the zBoost Mobile1 and the power
source.
• If using a DC power supply in your
vehicle, ensure the power supply is
properly inserted. Then check the 12 volt
power from the car socket and the fuse.
Replace the fuse if necessary.
• If using a power strip in a building,
ensure the power strip is plugged in and

Red light:
An red light indicates the zBoost
Mobile1 has powered down to protect the cell
tower . Separation between the zBoost Mobile1
and the Outside Antenna is important to
prevent oscillation (feedback), similar to when
a microphone is too close to a speaker. When
oscillation occurs, the zBoost Mobile1 shuts
down in order to prevent interference in the cell
tower.
If the light is red, move the Outside Antenna
farther away from the zBoost Mobile1. On a
vehicle, that usually means moving it farther
toward the back of the car. Remember to keep
the antenna at least 6 inches from any window
or sunroof.
In a building, move the location of the zBoost
Mobile1 farther from the window where the
antenna is mounted. Once you have separated
the Outside Antenna and the zBoost Mobile1,
reset the zBoost Mobile1 by disconnecting the
power and then reconnecting the power supply.
If the light is green, the zBoost Mobile1 is
working properly. If the red light is still on, move
the Outside Antenna farther away and repeat
the process.
Green light:
A green light indicates the zBoost
Mobile1 is working properly.
