OPERATING INSTRUCTIONS
1. Plug each unit into an AC outlet.
2. Set each intercom unit to the desired channel using one of the
four CHANNEL buttons.
3. Turn the POWER/VOLUME knob clockwise until the intercom’s
POWER indicator lights. Set the VOLUME knob to mid-level.
4. To call a unit, momentarily press the CALL button, this will
produce a call tone on other intercoms set to the same channel.
5. When the receiving unit sounds, press the TALK button to talk,
release to listen. Adjust the VOLUME knob as required. For best
results, speak in a normal voice, arms length from the intercom.
6. For hands-free operation or for continuous audio monitoring of a
room, simply press the AUTO TALK button on the intercom. When
the AUTO TALK button is locked down, the intercom will monitor
the sound in the area. When the sound level is loud enough
to trigger the voice-activation, the intercom will automatically
transmit the sound on the selected channel.
