3. Wait for the base unit's indicator to turn off. Then lift the
extension telephone's handset and confirm that you hear a
dial tone and that there is no interference or background
noise. If there is a problem, repeat these steps.
If you cannot get a dial tone, unplug the cords from both phone
jacks and reset the units (see "Resetting the System" on
Page 12).
ADDING MORE EXTENSION UNITS
You can add as many extension units (Cat No. 43-161) to the
system as you want. Simply install the extension by following
Steps 4 and 5 in "Installation." Then follow the steps in "Setting
the Security Code" on Page 10 to set each extension's code.
You can use only one extension at a time, even if you install more
than one. If you lift the receiver on a phone connected to an ex-
tension unit while another extension unit is being used, you hear
a busy signal.
USING THE SYSTEM WITH A COMPUTER
MODEM
Simply plug your computer modem's telephone cord into an ex-
tension unit's modular jack. The system supports speeds up to
14,400 bps.
Note: If there is static on the system, you might need to set your
modem to a slower speed for effective communications.
