CONSOLE DESCRIPTION
The 5-channel Wireless Intercom Consoles provide a wireless audio
communication link between up to five Console stations and one
or two remote Wireless Doorbell Intercom units.
The intercom uses digital signals to control the stations called and
provide a unique “house code” that prevents other nearby intercoms
from accessing the system. Either of two radio frequencies can
be selected for the intercoms to further eliminate the chance of
interference from adjacent systems.
The Console features five station number pushbuttons for selecting
the party to call. The ALL CALL button can be used to call all
stations. Pressing the TALK button calls the selected station, then
controls the direction of the conversation. Each intercom user
presses their TALK button to activate the microphone during the
conversation.
The Doorbell works as Console station 4 or 5. Pressing the
Doorbell’s TALK button sounds a “ding-dong” (station 5), or “dong”
(station 4) at the Console, then the conversation begins by pressing
the units’ talk buttons.
For privacy, a MUTE switch on each Console can be set to prevent
Wireless Doorbell tones and ALL CALL messages from sounding
through that Console’s speaker.
The Console can be placed on a table or shelf, or mounted to a
wall with the screws provided. The antenna adjusts for table or
wall mounting. Power for the Console is provided by a plug-in
transformer.
The Doorbell attaches to a wall with the mounting plate provided.
Two 9-volt alkaline batteries power the Doorbell intercom.

IMPORTANT FCC NOTICE
Radio controls provide a reliable communications link and fill an important need
in portable wireless signaling. However, there are some limitations which must be
observed.
• For U.S. installations only: The radios are required to comply with FCC Rules
and Regulations as Part 15 and FRS Part 95 devices. As such, they have limited
transmitter power and therefore limited range.
• A receiver cannot respond to more than one transmitted signal at a time
and may be blocked by radio signals that occur on or near their operating
frequencies, regardless of code settings.
• Changes or modifications to the device may void FCC compliance.
• Infrequently used radio links should be tested regularly to protect against
undetected interference or fault.
• A general knowledge of radio and its vagaries should be gained prior to acting
as a wholesale distributor or dealer, and these facts should be communicated
to the ultimate users.
• This device complies with FCC Part 15 and FRS Part 95 Rules and Regulations.
Operation is subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
• This device and its antenna must not be co-located or operating in conjunction
with any other antenna or transmitter
