  • 3 bright white LEDs.
  • FM / AM / NOAA band.
  • Recharge cell phone for emergency calls.
  • Charging, discharging protection.
  • 3-way power enabled: hand crank to wind up internal alternator / expose to sunlight / DC recharger with supplied USB to micro USB cable.
  • IPX3 waterproof.


The HT-746 can be powered from the following sources:

  • DC power from a USB power source, such as a computer or standard USB AC/DC converter.
  • Solar power.
  • Hand crank power.


  • Insert the micro USB end of the supplied charging cord into the Micro USB JACK of the device, and the other end into the computer USB port or other USB AC/DC converter. The red battery indicator illuminates when the battery is charging.

 Before first use of HT-746, it is recommended to fully charge the rechargeable battery through the USB Micro socket. The USB power source could be your computer or standard USB AC/DC converter. The red battery indicator will illuminate when charging. Continue to charge the HT-746 for several hours, or until the charging light turns off. The HT-746 is now ready for use.


  • Place the product with the solar panel facing the sun. It takes about 10-12 hours of daylight to fully recharge the battery. The red battery indicator illuminates when battery is charging.




  • Lift the HANDCRANK.
  • Turn hand crank either clockwise or counterclockwise (crank speed=130rpm) for 3-5 minutes to recharge the internal battery. It is important to use this feature when the unit has been idle for more than 60 days. The red battery indicator illuminates when the battery is charging.
  • For subsequent charges, turn the hand crank for one minute (crank speed=130rpm) to produce: 15~20 minutes of continuous light for three LEDs; 15-20 minutes of continuous radio usage (medium volume); 3-5 minutes of talk time (depending on phone model).



  • Turn the POWER/VOLUME dial clockwise to turn the radio on and control volume.
  • Select AM or FM, WB with radio band selector. For better reception, extend the RADIO ANTENNA.
  • Turn TUNER DIAL to select a station. The green tune light will turn on when a station is engaged.
  • Weather Band Tuning—Weather channels frequencies are as follows: 162.400 MHz, 162.425 MHz, 162.450 MHz, 162.475 MHz, 162.500 MHz, 162.525 MHz and 162.550 MHz.

  • Press the flashlight switch to turn it ON.
  • Press the flashlight switch to turn it OFF.


  • Recharge the HT-746 by the methods mentioned above prior to connecting the device to be recharged.
  • Turn the POWER/VOLUME control to OFF position.
  • Lift the rubber tab on the side of the unit.
  • Insert the USB end of your specific phone charging cord into the USB port of the device and the other end to the device to be charged.
  • Your device will show the charging sign.
  • If your device does not show any charging sign, it is probably because the HT-746 is not charged enough. In that case, the HT-746 has to be recharged further by the methods mentioned above.
  • If you have used your device until the battery has depleted again and you are interested in further recharging your device (i.e., to make another phone call, etc.), repeat the stages in section 5, from the beginning each time.


  1. Due to different cell phone models, current consumption and battery status, times of power supply may vary.

6. Troubleshooting Guide



Phone does not recharge when connected to HT-746.

A lower voltage in the HT-746—recharge the HT-746 prior to connecting the device.

HT-746 does not recharge newer cell phone models.

Due to constant increase in current consumption of newer cell phone models, the HT-746 might only recharge such cell phones when their battery is completely depleted.

Poor radio reception.

-  Stretch the antenna to its maximum length.

-  Move the radio from side to side and upside down.

-  Go to a higher point, or outside if you are in a building.

-  Radio reception is dramatically reduced when charging from USB.

  • Stay away from other electronic devices.


  • Do not clean unit with harsh abrasives or any solvents.
  • Unit is NOT totally waterproof—only waterproof according to IPX3. DO NOT submerge in water.
  • The contents of batteries are hazardous waste. Always recycle or dispose of batteries


  • Batteries may explode if mistreated. Replace the battery only with the exact type.

     It is recommended to use the assistance of a technician or electrician.

  • Device shall not be exposed to excessive heat, fire, or the like. (Temperature range:

    32 °F to 131 °F.)

  • Only use this product as intended.
