Managing Power
Turning the Receiver ON/OFF
To turn on the receiver, press and hold the power button until the LEDs briefly flash. When the receiver
is turned ON, the receiver’s channels initialize and begin tracking all visible satellites at any time and
location.
To turn OFF the receiver, press and hold the power button for more than three and less than 10 seconds
(release the power button when the BATT LED blinks solid red). This delay prevents the receiver from
being turned OFF by mistake.
Using Internal and External Power S ources
The receiver is powered by the internal battery or an external power source connected to the Micro-AB
USB port. If an external power source is connected, the receiver draws power from it in preference to
the battery.
Using a standard Micro-AB USB cable, you can connect the receiver to an external power source with
4.5–5.5 VDC to operate the receiver. See “Specifications” on page 45.
Internal Battery
The receiver first draws power from a connected external power source. When there is no valid external
power source connected or if the source has discharged to a voltage value less than 4.5V, the receiver
will draw its power from one high-capacity internal battery (non-removable)
.
The receiver will draw a small amount of power from the battery when it is turned off. If the
receiver is placed in storage for a long period, such as a few months, the battery may
become fully discharged. You will need to use an external power supply or recharge the
battery before use.
Power input greater than 6 VDC could damage the receiver.
Depending on use, the hours of operation provided by the internal battery varies. See
Table 9.
The GCX3 internal battery will slowly discharge over time, even if the receiver is powered
off. It is highly recommended that the GCX3 be fully charged shortly before each use.
