the original status.

Installation /

Many repeaters require a CTCSS tone or DCS code as a “key” to log into the system, called “selective calling”. Sometimes CTCSS or DCS is used on the repeater output to open the squelch of a particular radio. In this mode, the radio subscriber will hear the caller through the other subscriber's repeater ONLY when the corresponding tone/code is received. The combination of CTCSS noise reduction and DCS codes function is not available; For a given memory channel, only one or the other can be used.

1. Press the TS/DCS key. These settings will be indicated by the T/SQ/DCS icons on the display and the CTCSS tone frequency or DCS code number. Press the same key to select T/SQ/DCS as shown in the picture.

2. Numbers like 88.5 represent the CTCSS frequency in Hz. When it is displayed with only a T icon, the radio transmits a CTCSS tone while the PTT button is pressed (encoding) and the repeater gives access to the radio channel of the radio station that sends the 88.5 Hz tone.

3. Press the same key again so that the SQ icon appears on the display. Then the CTCSS decoder mode will turn on at this frequency. This will enable the TSQ tone squelch mode. 4. Press the same key again until the display shows a 3-digit number and the DCS icon. This is a DCS code, the DCS code encoder/decoder is enabled.

To select CTCSS or DCS frequencies, rotate the channel selector or press the UP/DOWN keys to change the tone or code. Press any key other than the TSDCS/UP/DOWN key to enter the setting and return to the original state. The T/SQ/DCS icon on the display indicates the current status. To turn off the CTCSS/DCS coding mode, you simply press the TSDCS key and the T/TQ/DCS icon will disappear.

The CTCSS encoder/decoder frequencies can be set to different values. When you set the encoder frequency, the decoder frequency will automatically be set to the same, but it can be changed. A standard set of 39 different CTCSS tones are available, as shown in the diagram below. The DCS codes for the encoder/decoder cannot be different, they are selected from a list of 104 codes as shown below.

CTCSS frequency (Hz)

DCS Codes

PLEASE NOTE: Depending on the level of deviation, the incoming DCS encoded signal may not open your station's DCS squelch. If this occurs, return to the DCS mode setting and press the CALL key. The display will show a decimal point in the 10MHz digit; after that install required code. This setting can also be stored in a memory channel.

1. Press the CALL key. The C icon will appear on the display and the transceiver will enter CALL mode. In this mode, the channel switch or UP/DOWN keys cannot change memory channel numbers or frequency.
2. Press the CALL key again or press the V/M key to exit CALL mode. 3. In CALL mode, no viewing functions are available. 4. To store the desired data in the operational channel, use memory programming commands. Write the selected parameters to channel C. The parameters of the operational channel can be changed, but channel C itself cannot be deleted or hidden.

Receiving signals

Make sure the antenna is connected to the radio, the transceiver is turned on, and the volume and squelch levels are set to the appropriate levels.

Select the receiving frequency you need, or frequencies to browse the channels you need to listen to. The S-meter shows the signal level between the BUSY and FULL marks when the transceiver detects an incoming signal.

If the S-meter indicates a signal but there is no sound from the speaker, check the volume level, squelch level, and CTCSS/DCS decoding settings, which are explained elsewhere in this manual.

The Monitor function is designed to receive weaker signals. Press and hold the SQL button for more than 1 second. Regardless of the signal level, the squelch will open, the BUSY icon will appear on the display, and you will hear a signal through the speaker. Press any key on the front panel to enter noise canceling mode.

