Using Earphones - Sandstrom SL-DBTB18 Instruction Manual

Using Earphones

Turn down the volume before connecting the earphones (not included).
Slowly raise the volume with the earphones on until you reach your desired
volume. When earphones are connected, the speaker is automatically
muted.
Long-term exposure to loud music may cause hearing damage. It
is best to avoid extreme volume when using earphones, especially
for extended periods.
