ATTACHE PHONE MODEL LAP-2000
GENERAL INFORMATION ABOUT YOUR ATTACHE PHONE
Your Livermore Data Systems Model LAP-2000 Attache Phone is a portable
and complete radio telephone to be used with the public mobile telephone
service offered by the various telephone companies in the United States.
Telephone calls to or from your Attache Phone are made over a radio link
to a nearby transmitting and receiving base station operated by the local
telephone company. Continuation of the call over regular telephone lines
is then possible to any telephone in the world.
The Attache Phone is capable of operating through either the operator
accessed Manual Telephone System (MTS) or the two-way dial service (IMTS)
with controls and displays not available on any other portable telephone.
Construction is all solid-state, and is modularized for easy service or
maintenance. All eleven channels of the VHF Mobile Telephone Service
are provided in every Livermore Attache Phone, enabling you to use your
phone anytime, anywhere in the United States.
The transmitter operates at a nominal frequency of 158 MHz and delivers
18 watts of output power to either the internal antenna (concealed behind
the pocket in the Attache case lid) or to the external antenna. Your
Attache Phone has been designed to operate just like the telephone in
your office. You can talk and/or listen to the party at the other end
of the line simultaneously. However, in order to conserve battery power
when using your Attache Phone in areas offering manual service (MTS) it
is recommended that you use the Push-to-Talk feature.
Your personal telephone number, 5 digits for MTS subscription service or
7 digits for IMTS service, is programmed into your Attache Phone by your
dealer or his service center. Your dealer will fully describe the oper-
ation of your Attache Phone and will advise you of special procedures
that may be required in your service area.

USING YOUR ATTACHE PHONE
Your Attache Phone comes equipped with the latest features and accessories
to make this one of the most useful personal or business investments you
will ever make. The controls and displays have been designed to be con-
venient, and after minimum training and actual use,relatively simple to
use. To gain the maximum benefit from your Attache Phone communications
system you should carefully read this manual before initially using it,
and periodically review its contents to assure proper maintenance and
service.
CONTROLS AND INDICATORS
The following paragraphs briefly describe the basic controls and indica-
tors illustrated on page 12of this manual. All switches (other than the
spring loaded HOOKSWITCH and PTT switch) are alternate action, push-on,
push-off type switches.
A. POWER -When the POWER switch is depressed your Attache Phone
is being powered , from its own internal Nicad Battery. When-
ever either the Cigarette lighter adaptor or the AC wall plug
accessory are used, the POWER switch should be in the OFF (up)
position. This will allow your Nicad Battery to be recharged
while power is being derived from an external source.
B. SPEAKER - The SPEAKER switch allows the received audio signals
to be directed to the AUDIO MONITOR SPEAKER. This permits you
to monitor the channels to listen for a vacant one without
actually holding the handset to your ear or to let others lis-
ten in on your conversation when desired. If the VOLUME con-
trol is set too high and the handset is near the SPEAKER, feed-
back as in a public address system will create a disturbing
audio squeal.
C. IMTS - The IMTS switch selects the mode in which the unit must
operate. For IMTS service the switch is depressed and the IMTS
indicator will be lighted. For Manual (MTS) service the switch
should be OFF (up) and the IMTS indicator off.
D. PTT (CONTROL PANEL) - The PUSH-TO-TALK is a momentary action
switch used primarily on the IMTS network when placing a mobile
-2-