Broadcast

1. Select the desired frequency. You must be sure that you are authorized to operate on this frequency. Check that there is no signal so as not to interfere with correspondents broadcasting on that frequency at that time. 2. Select transmit power. Press the FUNC key, then press the CALL key while the F icon is shown on the display. By pressing the CALL key you can select one of three power levels. The Lo icon means low power, Mi means medium power. When the transceiver is set to High Power mode, these icons will not appear on the display. The transmit power level cannot be changed while the PTT key is pressed.
3. The default is high power. Press the PTT key on the microphone to transmit and release to receive messages. During transmission, the power level is shown on the radio display in the form of segments. LOW POWER = 2 segments, AVERAGE POWER = 3 segments, HIGH POWER = 5 segments.	low power average power high power
4. When powering the transceiver from a car battery, avoid long transmission times with the engine off, as this will lead to intense battery drain. Check battery voltage frequently. Also, current consumption increases significantly when the headlights, stereo, air conditioning and other auxiliary systems of the car are turned on. If all these systems are turned on, the output power of the transmitter is reduced, so some of them are turned off to reduce the load on the car's battery. Monitor the traffic situation when working on the road. Check local regulations regarding the use of radio frequencies and mobile radio transmitters in the area.

Parameter setting mode

Important: Please read the following pages in full before changing any settings.

THE PARAMETERS CANNOT BE CHANGED WITHOUT ACTIVATING THE INSTALLATION MODE.

In installation mode, some of the radio parameters can be changed to suit your requirements. Options are selected from the options menu.

Please note: Alphanumeric channel labels will not appear in the menu unless they have been programmed in advance!

Using Installation Mode 1. Press and hold the FUNC key for more than 2 seconds to enter parameter setting mode. Use the SQL key or UP/DOWN value keys to select the default menu

default values

2. Rotate the channel selector to select the desired setting. 3. Press SQL or the UP/DOWN keys again to enter the selected setting into the radio's memory. The transceiver is now ready for additional parameter adjustments. 4. Press any key other than SQL/UP/DOWN to exit the parameter setting mode. The only exception is the mode for setting alphanumeric channel labels for exit, from which you can only press the PTT, FUNC, MHz and TSDCS keys. Details and features of the parameter setting mode menu The specific procedure for setting some parameters is explained in more detail later.

Setting the channel step The channel step is selected in VFO mode. Refer to the chart below to determine your actual cadence.
Type The scanning type allows you to select one of the conditions - scanning by timer (TIMER) or by time of presence of the signal carrier (BUSY). Timer scanning allows the radio to resume scanning 5 seconds after finding a busy channel, regardless of whether it remains busy after the 5 seconds have elapsed. When scanning the BUSY type, the radio resumes scanning only when transmission has ended on a given channel and the signal is not indicated. Scanning modes are explained later.
Sound signal The beep is turned on when BEEP-ON is set. This means that a beep will sound when you press some keys. When set to BEEP-OFF, the beep sound is disabled.

TOT transmission time limit

TOT is especially popular in repeater systems. This mode prevents the user from transmitting after a certain period of time has elapsed. By setting this function as required by repeater systems, the radio alerts the user with an audible signal 5 seconds before the end of this time. When the time expires, the transceiver automatically stops transmitting and enters receive mode. This allows the repeater to switch to TOT mode for the next correspondent. Until the PTT button is released and pressed again, the transceiver will not transmit.

Pause timer between TOT Penalty transmission sessions

When the TOT mode is set, this function prohibits transmission if less than the time set in this mode has passed from the moment of one PTT press to the next.

.....

Auto shutdown mode APO - OFF

In this mode, the transceiver automatically turns off. This is useful for the mobile station to avoid draining the car battery. If there is no radio traffic, a beep will sound after 30 minutes and the transceiver will automatically turn off.

Ring tone frequency

This mode allows you to activate the operation of some repeaters or correspondents that are in standby mode by emitting an audible tone of a certain frequency. Typically, a repeater system does not require a tone if the repeater is activated.

Blocking transmission on a busy BLCO channel

This function disables transmission if there is a signal on the transmit frequency. The default value is BCLO-OF. By activating this function, the radio transmits only when:

Alphanumeric label

Channels stored in memory mode may be shown on the display with an alphanumeric mark instead of a frequency. First program the channels into memory. A total of 67 characters are available, including letters A-Z, and numbers 0-9.
