Important Notes; D Spurious Signals - Icom ID-31E PLUS Basic Manual

IMPORTANT NOTES

D When using the GPS receiver
• The GPS receiver is installed under the transceiver's top
panel. Therefore, when the GPS receiver is activated, do
not cover the top with anything that will block the satellite
signals.
• GPS signals cannot pass through metal objects. When
using the transceiver inside a vehicle, you may not receive
GPS signals. We recommend you use it near a window.
• The GPS receiver may not work if used in the following
locations:
1. Tunnels or high-rise buildings
2. Underground parking lots
3. Under a bridge or viaduct
4. In remote forested areas
5. Under bad weather conditions (rainy or cloudy day)
• The GPS receiver may not work if the transceiver operates
near the 440.205 MHz. This is due to signals made in
the internal circuit and does not indicate a transceiver
malfunction.
• The Global Positioning System (GPS) is built and operated
by the U.S. Department of Defense. The Department is
responsible for accuracy and maintenance of the system.
Any changes by the Department may affect the accuracy
and function of the GPS system.

D Spurious signals

When operating in the DV mode, you may hear some noises
around 430.080 MHz. These may be caused by spurious
signals generated in the transceiver's circuit but they do not
indicate a transceiver malfunction.
The GPS receiver is
installed here.