to mobile call over a single IMTS channel. (See the section
describing Mobile to Mobile calls.) The PTT indicator (function)
can be turned off by alternately pressing the button or by
"hanging up" the handset on the HOOKSWITCH.
E. JK, JL, JR, ••• YS- These eleven switches and indicators repre-
sent the eleven VHF two-way channels that are available for use
throughout the North American Continent.
Not all channels are available in any one metropolitan area.
For most effective use, consult the National Mobile Telephone
Service Directory and push down the channel buttons for those
stations in your service area. This will allow your equipment
to give maximum attention to these channels and prevent inter-
• ference from channels outside your service area. Your Attache
Phone will scan or search only those channels whose switch
buttons are down.
F. BATT LOW - The BATTery LOW indicator is a warning that your
internal Nicad Battery has discharged to a level established
as a safe, rechargable level. Recharge the battery when this
indicator is lighted. Prolonged use after this lamp is lighted
could cause damage to your battery and prevent it from ever being
recharged.
G. XMIT - The XMIT (Transmit) indicator is lighted whenever your
Attache Phone is radiating 18 watts of power. Since your Nicad
Battery is capable of supplying only enough energy when fully
charged to transmit for approximately fourty-five (45) minutes
this light serves as a reminder to limit the length of your calls
and as a positive indication that your transmitter is ON.
H. BUSY -When the handset is OFF-HOOK, a BUSY lamp on the MTS mode
shows the channel is busy. In this case, to make a call choose
another suitable channel. In the IMTS mode, a BUSY lamp ON when
the handset is OFF-HOOK indicates that you have failed to seize
the channel for one or more of the following reasons: channel
BUSY, equipment was not locked to an idle tone, range to station
is too great. In any of these cases, you must go back ON-HOOK
before trying again to make a call. When the handset is ON-HOOK,
this lamp goes on only when the equipment is decoding an incoming
call.

THE EXTERNAL PLUG-IN ANTENNA
In order to counteract the shielding effect of the metal body of an
automobile in which the Attache Phone is used, a plug-in quarter-wave
antenna and cable assembly is supplied. This antenna can be clipped
to the gutter of the car roof and the cable run in through the window.
Transmitter power, which is normally connected to the Attache Phone
antenna in the case cover, is automatically switched to the external
antenna when the plug is inserted.
A longer, 5/8 wavelength automobile antenna which will give greater
range or a stronger signal may alternately be used if its cable end
has the proper plug (Type Switchcraft 440 or equivalent). For this
alternative, check your dealer or service agency.
THE BATTERY CHARGER
This accessory plugs into the usual wall socket and transforms the
AC 115 volts to a lower D.C. Voltage for charging the battery. The
charging current is limited by a series ballast lamp (type GE-82) to
protect the battery. Do not energi~e the transmitter while this battery
charger is in use.
The time required for a full charge at the rate recommended by the
battery manufacturer is 14 hours. It is perfectly safe to leave the
charger on for a longer period.
THE CIGARETTE-LIGHTER POWER ACCESSORY
The Attache Phone may be powered from the automobile 12 volt power system
and its battery recharged by the use of this accessory. Noise and voltage
transients on the auto power line are removed by regulatory circuits to
protect the Attache Phone and a second ballast lamp (type GE-64) limits
the battery charge current. Use of this accessory whenever the Attache
Phone is in the automobile is recommended both for charging the battery
and making or receiving a call.

HOW TO MAKE A CALL
1. Handset is ON-HOOK.
2. In your car, for best results plug in the external antenna and
use the cigarette-lighter plug-in for the car battery power.
However, it is always possible to use the internal battery and
the internal antenna, although the steel car body will decrease
your range.
3. Depress the channel buttons for the channels available in your
local area. (To raise a button, push it again; these are push-
push switches).
4. Select IMTS or MTS mode in accordance with the following table,
and turn the power ON.

5. Check to see that your equipment is locked . to an idle channel.
The Channel Light will be steady.
6. Pick up handset OFF-HOOK. This automatically turns on your trans-
mitter and attempts to seize the channel. If there is a problem,
the XMIT light will go off and the busy light will go on. In this
case, you must go back ON-HOOK to re-establish a lock to an idle
channel.
7. If no problems, you will receive a dial tone and be able to dial
your number, or the operator may respond if you are roaming out
of your home area and you may place your call through her.
8. Replace handset ON-HOOK after each call to release channel.
MTS MODE
5. Pick up the handset. The equipment scan stops. Check if the
channel is available or busy . If busy, you may hear a voice and
the busy light will go on. Step to another channel using the
Channel Sequence Switch until an open channel is available . NOTE:
In IMTS areas, the busy lights may go on when the MARK IDLE channel
tone is present on an IMTS channel. The MTS Roamer may use this
channel in his usual way.
6. Press the handset PTTfor 2 to 3 seconds. Listen for the operator
to respond and place your call through her. Give your telephone
number and city of registration for identification and billing.
For example; "Mobile Operator, this is YS12345, San Jose registry.
I'm calling 555-1212."
7 . At the end of the conversation, sign off and release the channel:
For example: "This is YS12345 Clear."
