USING HEADPHONES
To listen privately, connect low-imped­ance headphones ( available at your lo­cal RadioShack store) with a (6.35 mm) phone plug to the jack on the back of the MPS-50.
Listening Safely
To protect your hearing, follow these guidelines when you use headphones.
• Set the volume to the low est setting before you begin liste ning. A fter you begin listening, adjus t the volume to a comfortable level.
• Do not listen at extr emely high vol­ume levels. Extended high-volume listening can lead to permanent hearing loss.
• Once you set the volume, do not increase it. Over time, your ears adapt to the volum e level, so a vol­ume level that does not cause dis­comfort might still damage your hearing.

CARE
To enjoy your MPS-50 for a long time:
• Keep the MPS-50 dry. If it gets wet, wipe it dry immediately.
• Use and store the MPS-50 only in normal temperature environ men ts .
• Handle the MPS-50 gently and care­fully. Don’t drop it.
• Keep the MPS-50 away from dust and dirt.
• Wipe the MPS-50 with a damp c loth occasionally to keep it looking new.
Modifying or tampering with the MPS­50’s internal components can cause a malfunction and invalidate its warranty. If your MPS-50 is not performing as it should, take it to you r local RadioShac k store for assistance.
REPLACING THE FUSES
Importa n t N o tes:
• Let the MPS-50 cool do wn and see if it starts again before you ass ume a fuse needs to be replaced.
• Because the intern al supply fuse is located on the printed circuit board, we strongly recommend that you take it to your local RadioShack store rather than attempting to replace it yourself.
Caution:
other than those specified here. Doing so might damage your MPS-50.
Do not use a fuse with ratings
If the MPS-50 does not operate, the power fuse under the A C socket on the rear panel or the internal suppy fuses on the printed circuit board might have blown. If this happens, replace the fuses with new ones of the same type, avail­able at your local RadioShack store.
