‡
When using an external power cable longer than 5m
(15ft), it is recommended that positive voltage DC be
applied on both pins 3 and 4, and return on both pins
1 and 2
The optional Navcom P/N 82-020002-5001 Universal
AC/DC 12 V 2 Amp Power Adapter can be used to
supply DC voltage wherever an AC outlet is available for
the RT-3010 GPS receiver. Another optional external
power cable, NavCom
P/N 94-310060-3010 a 3m
(10ft) unterminated power cable fitted with a LEMO
plug type (Mfr. P/N FGG.1K.304.CLAC50Z) and red
strain relief, is suitable for supplying power to the RT-
3010
GPS sensor. The wiring color code and pin
designations are labeled on this optional cable
assembly.
The GPS sensor is protected from reverse polarity by an
inline diode. It will operate on any DC voltage between
10 and 30 VDC, capable of supplying the required
current, typically. Power Consumption of the RT-3010 is
typically 5 Watts Maximum.

Voltages less than 10VDC will shut the unit down.
When power is restored, the ON switch will need to be
held down for more than 3 seconds.

Voltages in excess of 30VDC will damage the unit. It
is extremely important to ensure that the power
supply is well conditioned with surge protection.
This is especially true for vehicular electrical systems,
which can create voltage spikes far in excess of
30VDC.
The RT-3010 comes equipped with 2 removable
Lithium Ion battery packs that provide secondary power
when the primary external voltage is not available. Each
