PRECAUTION- continued USE the optional AC adapter or cigarette lighter cable only for both operating the transceiver and charging the battery. Other manufacturer's AC adapter, cigarette lighter cable or DC power cable with external power supply may damage the transceiver. Place the unit in a secure place to avoid inadvertent use by children. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below -4˚F (-20°C) or above +122˚F (+50°C). The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty. Even when the transceiver power is OFF, a slight current still flows in the radio. Remove the alkaline cells or battery pack from the transceiver when not using it for a long time. Otherwise, the installed batteries will become exhausted. FCC WARNING: NEVER open the transceiver's case to make any internal adjustments, changes or modifications by a person who not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations. Any transceiver's adjustments, replacement must be made by a qualified technician using the proper test equipment. iv
