1. It is recommended to set the side power switch PWR ON/OFF to the OFF position because this turns off the display to save money
2. Replace batteries
3. Turn the side switch to the ON position.

Stand

The rear panel of the receiver has a stand for placing the receiver on a table.

Switching ranges

1. When the radio is on, press one of the buttons to select the appropriate band:
   • SW - short waves (HF),
   • MW - medium waves (SW),
   • FM - ultrashort waves (VHF).
2. The VHF range is divided into two:
   • FM1 - 67-87 MHz,
   • FM2 - 87-108 MHz,
     you can switch between them by short pressing the FM button.
3. MV - medium wave range:
   • 522-1710 kHz (MW), uses 9 kHz tuning steps.
4. HF range - short wave range.
   The short wave reception range is 3.2 - 21.85 kHz and is divided for convenience into 7 ranges:
   • SW1 - 4.75 MHz (60 meters)
   • SW2 - 5.95 MHz (49 meters)
   • SW3 - 9.5 MHz (31 meters)
   • SW4 - 11.65 MHz (25 meters)
   • SW5 - 15.10 MHz (19 meters)
   • SW6 - 17.15 MHz (16 meters)
   • SW7 - 21.45 MHz (13 meters)
     which are switched by pressing the SW key.

Frequency tuning

The receiver has three configuration methods:

1. manual
2. semi-automatic
3. automatic scanning with recording of radio stations into memory cells

Manual setting

Press TUNING ^ or TUNING v to change the receiving frequency up or down by the minimum tuning step (9 kHz on MW, 5 kHz on HF and 50 kHz on VHF - approx. translation).

Semi-automatic tuning

Press and hold TUNING ^ or TUNING v to start a semi-automatic search for radio stations up or down in frequency. The reception numbers will change quickly on the display. When a radio station is found, the search will stop and audio from that channel will begin to play.

Fully automatic setup and saving

Press the MEMORY button for 2 seconds and the receiver will begin a fully automatic search for radio stations. Channels on which a signal is detected will be stored in memory.

The three tuning methods can be used in combination to find radio stations faster.

Manually saving frequency to memory

Tune to a radio station using one of the methods described above. To save a setting to memory:
*short press the MEMORY button. The memory cell number will light up on the display.

• to change the number of the memory location for saving, press TUNING ^ or TUNING v. For each range there are 29 memories 1-29.
• To save to a memory location, briefly press MEMORY again.
  The frequency will be saved in the specified cell, and the old value of the frequency stored in it will be replaced with a new one.

Total number of memory cells: 29 MW, 29 SW and 29 FM, a total of 87 channels.

Recalling a frequency from memory

After storing frequencies fully automatically or manually into memory as described above, you can recall frequencies to tune to.

• short press the M+ button to enter channel mode.
• you can navigate through the channels stored in memory by repeatedly pressing the M+ button
• You can also press M+ once to switch to channel mode and then use the TUNING ^ or TUNING v buttons to quickly move up or down channels. In memory channel mode, the display will show "M". After three seconds of inactivity, the "M" symbol and channel address will disappear from the display.

Saving and recalling your favorite radio stations

Saving favorite channels into memory is intended for those users who often listen to their favorite radio station.
To use this mode:

• tune to the desired frequency using the TUNING ^ or TUNING v buttons
• press and hold the FAVORITE button. If FAVORITE flashes once on the display, then this frequency has been successfully saved to the FAVORITE list.

While in any mode, you can call up your FAVORITE station by briefly pressing the FAVORITE button. The radio will switch to playing your FAVORITE radio station.

Volume adjustment

Press the VOLUME ^ or VOLUME v buttons to change the volume level.

How to block the receiver

In the mode when the clock is displayed or when the radio is on, press the LOCK button for 2 seconds. The "key" symbol will light up on the display. In this mode, all buttons are locked, except for the power ON/OFF and mute MUTE buttons. The receiver is unlocked in clock mode or when the radio is on by pressing the LOCK button for 2 seconds. The "key" icon will disappear from the screen and the operation of the radio buttons will return to normal mode.

Connecting an external 5V DC power supply

Power in external power mode is supplied through the DC IN 5V jack.

Connection: connect an external 5V power supply with a micro USB connector to the receiver. Now the external power is working and the radio is ready to be used from it.

Disconnection: Disconnect the power plug from the micro USB socket.

