Advanced Features
Power Modes The receiver can be powered from one of three different
sources:
• Its internal battery (typically for field operations)
• The power line, through the AC adapter and the docking
station (typically for office work). These two items are part
of the basic supply.
• An external DC source using the POGO cable or the
cigarette lighter adapter connected to the bottom of the
receiver through its 16-pin connector. The POGO cable
and cigarette lighter adapter are optional accessories.
The receiver can be switched to Suspend mode. This is a
power saving mode typically used in the field to allow a quick
restart after a pause. In this mode, only some parts of the
receiver are powered for the sole purpose of restoring the
context of use in which the receiver was when it was switched
to Suspend mode. GNSS reception is not however maintained
in this mode. That is why the receiver should NOT be used in
that mode while collecting raw data or/and operating in RTK
mode.
The receiver can also enter the Suspend mode automatically
in case of a very low battery after dismissing successively the
two “low battery” alerts, or after an idle time that you can set
through
Start, Settings, Power (Advanced tab) (See also Power
Management on page 6). When collecting raw data and/or
operating in RTK mode, please clear this option so that the
receiver can never enter this mode.
Please note the following points whenever the receiver is
connected to a docking station powered by the AC adapter:
• The receiver won’t start if you try to power it up from the
docking station without having an internal battery
previously inserted in the receiver.
• If the receiver is currently on, the power input is switched
automatically from the internal battery to the AC adapter.
• Whether the receiver is on or off, the internal battery is
tested for its charging status. If it is discharged, a
charging sequence is started automatically. The end of
charging is also automatically detected, meaning you are
allowed to keep the battery and/or the receiver on the
docking station without any risk of overcharging.
• The AC adapter and docking station are designed to
provide power to the receiver while ensuring the charging
