PHONECELL SX3i AMPS 6USER MANUAL 12/08/99
Step 1. Choose an Antenna Location
Your Phonecell SX3 receives operating commands from the cel-
lular network and relies upon signal strength for proper opera-
tion. Therefore, finding an antenna location with good signal
strength is critical for call quality.
A NTENNA L OCATION
T
IPS :
··Locate the antenna above ground and as close
to windows (or exterior wall ) as possible  see
Fig. 1.
··Try to install the antenna in an uninhabited area
(i.e. clo et , attic , etc.) to ensure a minimum
separation of 16 inches (40 cm) between the
antenna and the inhabitants.
··In low signal areas, the antenna should be
mounted on the buildings exterior  see Fig. 2.
··igh-gain (Yagi) antennas must be directed
toward your service providers nearest cellular
tower.
··Spike antennas must be pointed upward.
··Keep antenna cable as short as possible  long
cable runs affect call quality.
··Never splice antenna cable.
Fi . 2 Optional high-gain antenna installed on the buildings exterior. Always
direct the antenna toward the nearest cell tower of your service provider.
Fi . 1 Optional spike antenna point-
ed upward and located near the win-
dow for optimum signal strength.
Coaxial Cable

PHONECELL SX3i AMPS 7USER MANUAL 12/08/99
WARNING!

is used, connect an optional DC
input ca le to the DC Input port.
2) Turn on the FWT power using the
power switch. After approximately
10 seconds, the LED indicator on
the front of the FWT should turn
RED.
3) Connect an antenna to the TNC
antenna connector on top of the
FWT  see Figure 4.
4) Move the antenna from one location
to another until you achieve the est
signal strength possi le.
Test the cellular signal strength
by checking the LED indicator
on the front of your Phonecell:
·· Solid RED = No Service
··Solid YELLOW = Moderate
signal strength
··Solid GREEN = Good signal
strength.
5) When youre getting a strong
(GREEN) signal, youre ready
for the next step  connecting
a phone and making a call.
Antenna Location & Setup  Continued
A NTENNA T IP :
Many things can obstruct the cellular
signal, and moving the antenna as little as
one meter (3 feet) can dramatically
improve signal strength and call reception.

alternately RED and GREEN to indicate that youre now in the
programming mode. You now have two minutes to begin the
programming steps below.
Step #3 - Press: #*1 *_ _ _ _ _ _ _ _ _ _ #
The spaces represent your 10-digit telephone num er. (This is also
called a Mobile Identification Number, or MIN.) If you enter the num er
incorrectly, you'll hear three short tones followed y the programming
tone; if correct, you'll hear the programming tone again.
Step #4 - Press: #*5 *_ _ _ _ _ #
The spaces represent your 1- to 5-digit System Identifier (SID), which
ranges from 0to 32,767. This information identifies your cellular serv-
ice provider. (For example, to set up 555, enter #*5*555#.) If you enter
the SID incorrectly, you'll hear three short tones followed y the pro-
gramming tone; if correct, you'll hear the programming tone again.
NOTE: depending upon whether you enter an odd SID or an even SID,
the Phonecell will automatically set the remaining NAM parameters to
AMPS standards  as shown in the table below.
If you need to override any of the settings, continue with steps 5 - 8.

Variable Dial Time Auto SEND Delay) Option
When you place a call, your Phonecell SX3 automatically sends the phone num-
er over the cellular network after you dial the last digit  just like a landline
phone. However, to make sure you have enough time to dial the last digit, a 3-
second Auto SEN elay is programmed into the unit. This delay also affects
Special Functions such as Call Forwarding (see Special Cellular Services below).
You can set the Auto SEND Delay from 2to 20 seconds using an ordinary tone-
dial ( TMF) phone, which is sometimes referred to as a POTS (Plain Old
Telephone Service) phone. Note: you cannot change the delay while you are mak-
ing a call.
How To Adjust the Auto SEND Delay - Pick up the telephone handset and
listen for dial tone. Then, enter the User-Programming mode y pressing:
#*0 *1 2 3 4 5 6 7 8 #
The dial tone should change to a steady Programming tone and the LED
indicator on the front of your Phonecell should link alternately RED and
GREEN to indicate that youre now in the Programming mode.
Next, press: #*11 *<Auto SEND Delay> #
The < > rackets represent the Auto SEND Delay. You must enter a value
etween 2and 20 seconds. (For instance, to enter a 5-second delay, press:
#*11*5 #.)
If you enter the delay incorrectly, youll hear three short eeps followed y the
programming tone. That is your cue to re-try the steps a ove. If correct, youll
hear the programming tone again. Hang up. Your Phonecell is ready for use.
Special Cellular Services
Your Phonecell SX3 is compati le with a variety of special services such as call
forwarding, call waiting, and more. Depending upon your cellular provider, these
services may e availa le on a su scription asis. However, certain dialing

Phonecell SX3 Troubleshooting
Telephone Service is Not Working
If the telephone service is not working, first check the operation of the telephone
equipment and wiring connected to your Phonecell SX3. Test the equipment on a
different service or piece of equipment to ensure proper operation, or connect a
known good telephone device to the RJ-11 port on the Phonecell SX3 unit. This
will verify the condition of the telephone equipment and the internal wiring of the
telephone service to ensure that its working properly. If the telephone system or
wiring is not working properly, replace or repair the equipment as required.
Otherwise, contact your cellular provider or your authorized Telular distri utor.
Unable to Receive Incoming Calls
If more than one telephone or telephone device is connected to your Phonecell,
make sure that all devices are on-hook (hung up). If one extension is off-hook
(off its cradle), none of the extensions on your phone line will ring when an incom-
ing call occurs.
Moisture or Ventilation Problems
Visually inspect your Phonecell units enclosure. Moisture can damage the equip-
ment. Ventilation is also very important. If there are moisture or ventilation
pro lems, move your Phonecell SX3 to correct as necessary.
No Power
The LED lamp on the front of your Phonecell SX3 indicates the units power con-
dition. If the LED is RED, YELLOW or GREEN, your Phonecell is receiving power.
If the power cord is connected and the LED lamp is not lit, the Phonecell is not
receiving power. Verify that the AC power source and its corresponding circuit
reaker are functioning properly.
Battery Backup Failure
If youve installed atteries, the FWT must e connected to AC power for at least
24 hours to fully charge the atteries efore theyll ack up your Phonecell SX3.
Verify that the atteries have een charged for at least 24 hours and that the
power source and its corresponding circuit reaker are functioning properly. Then,
examine the atteries for wear and corrosion. Replace the atteries if necessary.
WARNING!
Only Authorized Service Personnel should remove the cover of your
Phonecell SX3. For further assistance, contact your Authorized Telular
