ⅠPRECAUTIONS
ⅡPRODUCT INTRODUCTION

ⅤAFTER-SALE SERVICE

1. You’re supposed to long press the power switch to turn
the radio on or off. However, given that during the setting,
the sudden shutdown will cause the loss of the data you
have set, so we have thoughtfully made a design that in
radio system and MP3 playback setting, the radio cannot
be turned off. Also, please don't take the battery out with
the radio on.
2. As long-distance transport may cause the battery to run
out automatically, please charge the radio if it does not
respond when you first turn it on.
3. Original lithium battery is recommended.
4. Please take the lithium battery out if you plan to not use
the radio for a long time, and charge it once a month.
5. Don’t get the radio wet or use it in a moist environ-
ment. E.g. Keep it out of rain and use carefully in
bathrooms and kitchens.
6. Keep the radio away from sources of heat such as
radiators, hot water pipes or fires. And do not leave it in
full sun.
7. Keep the radio away from any solvents, such as white
spirit, paraffin or petrol.
