This symbol is intended to alert
you to the presence of uninsu­lated dangerous voltage within
the product’s enclosure that might
be of sufficient magnitude to con­stitute a risk of electric shock. Do
not open the product’s case.

Important:

• Cordless phones such as this one
require AC power to operate. When
AC power is off, you cann ot dial out
or receive incoming call s using your
ET-927. For this reas on, th e ET- 92 7
should not be your only telephone.
To be safe, you should also ha ve a
phone that does not require AC
power to operate (not a cordless
phone), so you can still make and
receive calls if there is an AC power
failure.

• Some cordless phones operate at
frequencies that might cause inter­ference to nearby TVs and VCRs.
To minimize or prevent such interfer­ence, the base of the cordless
phone should not be placed nea r or
on top of a TV or VCR.
