Choosing Dial Mode
TONE PULSE
Set the DIAL MODE switch on the left
side of the unit for the type of service you
have (pulse or tone). This switch is set to
TONE at the factory. If you are not sure
which type of service you have, do this
simple test.
1. Lift the handset and listen for a dial
tone.
2. Press any number other than 0. If the
dial tone stops, you have a touch-tone
service. If the dial tone continues, you
have a pulse service.
3. If you have a pulse service, set the
DIAL MODE switch to PULSE.
Assembling & Connecting
Setting Speaker Volume
The VOLUME switch on the left side of
the machine controls the loudness of the
dialing tones you hear through the
speaker when you dial with the handset
down. You can set the volume to low (all
the way to the right), medium (center), or
high (all the way to the left).

Setting Ringer Volume
The RINGER switch on the left side of the
unit lets you adjust the ringer volume to
three different settings. Try all three to
see which volume level is best for you.
If you set the switch to "OFF", your unit
does not ring when an incoming call
comes in.
