Setup

1. Battery Installation

1. Open the battery door on the rear of the radio.
2. Install one 18650 lithium battery into the compartment, ensuring correct polarity (+/-).
3. Close the battery door securely.

2. Charging the Battery

The radio can be charged via the USB charging port (DC-IN 5V) using the provided USB cable. Connect the cable to a 5V USB power source. The battery charge indicator on the display will show charging status. The radio can be operated while charging, but charging efficiency may be reduced at high volumes.

3. Initial Power On and Volume Adjustment

2. Press any button to skip the sleep time setting if it appears.
3. Adjust the volume by rotating the [VOLUME] knob on the left side of the radio. Rotate up for more volume, down for less.

4. External Antenna Connection

For improved reception on FM, SW, and AIR bands, connect an external antenna to the 3.5mm external antenna jack. Ensure the external antenna is kept clear from power lines.

Operation

1. Band Selection

Press the respective band buttons (FM, LW/MW, SW, AIR) to select your desired frequency band.

2. Tuning Methods

The XHDATA D-808 offers several ways to tune into stations:

• Manual Search: Rotate the [TUNING] knob on the upper right side to scan frequencies. The tuning speed can be adjusted by pushing the [TUNING] knob inwards to cycle through FAST, SLOW, and STOP modes.
• Up/Down Arrow Tuning: Use the [Up] or [Down] arrow buttons to move to the next frequency. Long press these buttons to scan for the next strong station.
• Direct Frequency Input: Press the [FREQ] button, then use the number pad (0-9) to enter the desired frequency, and press [FREQ] again to confirm.
• Auto Tune Storage (ATS): Long press a band button (FM, LW/MW, SW, AIR) to activate ATS. The radio will automatically search and store strong signals into memory. Avoid areas with high electromagnetic interference for best results.

3. Memory System

The radio can store up to 500 radio frequencies (100 per band), organized into 10 pages with 10 memory locations each (e.g., P18 refers to the 8th slot on page 1).

• Manual Storage: Select the desired band. Press the [PAGE] button, then a number (0-9) to select a memory page. Long press a position number (0-9) to save the current frequency. The display will show "PAGE-SAVE".
• Recalling Stations: Press a position number (0-9) within the current page to recall a saved station. The display will show "PAGE-LOAD".

4. Advanced Features

• FM Tuning Range Setting: With the radio off, long-press the [FM] button to cycle through 64.0, 76.0, 87.0, and 87.5 MHz options.
• Medium Wave Step: With the radio off, long-press the [0] (9/10 kHz) button to switch between 9 kHz and 10 kHz tuning steps for MW.
• Long Wave Enable/Disable: With the radio off, long-press the [LW/MW] button to toggle LW ON/OFF.
• Temperature Display: With the radio off, repeatedly press [DISPLAY] until temperature is shown, then long-press [3] to toggle between °F and °C.
• Setting Time: With the radio off, long-press [TIME SET]. Enter the 4-digit time. The radio supports 24-hour format. It can also automatically set time from FM RDS broadcasts (refer to FM RDS section).
• Setting Alarm: With the radio off, long-press [ALARM]. Enter the alarm time. Press [ALARM] again to cycle through alarm modes: Radio Broadcast, Buzzer Alarm, or Alarm Off.
• Sleep Timer: Quick press the [POWER] button to activate the sleep timer. It cycles through 120, 90, 60, 45, 30, 15 minutes. Selecting "ON" turns off the sleep timer.
• Beep Function: With the radio off, long-press the [BEEP] (number 5) button to enable or disable key press beeps.
• Display Light: Press the [LIGHT] button for approximately 10 seconds of illumination. Long press [LIGHT] for indefinite illumination. Press again to turn off.
• Lock Function: Long press the [INFO] button to lock or unlock all keys, preventing accidental operation.
• Bandwidth (BW) Adjustment: Press the [AM BW] button to cycle through available bandwidths (e.g., 6, 4, 3, 2.5, 2, 1.8, 1 kHz for AM/SW; 4, 2, 2.2, 1.2, 1, 0.5 kHz for SSB). Higher BW offers better audio fidelity, while lower BW reduces interference.
• Squelch Function: Long press the [TUNING] knob for about 5 seconds to activate squelch mode. Rotate the tuning knob to set the squelch level (1-9, OFF). This mutes static until a strong signal is received.
• Display Mode: Press the [DISPLAY] button to cycle through different information on the screen: signal strength/noise ratio, time, temperature, and alarm time.
• FM RDS (Radio Data System): When an FM station broadcasts RDS data, the RDS icon appears. Press the [INFO] button to cycle through Program Service Name (PS), Date and Time (DATE), Program Type (PTY), and Radio Text (RT). RDS date information can be used to automatically set the radio clock.
• Single Side Band (SSB): After tuning to a station, press the [SSB] button. The display will show USB (Upper Side Band) or LSB (Lower Side Band). Use the [INFO] button to switch between USB/LSB. Use the [FINE TUNE] knob for precise frequency adjustment in SSB mode. Press [SSB] again to exit.
• Fine Tuning: Use the [FINE TUNE] knob for minor frequency adjustments, especially useful for SSB or to reduce interference from adjacent stations.

Maintenance

• Cleaning: Clean the radio with a dry, soft cloth. Do not use liquid cleaners, solvents, or abrasive materials.
• Battery Care: If the radio will not be used for an extended period, remove the battery to prevent leakage.

Troubleshooting

• Radio is unresponsive or frozen: Locate the small reset button access hole on the bottom of the radio. Use a small, pointed object (like a paperclip) to gently press the reset button until you feel a click. This will reset the radio to its factory defaults.
• Time changes automatically: This is likely due to the RDS auto-time setting. Disable this function in the time settings if you prefer to set the time manually.
• Battery drains quickly when off: Ensure the radio is fully powered off and not in sleep mode. If the issue persists, it may indicate a battery or internal circuit problem.
• Speaker crackling/wheezing: If the speaker crackles or wheezes, especially at full volume, it might indicate a defect.
• Poor reception on certain bands: Refer to the 'User Tips' section for band-specific reception advice. Ensure antennas are fully extended and positioned correctly.
• USB/LSB not switching or battery not charging: If specific functions like SSB mode switching or battery charging are not working as expected, it may indicate a manufacturing defect.

Specifications

Accessories Included

User Tips

• Optimizing Reception: For LW/MW bands, rotate the radio for the best signal. For SW/FM/AIR bands, fully extend the whip antenna. AIR band reception is generally best near airports. Shortwave (SW) reception is often better after sunset.
• External Antenna: While an external antenna can improve reception, some users find the built-in whip antenna performs better in certain situations. Experiment to find what works best for your location and band.
• Battery Usage: The radio can be used while charging, but for optimal charging speed, it's recommended to charge when not in use or at low volume. Battery life can vary depending on usage and volume.
• Memory Management: Utilize the memory pages effectively to organize your favorite stations by band or genre for quick access.
• SSB Listening: When listening to SSB, use the Fine Tune control for precise adjustments to clarify the audio. LSB is typically used for frequencies below 7300 kHz, and USB for those above 14000 kHz, with exceptions.
