Radio Shack TAD 3809 - Manual (Page 23)

23 Troubleshooting
CARE
Keep the TAD dry; if it gets wet, wipe it dry immediately. Use
and store the TAD only in normal temperature environments.
Handle the TAD carefully; do not drop it. Keep the TAD away
from dust and dirt, and wipe it with a damp cloth occasionally to
keep it looking new.
Modifying or tampering with the TAD’s internal components can
cause a malfunction and might invalidate its warranty and void
your FCC authorization to operate it. If your TAD is not perform-
ing as it should, take it to your local RadioShack store for assis-
tance. If the trouble is affecting the telephone lines, the phone
company can ask you to disconnect your TAD until you have re-
solved the problem.
