The SD/MMC

and SIM card slots reside under the batteries near the
base of the dome.
The SD/MMC card slot is located to the left of the MINTER inside
the battery pocket (Figure 1-9) and connects an optional SD/MMC
card to the receiver board to provide memory. Once installed, the SD/
MMC card usually remains inside the receiver. The data that resides
on the SD/MMC card can be accessed via the USB or serial port, or
Bluetooth wireless technology. A secure digital card can be purchased
at a local computer supply store.
The SIM card slot is located to the right of the MINTER inside the
battery pocket and allows a standard SIM card to be installed in the
receiver. Once installed, the SIM card provides a unique identification
for the receiver’s GSM module and enables the receiver’s GSM
functionality based on the subscribed services (the receiver board
accesses the GSM module which accesses the SIM card). The SIM
card usually remains inside the receiver. The GSM module with the
SIM card installed can be accessed via Modem-TPS for configuration
purposes. A SIM card can be purchased from a local cellular provider.
