7 3 BASIC OPERATION Dial select functionUse the dial select function to adjust the tuning behavior of the [Y]/[Z] keys—use 1 MHz tuning when you want to change the frequency in large increments; use regular tuning when you want to change the frequency in smaller incre- ments. qPush [V/M] to select VFO mode. wPush [V/M] for 2 sec. one or more times to select the de- sired tuning increment. - 1 MHz tuning, 100 kHz tun- ing or regular tuning steps can be selected. (see dia- grams at right) ePush any key to return to nor- mal operation. NOTE: Large tuning steps should be used only when you want to change the frequency in large increments please se- lect regular tuning steps for normal operation. 1 MHz tuning selected 100 kHz tuning selected Regular tuning selected IC-A4#01 IM 01.12.5 5:14 PM Page 7 (1,1)

11 6 OTHER FUNCTIONS Initial set modeInitial set mode is accessed at power ON and allows you to set seldom-changed settings, in this way you can “customize” transceiver operations to suit your preferences and operating style.DEntering initial set modeqWhile pushing [V/M] + [ ],turn power ON. • The transceiver enters initial set mode and “mn”, “bP” or “St” ap- pears on the display. wPush[Y] or [Z] one or more times to select the desired item as described below and at right. ePush [ ] to select the desired condition. rPush [MW] or [PTT] to exit initial set mode and select the previous operating mode.DMemory namesThis item allows you to display a memory name instead of fre- quency. • When a memory channel has not been programmed with a name, frequency indication ap- pears instead. DBeep tones ON/OFFConfirmation beep tones nor- mally sound when you push a key. These can be turned ON or OFF as you prefer.DSide tones ON/OFFWhen using an optional headset such as those from the David Clark Co. via the adapter, the transceiver outputs your trans- mitted voice to the headset for monitoring.•Optional OPC-752HEADSET ADAPTER is required . Resetting the CPUReset the CPU before operating the transceiver for the first time, or when the internal CPU malfunctions. ➥While pushing [V/M] + [MW] + [SCAN], turn power ON to reset the transceiver. • “CLEAR” appears briefly to indicate the CPU has been reset. ] IC-A4#01 IM 01.12.5 5:14 PM Page 11 (1,1)
Charging precautionsNEVER attempt to charge dry cell bat- teries. This will cause internal liquid leakage and damage the battery case and transceiver. NEVER connect two or more chargers at the same time. Charging may not occur under temper- atures of 10°C (50°F) or over tempera- tures of 40°C (104°F). When using BC-119:If the charge indicator flashes orange, vehicle bat- tery voltage is low and charging is not possible. Check the vehicle bat- tery voltage in this case. If the charge indicator flashes red, there may be a problem with the battery pack (or charger). Re-insert the bat- tery pack or contact your dealer. Battery pack chargingThe BP-195 or BP-196 BATTERY PACK includes rechargeable Ni-Cd batteries and can be charged approx. 300 times. Charge the battery pack before first op- erating the transceiver or when the bat- tery pack becomes exhausted. If you want to be able to charge the bat- tery pack more than 300 times, the fol- lowing points should be observed: 1. Avoid overcharging. The charging pe- riod should be less than 48 hours. 2. Use the battery until it becomes al- most 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-81 and an AC adapter (may be supplied with the BC-119 depending on version) are additionally required.• Charging periods: 1.5 hours (w/BP-195) 2 hours (w/BP-196) 12 7 BATTERY PACKS Turn power OFF.

13 7 BATTERY PACKS DMultiple charging with the BC-121 The optional BC-121 allows up to 6 battery packs to be charged simultaneously. Six AD-81’s and an AC adapter (may be supplied with the BC-121 depending on version) are additionally required. •Charging periods: 1.5 hours (w/BP-195) 2 hours (w/BP-196) DRegular chargingqAttach the battery pack to the transceiver. wBe sure to turn the transceiver power OFF. eConnect the AC adapter (BC-110A/D/V) or optional cable (CP-12L or OPC-254L) as shown below. •Charging periods: 10 hours (w/BP-195) 15 hours (w/BP-196)IC-A4 with attached battery case (pack) BC-110A/D/V CP-12L (optional) OPC-254L (optional) To a 12 to 16 V DC power source To [CHARGE] white black M U L T I-C H A R G E R AC adapter (not supplied with some versions) Charge indicator (each indicator function independently) IC-A4#01 IM 01.12.5 5:14 PM Page 13 (1,1)
14 7 BATTERY PACKS About the battery packDOperating periodDepending on the attached battery pack, the operating period of the transceiver varies. Refer to the last page for battery pack specifications.DBattery pack lifeIf 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.DRecycling information (U.S.A only) The product that you have purchased may contain a rechargeable battery. The battery is recyclable. At the end of its life, under var- ious state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Call 1-800-8-BATTERY for battery recycling options in your area or contact your dealer. Installing batteries in the battery caseWhen using a battery case, install 8 AA (R6) size Ni-Cd or al- kaline batteries as illustrated below. qRemove the bat- tery case from the transceiver. wInstall 8 ×AA (R6) size Ni-Cd or alka- line batteries. •Be sure to observe the correct polarity. NEVERconnect DC power to the transceiver when in- stalling dry cell or alkaline batteries. Such a connection will damage the transceiver. Be careful of battery overcharging. When operating via ex- ternal DC power, installed batteries are simultaneously charged. Keep battery contacts clean. It’s a good idea to clean bat- tery terminals once a week.

CLONING 15 8 Cloning allows you to quickly and easyly transfer the programmed contents from one transceiver to another transceiver, or, data from PC to a transceiver using the optional EX-2119 cloning software.DTransceiver to transceiver cloningqConnect the OPC-474 CLONING CABLE with adapter plugs to the [SP] jack of the master and slave transceivers. •The master transceiver is used to send data to the slave trans- ceiver. wWhile pushing [Y] + [Z] + [V/M], turn power ON to enter cloning mode (master transceiver only—power ON only for slave transceiver). •“CLonE” appears and the transceivers enter the clone standby condition. ePush [PTT] on the master transceiver. •“CLoUt” appears in the mas- ter transceiver’s display. •“CL in” appears automati- cally in the slave trans- ceiver’s display. eWhen cloning is finished, turn power OFF, then ON again to exit cloning mode. DCloning using PCData can be cloned to and from a PC (IBM compatible) using the optional EX-2119 CLONING SOFTWARE and the optional OPC- 478 CLONING CABLE . Consult the EX-2119 CLONING SOFTWARE HELP message for details. DCloning error NOTE: DO NOTpush [PTT] on the slave transceiver dur- ing cloning. This will cause a cloning error. When the display at right ap- pears, a cloning error has oc- curred. In this case, both transceivers automatically return to the clone standby condition and cloning must be repeated. ] IC-A4#01 IM 01.12.5 5:14 PM Page 15 (1,1)
