2. Adjust the volume and tone to fit your needs by adjusting the VOLUME (See figure
#25)
and TONE (See figure #26) controls until you find the right levels for you. The
Volume Control increases sound volume. Slide the Volume Control to the right
to increase the volume and slide it to the left to decrease the volume. The Tone
Control allows you to fit your specific hearing needs. Slide the Tone Control to the
left to boost the lower frequency range. Slide the Tone Control to right to boost the
high frequency range. This allows individuals with BOTH high frequency and low
frequency hearing loss to use the CSC50 Phone.
3. For additional, situational amplification, press and hold the HANDSET BOOST but-
ton located just below the earpiece on the inside of the handset
(See figure #27). By
pressing and holding this additional handset boost button, you get an extra 10 dB
gain of amplification.
IMPORTANT NOTE: The Handset Boost button is designed to be used when listening
only. When you are ready to speak, release the button. Press it again when the extra
amplification is necessary. Failure to release the button when speaking will result in the
other party not hearing you. Use this additional handset boost button (See figure #27) for
the following reasons:
a. The caller has a very soft speech
b. There is a lot of background noise
c. You are in a noisy environment
d. The connection on the phone line is weak
CAUTION: This telephone can produce very high (loud) sound levels. Repeated incre-
mental exposure to amplification levels greater than 18 dB may be harmful to people
without hearing loss. Always adjust the volume control to the minimum setting after using
the phone and alert other users that hearing damage can potentially result from misuse.
