FOREWORD
Thank you for purchasing the IC-3FGX 245 MHz FM transceiver. READ ALL INSTRUCTIONS carefully and completely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL–This instruction manual contains important operating instructions for the transceiver.
IMPORTANT
RCAUTION! NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 2 to 4 in. (5 to 10 cm) away from the lips and the transceiver is vertical.
RCAUTION! NEVER operate the transceiver with a headset or other audio accessories at high volume levels.
RCAUTION! NEVER short the terminals of the battery pack.
DO NOT push the PTT when not actually desiring to transmit.
AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below +14°F (–10°C) or above +122°F (+50°C).
DO NOT modify the transceiver for any reason.
KEEP the transceiver from the heavy rain, and Never immerse it in the water. The transceiver construction is water resistant, not water proof.
The use of non-Icom battery packs/chargers may impair transceiver performance and invalidate the warranty.

BATTERY PACKS 3
‘Battery cautions
•CAUTION! NEVER short terminals of the battery pack (or charging terminals of the transceiver). Also, current may flow into nearby metal objects such as a necklace, so be careful when placing battery packs (or the transceiver) in handbags, etc.
Simply carrying with or placing near metal objects such as a necklace, etc. causes shorting. This will damage not only the battery pack, but also the transceiver.
•NEVER incinerate used battery packs. Internal battery gas may cause an explosion.
•NEVER immerse the battery pack in water. If the battery pack becomes wet, be sure to wipe it dry BEFORE attaching it to the transceiver.
•Clean the battery terminals to avoid rust or miss contact.
•Keep battery contacts clean. It’s a good idea to clean battery terminals once a week.
If your battery pack seems to have no capacity even after being charged, completely discharge it by leaving the power ON overnight. Then, fully charge the battery pack again. If the battery pack still does not retain a charge (or only very little charge), a new battery pack must be purchased. (P. 9)

BC-119
When using the BC-119 in a vehicle: If the charge indicator flashes orange, the vehicle battery voltage is low and charging may not be performed. Check the vehicle battery voltage in this case. If the charge indicator flashes red, there may be a problem with the battery pack (or charger). Re-insert the battery pack or contact your dealer.
