INSTRUCTION MANUAL VHF AIR BAND TRANSCEIVER iA23 iA5 This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FOREWORD CAUTION READ ALL INSTRUCTIONS carefully and completely R WARNING! NEVER hold the transceiver so that the before using the transceiver. 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 5 to 10 cm away from the lips and the transceiver is vertical. SAVE THIS INSTRUCTION MANUAL— This instruction manual contains important operating instructions for the IC-A23/A5. R WARNING! NEVER operate the transceiver with a EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. WORD DEFINITION Personal injury, fire hazard or electric shock RWARNING may occur. CAUTION NOTE NEVER connect the transceiver to an AC outlet or to a power source of more than 14 V DC. Such a connection will damage the transceiver. Equipment damage may occur. Inconvenience only. No risk of personal injury, fire or electric shock. FCC caution: Changes or modifications to this transceiver, not expressly approved by Icom Inc., could void your authority to operate this transceiver under FCC regulations. (U.S.A. only) headset or other audio accessories at high volume levels. Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the volume level or discontinue use. NEVER connect the transceiver to a power source that is DC fused at more than 5 A. Accidental reverse connection will be protected by this fuse, higher fuse values will not give any protection against such accidents and the transceiver will be ruined. NEVER short the terminals of the battery pack. Also, current may flow into nearby metal objects, such as a necklace, SUPPLIED ACCESSORIES etc. Therefore, be careful when carrying with, or placing near metal objects, carrying in handbags, etc. DO NOT allow children to play with any radio equipment containing a transmitter. DO NOT operate the transceiver near unshielded electrical blasting caps or in an explosive atmosphere. AVOID using or placing the transceiver in direct sunlight or in areas with temperatures below –10°C (+14°F) or above +60°C (+140°F).

The duplex function requires frequency programming for the flight service station in advance. ◊ Programming a duplex frequency q Push [CLR] to select frequency mode. w Set a NAV band frequency using the tuning dial or keypad. • NAV band frequency range: 108.00–117.975 MHz e Push , then [5 (DUP-W)]. • “DUP” flashes and transmit frequency appears. r Set the frequency of the flight service station using the tuning dial or keypad. When using the tuning dial, push [ENT] after setting a frequency. ◊ Operating the duplex function q Set the desired frequency in NAV band. • NAV band frequency range: 108.00–117.975 MHz w Push , then [6 (DUP)] to turn the duplex function ON. • “DUP” appears on the function display. e Push and hold [PTT] to transmit at the pre-programmed transmit frequency. r Release [PTT] to return to receive. t Push , then [6 (DUP)] to cancel the function. A duplex frequency can be programmed into each memory channel independently. Set a duplex frequency before programming the memory channel, if desired. The duplex ON/OFF setting can also be programmed into a memory channel. • The displayed frequency returns to the NAV band frequency. EXAMPLE: Programming 123.65 MHz as the transmit frequency in the duplex function. 24 BATTERY PACKS ■ Charging precautions ■ Battery pack charging NEVER connect two or more chargers at the same time. The BP-200L BATTERY PACK includes rechargeable Ni-MH batteries and can be charged approx. 300 times. Charge the battery pack before first operating the transceiver or when the battery pack becomes exhausted. Charging may not occur under temperatures of 10°C (+50°F) or over temperatures of 40°C (+104°F). When using BC-119: If the charge indicator flashes orange, vehicle battery voltage is low and charging is not possible. 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. If you want to be able to charge the battery pack more than 300 times, the following points should be observed: 1. Avoid overcharging. The charging period should be less than 48 hours. 2. Use the battery until it becomes almost completely exhausted under normal conditions. We recommend battery charging just after transmitting becomes impossible. D Rapid charging with the BC-119 The optional BC-119 provides rapid charging of battery packs. One AD-87 and an AC adapter (may be supplied with the BC-119 depending on version) are additionally required. q Fix the optional AD-88 TERMINAL PC BOARD FOR CHARGER into the BC119 with the 4 supplied screws. w Insert the optional AD-87A* CHARGE ADAPTER into the charging slot of the BC-119. e Insert the optional AD-87B* CHARGE ADAPTER into the AD-87A* CHARGE ADAPTER. r Insert the battery pack, either by itself or attached to the transceiver, into the whole assembly for charging. (p. 26) *AD-87A and AD-87B supplied together named as AD-87. • Charging period: 2 hours 25 7 BATTERY PACKS D Rapid charging with the 119 D Regular charging q Attach the battery pack to the transceiver. w Be sure to turn the transceiver power OFF. e Connect the Wall charger (BC-110A) or optional cable (CP-12L or OPC-254L) as shown below. • Charging period: 10 hours Check orientation for correct charging *AD-87B (supplied with AD-87A) IC-A23/A5 with attached battery case AD-87A (optional) AD-88 (optional) BC-119 (optional) 26 CP-12L (optional) OPC-254L (optional) white To [CHARGE] black To a 12 to 14 V DC power source Wall charger BATTERY PACKS ■ About the battery pack D Operating period The operating period of the transceiver is 6 hours. • Operating periods are calibrated for the following conditions: at 25°C (77°F), Tx (high power) : Rx : standby = 5 : 5 : 90 D Battery pack life If your battery pack seems to have no capacity even after being fully 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 very little), a new battery pack must be purchased. ■ Battery pack CAUTION ● NEVER short the terminals of the battery pack. Also, current may flow into nearby metal objects, such as a necklace, etc. Therefore, be careful when carrying with, or placing near metal objects, carrying in handbags, etc. ● Keep battery contacts clean. It’s a good idea to clean battery terminals once a week. 27 8 CLONING Cloning allows you to quickly and easily transfer the programmed contents from one transceiver to another transceiver, or, data from PC to a transceiver using the optional CS-A23 cloning software. D Transceiver to transceiver cloning q Connect the OPC-474 CLONING CABLE with adapter plugs to the [SP/MIC] jack of the master and slave transceivers. • The master transceiver is used to send data to the slave transceiver. w While push and holding [Y] + [Z],push [PWR] ON to enter cloning mode (for both the master transceiver and slave transceiver both.). • “CLONE” appears and the transceivers enter the clone standby condition. e Push [PTT] on the master transceiver. • “CL-OUT” appears in the master transceiver’s display. • “CL-IN” appears automatically in the slave transceiver’s display. r When cloning is finished, turn power OFF, then ON again to exit cloning mode. 28 D Cloning using PC Data can be cloned to and from a PC (IBM compatible) using the optional CS-A23 CLONING SOFTWARE and the optional OPC478 CLONING CABLE. Consult the CS-A23 CLONING SOFTWARE HELP message for details. D Cloning error NOTE: DO NOT push [PTT] on the slave transceiver during cloning. This will cause a cloning error. When the display at right appears, a cloning error has occurred. In this case, both transceivers automatically return to the clone standby condition and cloning must be repeated. 9 TROUBLESHOOTING If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center.
