4.Use Digital Interface’s 4-position switch to adjust audio level by making a test call.

•Lift digital telephone handset from its cradle, then press Conference Phone’s “On/Off” key.

Important: the digital telephone handset must be “off-hook” for the duration of the call; the Digital Interface disables the handset microphone when the Conference Phone is on.

•Place the call from the digital telephone’s keypad.

Note: The Conference Phone keypad cannot be used to dial calls through most digital phone systems; the keypad on the digital tele- phone must be used.

•Adjust the audio level with the 4-position switch (level 1 is highest, level 4 is lowest). If the setting is too high for the digital telephone, the party at the other end of the line may get noise feedback (buzz, tone, or squeal); if the setting is too low, your voice may be too faint to be heard.

•End the call by pressing the Conference Phone’s “On/Off” key and hanging up the digital telephone handset.
