PHONE — This input is a four wire connection for a separate miuophone and earphone, as are found in
most PBX handsets It is not compatible with an ordinary phone line.
BASE 82 ~ This is an audio connection to mother Base unit, allowing up to 12 Mobile units to be
communicating with each other. The cormector is an 8 pin Mini DIN.
BC MUSIC — Audio from an external source (with external level control) is transmitted to all Mobiles and
can be monitored by the local headset in the “COM" position.
TAPE RECORDER 7 Audio from a selected mobile is routed to this connector (by the switches on top of
the Base). The recorder should have a “record level" control, since the Base does not control the amplitude
of this signal.
POWER lN — The Base requires 9 to 12 Volts DC at .S Amperes.
PHONE LEVEL- These controls adjust the incoming and outgoing audio levels for optimum results at
both ends of the telephone conversation. The person at the “far" end must be consulted for the best level.

0 The green LED above each switch, when on , indicates that the signal from the Mobile is being
received correctly.
0 When any switch is placed in a position other than “COM“, the corresponding Mobile Unit is
automatically switched to a sub-carrier mode of operation, which communicates only through the
Base. Other mobiles cannot hear this one-to-one communication, in this sub-carrier mode.
SWITCH POSITIONS:
COM — Each Base receiver’s audio is fed into the Base transmitter and is therefore retransmitted to all
mobile units. This is the “party line" mode of operation.
PHONE — The selected Mobile unit is connected to the PBX phone. [ts received signal is connected to the
two wires that normally would be the microphone connections of the PBX handset, therefore routing the
Mobile Units audio into the ‘phone system. The audio fi'om the ‘phone system is sent to the selected
Mobile unit via a subcarrier fi'equency so that only this mobile can hear it.
TAPE OUT ——Audio from the selected mobile is connected to the TAPE RECORDER RCA jack rather
than being retransmitted. The Base can communicate with the selected mobile that is using the TAPE
OUT mode when the base unit local headphone switch is in the AUX position.
AUX -The Base can communicate with the selected Mobile when the local headphone switch is in the
AUX position.

SET UP AND USE
BASE UNIT — SET UP
STEP ”1 — The detachable (BNC connectors) antennas must not be installed randomly; as they are timed
(broadly, over a 10 MHz band) to the transmit and receive frequencies of the mobile unit The markings
must be observed when installing — ie. the antenna and panel markings must be identical.
Connect the transmit and receive antennas. Note that die markings on the antennas match those on the rear
panel. The antennas must, for best results he vertical to the earth. If the Base is wall mounted, the rear
panel would be highest. Connect the antennas directly. With the Base on a table top, connect the antennas
using a right angle BNC adapter.
STEP It: — Plug in the headset, set the volume to approximately halfway, and set the headset selector to
COM.
STEP #3 — With the power switch to OFF, plug the Base power supply in. Check that all selector switches
are in the COM position and turn the power switch to ON. All green LED’s must be OFF (all Mobiles
must be OFF).
STEP M — Connect all other needed devices to the Base (86 Music, etc.).
MOBILE UNIT — SET UP
STEP if] - Connect the transmit and receive antennas. Note that the markings on the antennas match those
on the rear panel. The antennas must. for best mults be vertical to the earth. The belt and holsters
supplied with the system will support a good orientation.
STEP $2 — Set the volume to about 1/3 up, and plug the headset in. him the rearpanel MIC. LEVEL to
maximum clockwise and set the OUTPUT POWER switch to H1.
STEP #3 — Plug the battery in and push the power switch to EXT. The corresponding green LED on the
Base should illuminate. Verify operation by talking to another party at the Base, or mb the foam
mouthpiece cover on the microphones while listening at the “other end”.
Repeat for all Mobile Units.

USE & OPERATING HINTS
Although these controls/connections are simple and fairly obvious, some elaboration is useful:
ANTENNAS — The antennas supplied for the Base will suffice for most applications. In order to keep
from being in the way, the antennas for the Mobile Unit are intentionally short. Other antennas (for longer
transmit/receive distances) are available. If the Base needs to be at one end of an area (containing the
operating Mobile Units), directional antennas can he used on the Base. They will provide a significant
increase in efliciency. For best range, keep the antennas away from conductive surliaces (metal walls, the
human body, etc).
BATTERIES —The supplied batteries are lead acid (gelcell). They have no “memory “ effects, so should
be recharged alter use, even if the time of use is short (over 30 minutes). Lead acid batteries should never
be lcfi in a discharged state. They should be recharged every 3 to 4 months while in storage. The Mobile
Unit has a low battery detector that generates clicks in the earphone. When this occurs, replace the battery
within 10 to 15 minutes The battery charger supplied with the system provides an optimum charging
profile including an automatic “float charging mode" when the battery is fully charged. The battery can be
lefl on the charger indefinitely
LOW SETTINGS" Set the Output Power to LOW when all the mobile units are close to the Base unit,
and are close to each other to reduce unit to unit interference.
MIC'S l: EARPHONES — To reduce system noise the MIC should be OFF if a user does not plan to talk.
The sound level startup can be very loud. Reduce the volume before applying power. The MIC level
should he reduced for users with unusually loud voices.
The microphones are noise—cancelling electrets which need an excitation voltage (supplied by the system).
Substitute microphones may not operate properly. For best results, place the MIC approximately one
thumb’s thickness away from and to the side of the mouth. The user should speak firmly and clearly.
The earphones are 32 ohm dynamic elements in an open air configuration (the ear is not enclosed). The
user can hear mom sounds and background noise from the same ear used for the system. The car phone
should firmly contact the ear.
MJSCELLANEOUS — The entire system uses a squelch lone scheme, wherein the transmitter emits a
fixed frequency tone as well as the normal audio. The corresponding mciver has a circuit, which detects
the tone and allows normal operation. At long range the tone becomes noisy and the detector loses it, at
which point the detector shuts off (squelches) the received audio (noisy or not).
The green LED’s on the Base are driven by the tone detector in each receiver. They are ON when the
Mobile Unit is detected.
A FCC SITE LICENSE may be required to operate this unit.
TROUBLESHOOTING
The COMMdroIcc2000 7” Communication System was designed for stability over time and temperature.
It uses surface mount construction for light weight ruggedness. There are no user replaceable or adjustable
components inside the housings. The batteries will degrade in capacity over time and with recharge cycles.
One to two years real time use should be expected.
