IMPORTANT NOTES

D When using the GPS receiver

• GPS signals cannot pass through metal objects. When us-
ing the ID-51A or ID-51E inside a vehicle, you may not re-
ceive GPS signals. We recommend you use it near a win-
dow. Please avoid the areas shown in the following:
1. DO NOT use where it will block the driver's view.
2. DO NOT use where the air bags could deploy.
3. DO NOT use where it becomes a driving obstacle.
• The Global Positioning System (GPS) is built and operated
by the U.S. Department of Defence. The Department is re-
sponsible for accuracy and maintenance of the system. Any
changes by the Department may affect the accuracy and
function of the GPS system.
• When the GPS receiver is activated, please do not cover
the ID-51A or ID-51E with anything that will block the satel-
lite signals.
• The GPS receiver may not work if used in the following loca-
tions:
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 malfunc-
tion.

D Spurious signals

Depending on the combination of the operating band and
mode, the Dualwatch or Triple-watch operation may generate
certain spurious signals, or noise may be heard. These do not
indicate a transceiver malfunction.

D About charging at power ON

ID-51A/E's charging circuit charges the supplied battery pack
in approximately 3 hours. But with this rapid circuit, the bat-
tery pack cannot be charged at power ON, by default. So, be
sure to turn OFF the power before charging.
When "Charging (Power ON)"* is set to ON in the MENU screen,
the battery pack can be charged even if the power is ON. (Only
when the battery pack is attached, and the optional CP-12L,
CP-19R or OPC-254L external DC power cable is connected
to [DC IN].) But this operation may generate certain spurious
signals; the S-meter appears, or noise may be heard.
*MENU > Function > Charging (Power ON) (Default: OFF)
• Charging time period at power ON may differ, depending on the
operating condition.
• The external DC power supply voltage must be between 10–16 V,
and the current capacity must be more than 2.5 A to charge the
battery pack when operating.
• When you operate the transceiver while charging, and if you cannot
receive signals correctly, set "Charging (Power ON)"* to OFF, and
disconnect the external DC power cable from [DC IN].
