Installing a SIM Card
The W315A/325A embedded computers have a built-in GSM/GPRS cellular module to provide long-range
communication. SIM (Subscriber Identity Module) cards are used to authenticate and identify subscribers when
connecting to a network.
Follow these steps to install a SIM card:
Step1:
Before you install a SIM card, make sure the embedded computer is powered off.
Step2:
Use a screwdriver to remove the protective cover to access the slot.
Note that the SD slot and SIM card slot for the W315A/325A share the same
protective cover.
Step3:
When
inserting the SIM
card, make sure
the chip is facing
upwards. Plug the
SIM card directly
into the slot.
Step 4:
Power on the embedded computer and start the operating system.
Step 5:
To operate GPRS connection, refer to the operating system user’s manual for details.
NOTE
To remove the SIM card from the slot, press the SIM card in slightly with your finger, and then remove your
finger to allow the card to spring out partially. You may now grasp the top of the card with two fingers and pull
it out.
Installing an SD Card for Storage Expansion
The W315A/325A embedded computers have an SD slot for storage expansion. The SD slot allows users to plug
in a Secure Digital (SD) memory card compliant with the SD 1.0 standard for up to 1 GB of additional memory
space, or a Secure Digital High Capacity (SDHC) memory card compliant with the SD 2.0 standard for up to 16
GB of additional memory space. The following steps show you how to install an SD card.
The SD slot is located on the right side of the W315/W325 casing. To install an SD card, first remove the
protective cover to access the slot, and then plug the SD card directly into the slot.
Step 1:
Use a screwdriver to remove the screws holding the SD/SIM card slot’s outer cover.
Step 2:
After
removing the cover,
insert the SD memory
card into the slot.
