General Installation-Cont.
POW3.5 Battery Connection
Because the POWV3.5 is an auxiliary power source to provide a jump-start assist, it must be connected parallel with the vehicle’s battery to operate.
The ground connection should provide a low resistance path to the chassis (if the vehicle has a negatively grounded chassis) or negative vehicle battery
terminal. Similarly, the positive connection should provide a low resistance electrical connection to the positive vehicle battery terminal. The gauge of
cable to be used is dependent on the distance from the POWV3.5 to the vehicle’s battery (See Wire Gauge/Distance Guide). In order to allow high
currents to pass, no fuse should be used in the electrical path.

Warning:
Improper installation will void the warranty.
System test
Once Installed, the POWV3.5 wakes up. The Status indicator will be slow flashing green light. This will indicate all connections are good and ready for
use. If the GO/STATUS button is pushed once the Battery level and temp lights will show current status.
If the POWV3.5 has connections errors the status indicator will blink red. Check all connections.

SYMPTOM
REMEDY
Unit does not wake upon button press
Internal battery may be discharged below operable level. Run motor or drive for at least one hour and check again. Unit
will not operate if not properly installed and connected electrically to the vehicle battery. The positive (red wire) must be
electrically connected to the positive terminal of the vehicle battery and the negative (black) wire must be electrically
connected to the negative battery terminal. The vehicle battery must be properly installed into the vehicle and connected
properly to the vehicle’s ignition system. If you suspect these conditions are not met, please consult with your installation
professional or a qualified vehicle mechanic to verify proper installation.
Unit will not activate upon button hold or
via mobile app
Make sure unit is awake before attempting to activate it as indicated by the STATUS indicator flashing green slowly. If
unit is not awake, press the GO/STATUS indicator or activate using the VOXX Power Systems mobile application. Unit will
not activate if certain error conditions exist which will be indicated by the STATUS indicator flashing red rapidly and one
or more active indicators. If the internal battery is too hot for use because of the environmental temperature or due to
a large number of jump-start attempts, the TEMP indicator will illuminate red until the internal battery has cooled to
an acceptable temperature. If ambient environment around unit is hot, try improving air circulation by opening doors,
windows or trunk in areas surrounding unit. If the battery charge level is too low to support additional jump-starts, the
far-left LED of the BATTERY indicator will flash.
Unit will not connect to mobile device
Make sure current version of mobile app in installed on mobile device. Make sure Bluetooth is activated on mobile
device.
After unit is activated, car will not start
The POWV3.5 provides a pre-charge function that charges the vehicle battery prior to starting which assists the
jump-start process and enables successful jump starts under circumstances where other jump-starters would fail.
Unit will not charge
The unit charges automatically when the internal battery level drops about 10% from its full charge and when the engine
is running as indicated by a voltage of at least 13V being provided by the alternator. If the alternator is not functioning
properly, the unit will not charge.
