Integrated internal battery 7.4 V, 7800 mA-hr, Lithium-ion
Internal battery operates as a UPS in the event of external power source
outage
Internal battery will charge from external power source when input
voltage is >15 V
Integrated charging circuitry
Power input on Lemo 7P0S is optimized for lead acid batteries with a cut
off threshold of 10.5 V
Power input on the 26-pin DSub connector is optimized for Trimble Li-ion
battery input (P/N 49400) with a cut-off threshold of 9 V
Power source supply (Internal / External) is hot swap capable in the event
of power source removal or cut-off
9 V to 30 V DC external power input with over-voltage protection
Receiver will auto power on when connected to external power of 15 V or
greater
