Using an Auxiliary Power Source
In addition to the detachable batteries, you can connect the receiver to an external power source, such as a
vehicle battery with 9 to 21 VDC, to operate the receiver and for continuous use of the receiver if the detachable
batteries become discharged.
To connect the receiver to an auxiliary battery (Figure 15):
Use the alligator clips-to-SAE cable (p/n 14-008025-01) to directly connect the auxiliary battery and the
receiver’s power port (without SAE).
1. Connect the alligator clips-to-SAE cable to a 12-volt battery.
2. Connect the alligator clips-to-SAE cable to the receiver’s power port.
3. Turn on the receiver.
Figure 15: Connect an Auxiliary Battery and the Receiver
A single external 12 V, 2.3 A*h battery should run the receiver and modem for about 9 hours and the receiver
for 13 hours.
To connect the receiver to the charging cradle (Figure 16 on page 21):
The charging cradle with extra batteries hooks onto a tripod or belt for a convenient power supply for the
receiver. The part number for the receiver-to-charger cradle cable is 14-008072-02LF.
1. Connect one end of the cradle-to-receiver cable to the charging cradle.
Power input greater than 21 VDC could damage the receiver.
When powering the receiver using external batteries, set the charger mode to Off; otherwise, the
detachable batteries will also charge, causing operation time to decrease.
