Frequently Asked Questions - RF-CR-300 Renkforce

How to charge the battery of the RF-CR-300 radio?

The radio can be charged in three ways: via the USB-C port (cable included, max. 5V/2A), via the solar panel by orienting it to the sun, or via the hand crank (130-150 rpm). It is recommended to turn off the radio before charging. The red indicator lights up during charging and turns off when the battery is full.

How to connect a Bluetooth speaker to the radio?

Turn on the radio by pressing and holding the power button. It automatically enters Bluetooth mode (BT icon displayed). Activate Bluetooth on your device, search for the identifier 'DF-580' and connect. A beep confirms the connection. The radio sound will then be played through the connected device.

How to save and select radio stations?

Press the MODE button to choose FM or AM. For automatic search, press and hold the search button for 3 seconds. Found stations are saved automatically. Use the + and - buttons to switch between saved stations.

How to use the SOS function?

Press and hold the SOS button (located under the radio) for 1 second to trigger the audible alarm. To stop it, press and hold the same button for 1 second. Caution: This action also resets the radio to factory settings (stations and Bluetooth connections erased).

How to clean the radio?

Use a dry, lint-free cloth. Do not use harsh cleaning agents, alcohol or solvents. Do not immerse the device in water. To maintain the IPX5 rating, ensure the protective cover is closed after use.

What does the IPX5 protection rating mean?

IPX5 means the product is protected against low-pressure water jets, but only when the rubber cover is closed. If the cover is open (for charging or inserting an SD card), the device is no longer water-resistant.

How to reset the radio to factory settings?

Use a pointed object (like a paperclip) to press the reset button (20) on the radio. The radio turns off and returns to factory settings. You can then turn it on normally.

Can I use the radio as a backup battery for my phone?

Yes. Connect your phone's charging cable to the USB-A port (18) on the radio. The built-in battery will power the connected device. Make sure the radio is sufficiently charged.

How to turn on the flashlight and reading lamp?

Press the dedicated flashlight button to turn it on or off. For the reading lamp, unfold the solar panel; it lights up automatically. Fold the panel to turn it off.

What microSD card can I use and what formats are supported?
