viewing window. The power
status light should be on

holder connected to battery
charger. Remove fuse and

Corrections
If possible, move the
PDN to a location with
better signal. If hardline/ISP
Internet is available connect
the Ethernet cable from said
hardline/ISP to WAN port.
Remove service cover to
ensure gateway power
cable is connected firmly
into back of gateway.
Replace the fuse with
a mini blade fuse of
same amperage
rating printed
on top of fuse.
Change the external DC
source or switch to a power
source with adequate
charge and voltage.
AC cable must be pressed
firmly and completely into a
live receptacle.
