In order to hear a dial tone, you must select the telephone termi-

switch (H) is set to headset position, and volume (G) is set
to mid-range.
2. Remove the telephone's handset from the telephone and lis-
ten for a dial tone in your headset.
3. If there is no dial tone or it is not clear, stepwise slide the
termination switch (I) through all 9 settings (along the "A-I"
range), listening for the clearest possible dial tone. If the dial
tone is just as clear in position "A" as in position "I", leave the
switch in position "A".
4. When you hear the clearest dial tone, you have located the
correct termination setting.
