User manual ICOM IC-A23 - Instruction Manual

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 READ ALL INSTRUCTIONS carefully and completely before using the transceiver. CAUTION R WARNING! 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 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. DEFINITION Personal injury, fire hazard or electric shock RWARNING may occur. CAUTION NOTE Equipment damage may occur. Inconvenience only. No risk of personal injury, fire or electric shock. WORD 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 an AC outlet or to a power source of more than 14 V DC. Such a connection will damage the transceiver. 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. 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) NEVER short the terminals of the battery pack. Also, current may flow into nearby metal objects, such as a necklace, i SUPPLIED ACCESSORIES etc. Therefore, be careful when carrying with, or placing near metal objects, carrying in handbags, etc. Accessories included with the transceiver: Qty. q Antenna ........................................................................... 1 w Belt clip............................................................................ 1 e Handstrap........................................................................ 1 r Battery pack (BP-200L)*.................................................. 1 t Wall charger* .................................................................. 1 · Carrying case (LC-147)* ............................................... 1 · HEADSET ADAPTER (OPC-967)* ............................... 1 * The battery pack, wall charger, HEADSET ADAPTER or carrying case may differ depending on version.

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. 7 s Battery pack charging 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. 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: 1.5 to 2 hours 25 7 BATTERY PACKS 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: 15 hours D Rapid charging with the BC-119 Check orientation for correct charging * IC-A23/A5 with attached battery case CP-12L (optional) *AD-87B (supplied with AD-87A) AD-87A (optional) OPC-254L (optional) white To [CHARGE] black To a 12 to 14 V DC power source AD-88 (optional) BC-119 (optional) Wall charger 26 BATTERY PACKS 7 s 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 : 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. s Battery pack CAUTION q 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. q Keep battery contacts clean. It's a good idea to clean battery terminals once a week. 27 8 CLONING NOTE: DO NOT transfer the data from IC-A23 to IC-A5, when the data contains the NAV band data. In such case, cloning error may occur. Cloning allows you to quickly and easily transfer the programmed data 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. Cloning using PC Data can be cloned to and from a PC (IBM compatible) using the optional CS-A23 CLONING SOFTWARE and the optional OPC-478 CLONING CABLE. Consult the CS-A23 CLONING SOFTWARE HELP message for details. 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 [ENT] 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 error NOTE: DO NOT push [ENT] 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. TROUBLESHOOTING If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center. 9 REF. PROBLEM No power comes on.
