IMPORTANT SIM CARD
INFORMATION
Spectrum Technologies recommends the purchase of a Pay As You Go
SIM Card and Service Plan with voice and text capabilities.
Some carriers send a text message or voice call after the first call of the
day on prepaid accounts. This may cause the first call or calls to fail as
your carrier sends welcome texts and screen banners. If your test call
or text fails, please wait a minute and retry.
Be sure to test your Cellular Alert to ensure calls and/or texts are suc-
cessfully received before it is used in production.
Also note that because you are using a “normal” SIM card, you can test
it with a standard cell phone.
IMPORTANT: If the SIM card is running low of funds, the Cellular Alert
might believe a call went through when it actually was intercepted by
the carrier to play a recording notifying you of low card funds.

set up
The PRO model contains a GSM cellular module that will make a voice
call or send text messages to a designated phone. It also has the op-
tion of setting a relay.
A SIM card and service plan (Pay-As-You-Go recommended) is neces-
sary but not included.
SIM Card Setup
A SIM card may be pur-
chased from a cellular
phone carrier.
First remove the an-
tenna from the top of
the case. Then remove
the module from the
Cellular Alert case by
gently pulling the module off the
Velcro that is underneath it and
sliding it up to disengage it from
the DB15 Silver Connecter as
shown in the picture to the
right.
Remove the SIM card tray from
the end of the module pressing
the small button next to it. The
tray will slide out. See picture
to right.
Place the SIM card into the tray. Slide the SIM card tray back into the
slot until it locks making sure the SIM card is facing the top of the mod-
ule.

Battery Setup
Press the battery against the foam on top (see
picture to the right) while insuring the spring
posts are properly aligned on the circuit board
below (see picture below). Caution: There are
two silver circles on the board. One post should
be on the inner circle and one post should be on
the outer circle. In no case should both posts be
on the same circle. Damage will occur.

Battery Setup—
When the batteries are first connected the display will show the firm-
ware version on the first line and indicate the cellular module cable is
connected (w/modem) on the second. This will change to the Run or
Off menu after 5 seconds.
When using an international cell phone frequency (900/1800 Hz) it is
necessary to let the unit know to reset the cellular module. Disconnect
the battery and then hold the UP button while connecting the battery.
Continue holding the UP button for two seconds, until a warbling beep
occurs indicating the button can be released. Then press and release
the SET button. The cellular module will be set to international frequen-
cies and display INTL 900/1800 for a few seconds. Be sure to verify
communications using the TEST procedure.
To change the mode back to US frequencies (850/1900) use the same
procedure except hold the DOWN button and reconnect the battery.
Once the battery is in place, it needs to be secured tightly with the Vel-
cro straps provided.

Programming
Control Panel
The DISPLAY button is used to toggle between the various modes.
These modes are Off, Test, Setup, Run. Once the desired mode is
displayed press the SET button.
NOTE: If this is the first time the Cellular Alert is being used, the first
step is to go into Setup Mode and set the Alert with a phone num-
ber. Then the Test Mode can be used to verify communications.
Off Mode—Turns the Cellular Alert off—Cancels Run Mode.
Test Mode—Used to test the alert function. When the Test Mode is
chosen, the LCD display will show diagnosis and status information.
The bars across the top of the display show signal strength. To the
right of the signal strength indicator the # of communication errors in
displayed. A strength of 10 to 31 will appear. The lower number in
both signal strength and errors the better. If the signal strength is
not the best, reposition the antenna to obtain a better signal
strength. This is done by moving the antenna out of the case and
running the antenna wire into case through the gland nut hole.
There is a 6 foot cable attached to the antenna. Once the strength
of the signal is good, press the SET button. It should display “Call
Test or Text Test”. The SET button will trigger a voice call or text
message or both (depending on the choices made in the Alert Setup
Mode) to be sent to the designated phone number. If test, is suc-
cessful LCD will read ‘Test Passed’. If not successful LCD will read
‘Test Failed’. Verify that the correct phone received call and/or text
message.
Setup Mode— Used to set the type of sensor and limits for the alert
and the type of alert desired. Using the up and down arrows, toggle
between the ‘sensor’, ‘limit’ and ‘alert’. Pressing the SET button will
select the option shown on the LCD
Sensor— In the sensor setup the choices are: Temperature
in Fahrenheit, Temperature in Celsius, Humidity, Wetness,
and Voltage. Using the up and down arrows toggle between
the choices. Once the desired sensor is displayed, press
the SET button. The display will toggle to Limit mode. Press
