Page 31: Getting Started
☞ XPLR-HPG-1 does not include a battery or SIM card. As the holders for these components are inaccessible when the kit is fully assembled, you must disassemble the kit to fit them – if needed. See also Inserting the SIM and battery. - Page 32 XPLR-HPG-1 - User guide The following procedure is recommended for fitting these items collectively, but otherwise install only those that are needed for your application design. Make sure that the battery connect switch is OFF (0). Disassemble the Takachi EXPF15-6-11 enclosure as shown in Assembling the enclosure.