Recommendation: Use a charger with DC 5V/1A output. Otherwise, the radio will not function normally, and if the voltage exceeds 5V, it will be damaged.

Note: If the receiver already has batteries installed, before connecting to an external power source:

• if the display shows a clock, turn off the receiver (with the switch on the side - approx. translation).
  *then connect external power to the receiver
• turn on the receiver power (switch on the side - approx. translation).

Setting the time (hours)

When you first installed the batteries, the display shows the clock with the wrong time.

To set the time, use the ON/PFF button to switch the receiver to the clock display mode:

• Press and hold the TIME (SW) button. The hours and minutes will flash on the display
• press and hold the HOUR (MW) button to set the clock, then set to the desired hour by briefly pressing the HOUR (SW) button
• press and hold the MINUTE (FM) button to set the clock, then set to the desired hour by briefly pressing the MINUTE (FM) button
• To exit the clock mode, briefly press the TIME (SW) button.

To quickly move the clock forward or back 1 hour, press the TIME (SW) keys, then use the TUNING ^ or TUNING v arrows to move the clock up or down an hour. Then briefly press the TIME (SW) button. The receiver uses a 24-hour time format.

Setting an alarm

The radio has an alarm function. First set the exact time as described above. Then, you can set an alarm clock, which at a given time will turn on the receiver, playing a radio station in the CB, HF or VHF bands.

Setting the alarm time

To set the alarm time (hours and minutes):
1) use the side switch and the ON/OFF button to switch the receiver to the clock display mode
2) Short press the TIME (SW) button
3) when the alarm symbol appears on the display, long press the TIME (SW) button
4) when the alarm symbol flashes, set the hours and minutes using the HOUR (MW), MINUTE (FM) buttons.
5) Short press TIME (SW) to exit the alarm setting mode.

Turning on the alarm

To turn on the alarm:
1) put the receiver into clock display mode.
2) Briefly press the TIME (SW) button. If the alarm symbol is lit on the display, the alarm will sound.
3) turn on the radio by long pressing the ON/OFF key, select the desired band and tune in to a radio station that broadcasts around the clock, adjust the desired volume using the VOLUME ^ and VOLUME v buttons.
4) turn off the radio using the ON/OFF key.

Disabling the alarm

1) use the side switch and the ON/OFF button to switch the receiver to the clock display mode.
2) Briefly press the TIME (SW) button. If the alarm symbol is not lit on the display, the alarm will not sound.

Sleep Timer

The CS-106 radio does not have a sleep timer function (unlike Retekess V111, where it is configured by short presses on the ON/OFF key when turned off).

Using the Antenna

In the short wave (SW) and ultra-short wave (FM) bands, use a 360-degree rotating whip antenna, extending it to its full length. If strong reception causes distortion or interference of radio stations, fold one of the whip antenna sections.

Listening to medium waves (MW):
The receiver has a built-in magnetic medium wave (MW) antenna that is directional when receiving radio signals, so you can rotate the radio body to improve radio reception.

Display backlight

For use especially at night, the receiver display is equipped with a backlight. Pressing any button lights up the display for 5 seconds, then if no buttons are pressed, the backlight turns off automatically to save energy.

9/10 kHz step switching in medium wave (MW) mode

To switch between 9 and 10 kHz steps, press the MW key for 3 seconds when switched off. A number will light up on the display - the currently set step in the medium wave range. Change the pitch as necessary using the TUNING ^ and TUNING v buttons. After waiting 2 seconds, the selected step will be saved.

The step of radio stations in the medium wave range of 10 kHz is used in the USA, Canada, Mexico and other countries of North and South America, and 9 kHz in other parts of the world. The default step is 9 kHz and there is no need to switch it - translator's note.

Attention!

1. If the radio is not used for a long time, please remove the batteries from the receiver.
2. If the sound is quiet, distorted or the backlight is dim, please replace the batteries.
3. Please do not apply strong pressure, protect the receiver from collisions, impacts, falls and water.
4. Do not place the receiver in direct sunlight or in areas with high temperature or humidity. Do not use or store the device at temperatures below -5 degrees Celsius or above 50 degrees Celsius.
5. Do not use chemicals to clean the receiver to avoid damaging the receiver and display coatings.
6. Do not disassemble the receiver housing or attempt to change the parameters of the built-in components yourself.
