IMPORTANT NOTES DDWhen using a GPS receiver • GPS signals cannot pass through metal objects. When using the ID-51A or ID-51E inside a vehicle, you may not receive GPS signals. We recommend you use it near a window. 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. • T he Global Positioning System (GPS) is built and operated by the U.S. Department of Defence. 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. • W hen the GPS receiver is activated, please do not cover the ID-51A or ID-51E with anything that will block the satellite signals. • T he 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) • T he 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. DDSpurious 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. DDAbout 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 battery 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. • T he 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. • W hen 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]. iv
