4. Setup

4.1 Battery Installation

1. Locate the battery compartment on the back of the radio.
2. Open the battery compartment cover.
3. Insert 3 x AA batteries (not included) according to the polarity markings (+/-) inside the compartment. The radio also contains a built-in 3.6V Ni-MH rechargeable battery pack.
4. Close the battery compartment cover securely.

4.2 Initial Charging

Before first use, it is recommended to fully charge the internal Ni-MH battery pack. Connect the supplied USB charging cable to the DC IN 5V port on the back of the radio and plug the other end into a standard 5V USB power adapter (not included) or a computer USB port. The red charging indicator light will illuminate.

5. Operating Instructions

5.1 Powering On/Off

Slide the Power Switch to the ON position to turn on the radio. Slide it to OFF to turn off the radio.

5.2 Band Selection

Use the Band Selection Switch to choose your desired frequency band: FM, MW (Medium Wave), or SW (Short Wave).

If SW is selected, further refine your choice using the Short Wave Band Selection (SW1~7) switch.

5.3 Tuning

1. Extend the Pull Rod Antenna for FM and Shortwave reception. For MW, the internal ferrite bar antenna is used.
2. Slowly rotate the Tuning Knob to scan for stations.
3. Observe the Frequency Dial to identify the frequency of the station.
4. Adjust the antenna position for optimal signal clarity.

5.4 Volume Adjustment

Rotate the Volume Knob to increase or decrease the audio output level.

5.5 Using Earphones

Plug 3.5mm earphones into the Earphone Socket for private listening. The internal speaker will be muted automatically.

6. Power Supply Options

The GR-98 offers multiple ways to power the device and its emergency functions:

• USB 5V Charging: Connect a USB cable to the DC IN 5V port for daily power supplement and to charge the internal Ni-MH battery pack.
• AA Dry Batteries: Insert 3 x AA batteries into the battery compartment for convenient power replacement, especially outdoors.
• Manual Hand Crank Dynamo: Fold out the Emergency Generator Handle and rotate it evenly and gently to generate power. This is ideal for power-free self-rescue and charging the internal battery.

7. Emergency Functions

7.1 LED Emergency Lighting

Slide the Emergency Lighting/Alarm Switch to the light icon position to activate the built-in LED flashlight for illumination during power outages or outdoor activities.

7.2 Red Flashing Warning Light & Siren Alarm

Slide the Emergency Lighting/Alarm Switch to the alarm icon position to activate the red flashing warning light and a loud siren alarm. This can be used to send distress signals in emergency situations.

7.3 Mobile Phone Emergency Charging

Connect your mobile phone or other small electronic device to the Hand-operated Power Generation DC 5V Output (USB OUT 5V) port using a suitable USB cable. Use the hand crank to generate power and charge your device. This function is intended for emergency power supplement only, not for daily long-term charging.

8. Maintenance

• Cleaning: Wipe the radio with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Battery Maintenance: If the radio will not be used for an extended period, remove the AA dry batteries to prevent leakage and potential damage to internal circuits and the casing.
• Storage: Store the radio in a cool, dry place away from direct sunlight and extreme temperatures.

9. Troubleshooting

• No Power: Check if the batteries are correctly installed and charged. Ensure the power switch is ON. Try hand-cranking to see if it powers on.
• Poor Reception/Static: Extend the antenna fully for FM/SW. Rotate the radio for MW to find the best signal. Move away from strong electromagnetic interference sources (e.g., computers, TVs, large appliances). Shortwave signals can be affected by weather and time of day.
• No Sound: Check the volume level. Ensure earphones are not plugged in if you intend to use the speaker.
• Hand Crank Not Charging Device: Ensure the device is properly connected to the USB OUT port. Crank steadily and at a reasonable speed.

11. Safety Warnings & Precautions

• Charging Safety: Use a standard 5V low-voltage USB power supply for charging. Do not use high-power fast chargers to avoid battery overheating, bulging, and internal circuit damage.
• Waterproof & Moisture: This product is non-waterproof. Keep away from rain, liquid splashes, and humid environments to prevent short circuits and equipment failure.
• Hand Crank Usage: Rotate the hand crank evenly and gently. Do not crank violently or at ultra-high speed to avoid internal transmission structure wear and damage.
• Emergency Charging: The mobile phone charging function is only for emergency power supplement in power outage and disaster scenarios, not for daily long-term charging.
• Light & Alarm Usage: Do not keep the LED light and siren alarm working continuously for a long time to avoid excessive power consumption and shortened battery life.
• Signal Reception: Shortwave signals are affected by weather, time zone, and electromagnetic interference. Slight signal fluctuation and noise are normal phenomena, not quality defects.
• Anti-Drop & Impact: Avoid violent dropping, squeezing, and strong impact to prevent pointer deviation, dial damage, and internal component looseness.
• Electromagnetic Interference: Keep the radio away from high-power electrical appliances to reduce signal noise and ensure stable reception.
• Disassembly Prohibition: Do not disassemble or modify the internal structure privately. Man-made damage is not covered by warranty.

12. User Tips

• For best shortwave reception, try tuning at different times of the day and night, as propagation conditions vary.
• When using the hand crank, a steady, moderate pace is more effective than fast, erratic cranking.
• Always extend the telescopic antenna fully for FM and SW bands to maximize signal strength.
