Basic Operation
2.1 Opening the Hood
Caution:
the shell of the phone is attached to the base of the phone.
Be careful when opening the phone.
each phone ships with easy to remove screws on the bottom of the
phone:
Removing these two screws will allow access to the SIM card and
the power switch.
2.2 Inserting the SIM Card
The Port-O-Rotary phone uses industry standard SIM cards. The
customer must provide their own SIM card for use. Currently in North
America, T-Mobile
®
and at&t Wireless
®
use this type of small chip
to store the user’s account information. SIM cards proliferate Europe
and East Asia. Once you’ve installed your SIM card and powered up
the phone, anyone who calls your number will be calling your new
rotary phone!
The installation of the SIM card is straight forward. First remove the
cover of the phone and verify that the power switch is in the ‘Off’
position. Locate the SIM slot on the side of the cellular module. Sliding
the card in, you will hear a slight ‘click’ as the SIM is locked into place.
don’t worry, removal is as simple as pushing in the card again and
the module will release your SIM card.
Remember:
Your account minutes will be used as normal for all calls
placed or received through the Portable rotary Phone.
2.3 Power Switch
What good would a cellular phone be if you couldn’t turn it on? the Port-
o-rotary phone uses a simple slide on/off switch.
After the SIM card is installed, slide the switch to the On position. During
the boot process, the Port-o-rotary phone will give different indicators.
the phone will short-ring once indicating the phone is booting. this is
normal and does not indicate an incoming call. once the phone has
successfully connected to the cellular network, the phone will short-ring
twice. once you hear two short rings in succession, you are ready to seal
up your phone and place a call!
2.3.1 Indicator Lights
There are two small lights (LEDs) that will indicate the current status of
the cellular connection. Initially, after the unit is powered, the GM862
Status LED will blink on and off once per second. After approximately
60 seconds, the GM862 Status LED will flash quickly and then go dark
every three seconds. this indicates that the phone is registered on the
network and ready to place and receive calls. the Port-o-rotary phone
will then short-ring twice to indicate that booting is complete. You can
now carefully replace all internal parts, close the cover, and tighten the
two thumb screws on the base of the phone.
if the phone runs into problems, the led labeled PiC will blink an error
code. error codes and their meaning are listed below.

the green printed circuit board.

If you continue to run into problems, please contact SparkFun Electronics
Customer Service at support@sparkfun.com or 1-303-284-0979 x125.
2.3.2 PIN Number Entry
if during the boot process, you hear three short-rings, this indicates that
a PIN # is required for the SIM card you inserted. The Port-O-Rotary
phone will wait for you to enter a PIN #. It will allow you to enter up to
10-digits. if you have a 4-digit code, just enter 4-digits by dialing them
on the rotary. For example, if your PIN # is ‘1234’, you would dial ‘1’ then
‘2’ then ‘3’, ‘4’, and then wait.
The Port-O-Rotary phone will detect when you have quit dialing. If the
PIN # was correct, booting will continue. You should hear two short rings
indicating the boot process completed successfully.
Caution: You have ten chances to get the PIN # correct before a SIM card
shuts down completely. If this happens, the SIM card will be permanently
locked. If you have a purchased a SIM card with PIN # required, we
recommend you remove this requirement by inserting the SIM card
