Using the Lithium-ion battery as a Universal Power Supply
(UPS)
The receiver has an internal Lithium-ion battery. The internal battery will only charge
from an external power source that delivers more than 15 volts, for example, an AC
power adaptor. The receiver is supplied with a mains power supply unit that recharges
the battery inside the receiver when it is connected through the adaptor to the modem
port or the Lemo port. When you use the receiver on large projects, from a permanent
or semi-permanent base station location in a site trailer, Trimble recommends that
you use this power supply at all times to keep the internal battery charged. This
provides an uninterrupted power supply and will keep the site operational for more
than 10 hours after a power failure.
Keep all batteries on continuous charge when not in use. You can keep batteries on
charge indefinitely without damage to the receiver or to the batteries.
Removing the rechargeable Lithium-ion battery
The internal Lithium-ion battery should be removed only at an authorized Trimble
Service Center. If the battery is removed at an unauthorized service center, the
remaining warranty on the product will be void.
