Model 295F and 295W Clean Phone™ Telephone
Microphone Sensitivity and Speaker Volume Adjustment
The speaker volume and microphone sensitivity controls are factory-set to a nominal value. This value
may not be suitable for the particular noise environment where Model 295 phone is to be installed. To
obtain the best performance possible in your particular area, we recommend that the following adjustment
procedure be performed after Model 295 is installed in its final location and in typical ambient noise
conditions. You will need a small standard screwdriver for the adjustments.
1. Remove the unit from its wall mounting, but do not unplug it.
2. Call someone, or have someone call you from a handset type telephone. They should be outside your
location and should read a few paragraphs of text.
3. See Figure 5. While they are
reading, locate the MIC adjustment
on the rear of the unit, and turn it
counterclockwise until it is all the
way down.
4. Locate the SPEAKER adjustment.
Turn it until the speaker volume is
set to a level that the person talking
can be comfortably understood
when you are a few feet from the
telephone.
5. Turn the MIC adjustment clockwise
until the speaker starts to "cut out"
the speech from the person
talking—when it sounds like the
first syllable of every word is
missing.
6. Back the MIC adjustment off until
the speech comes back to normal
but no farther. This adjustment
should require only an eighth to a
quarter turn in the counter-
clockwise direction.
7. Try a test conversation on the line. If the quality of communication is unsatisfactory, begin with Step
1 of this section, and readjust Model 295.
Model 295 is now fully adjusted for the acoustics and noise conditions within your area.
