Tether ID
The 7535 G2 can identify a device connected to the tether port by sensing an identification resistor within
the connected cable. It then configures the port appropriately for the device and enables power to the port.
See The Tether Port in Appendix B.
1.4.12 Power Management
The 7535 G2 is powered by a lithium-ion rechargeable battery pack. The 7535 G2 can be powered from
external power when used with the AC adaptor. When the 7535 G2 is powered from the AC adaptor, it
will also charge the battery pack.
An internal supercapacitor holds charge for up to ten minutes to preserve the contents of RAM while the
7535 G2’s battery is being changed.
1.5 The Portable Docking Module
The 7535 G2 can be connected to a Portable Docking Module (PDM). The model 7535 G2 terminal can
