Before cleaning, unplug the telephone from the modular wall jack.
Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for
cleaning.
Unplug the telephone from the modular wall jack and refer servicing
to qualified service personnel when these conditions exist:
When the power supply cord or plug is damaged or frayed.
If liquid has been spilled into the telephone.
If the telephone has been exposed to rain or water.
If the telephone has been dropped or the housing has been
damaged.
If you note a distinct change in the performance of the telephone.
If the telephone does not operate normally by following the operating
