1. Try all sides of a building to see which side provides the strongest radio signal.
2. Move from under trees. Pine needles absorb radio signals more than leaves.
3. Move away from overhead electrical wires.
4. Radio signals reflect off other buildings. Even in the signal shadow, the signal could be reflected back by
another building.
5. Try not to hold the unit. If possible, place it in vehicle, on a cabinet or desk.
6. If holding the unit, turn the unit in 90-degree increments to avoid shielding it with your body.
7. The signal is 1-2 feet across; therefore, moving several feet in any direction may give different results.
Inside a Building
1. Move toward windows.
2. Signals do not penetrate ground; therefore, there will probably be no signal in basements.
3. Reflective coatings on windows reflect radio signals. Try the side of the building that is least likely to have
coated windows.
4. Closed metal blinds can reflect radio signals.
5. Dropped ceilings sometimes hide an accumulation of electrical cable.
Electromagnetic Interference (EMI)
1. Electromagnetic Interference (EMI) is generated by switching circuitry closets or Un-interruptable Power
Source (UPS) systems found near computer rooms and can block the radio signal.
2. Look for significant sources of electromagnetic radiation. The problem may emanate from a source between
location and the radio base station.
When to use Landline Communication
If these tips do not improve radio signal strength, switch to landline communication. Switching to landline
communication is faster than searching for and trying to improve the radio signal.
Operating with Battery Power
The computer operates on AC or battery power. This section contains the information you need to know to operate
the computer on battery power. It also includes information on how your computer manages and saves power.
