The SPSx50 GPS receiver uses an internal
rechargeable Lithium-ion battery.
The battery can be replaced only at an
Authorized Trimble Service Center.
The receiver can also be powered by an external
power source that is connected to the Lemo or
modem port.
The operational time provided by the internal
battery depends on the type of measurement
and operating conditions. Typically the internal
battery provides >15 hours operation as a base
station and >20 hours as a rover during
measurement operations using the internal
radio.
<<I’ve entered the information from page 1 of
the datasheet in the first part of the sentence,
above - however, the operating hours on p 3
are not specified in the datasheet yet, so not
sure whether this is correct. Rob says that
Nick will provide information.>
<<Product team. Please check number of hours
listed here against number of hours listed in the
Tech. Specs. chapter. Different numbers. Needs
clarification>>
<<Note to Product team: All warnings need to be
repeated in Safety Information chapter. Sorry for
the duplication but it is part of our legal
requirements.>>
