INSTRUCTION MANUAL VHF TRANSCEIVER iV8 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.
SAFETY TRAINING INFORMATION CAUTION To ensure that your exposure to RF electromagnetic energy is within the FCC allowable limits, always adhere to the following guidelines: • DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also cause you to exceed FCC RF exposure limits. A proper antenna is the antenna supplied with this radio by the manufacturer or an antenna specifically authorized by the manufacturer for use with this radio.
• ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when transmitting, and only use the Icom belt-clips which are listed in this manual when attaching the radio to your belt, etc. To provide the recipients of your transmission the best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and slightly off to one side.
FOREWORD Thank you for purchasing the IC-V8 FM transceiver. This transceiver is designed for those who require quality, performance and outstanding reliability under the most demanding conditions.

3 BATTERY PACKS ‘ Battery pack replacement Before replacing the battery pack, push [POWER] for 1 sec. to turn the power OFF. • Push the battery release forward, then pull the battery pack upward with the transceiver facing you. D BATTERY PACKS Charging period Battery Voltage Capacity pack BC-146 Battery case for AA BP-208*2 (R6) × 6 alkaline BP-209 7.2 V BP-210 7.2 V BP-222 7.2 V 1100 mAh 1650 mAh 600 mAh BC-14 4 or BC-121 Operating period*1 N/A 12 hrs 1.5 hrs 7.5 hrs 18.5 hrs 2.
3 BATTERY PACKS ‘ Battery caution • CAUTION! NEVER short the 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.
BATTERY PACKS 3 ‘ Battery charging D Regular charging with the BC-146 Turn power OFF. Check orientation for correct charging. (Insert together with AD-99.) The optional BC-146 provides regular charging of an optional battery pack with/without transceiver. The following is additionally required: • An optional AC adaptor. (An AD-99 is supplied with BC-146.) BC-146 + AD-99 D About AD-99 Attach the spacer (Spacer B/C) to the adaptor (Spacer A) with orientation as illustrated in the diagram below.
3 BATTERY PACKS D Rapid charging with the BC-144 The optional BC-144provides rapid charging of optional battery packs. The following are additionally required: Turn power OFF. Check orientation for correct charging. (Insert together with AD-99.) • An AC adaptor (may be supplied with the BC-144 depending on version). BC-144 + AD-99 D Rapid charging with the BC-121+AD-94 (#11) The optional BC-121 allows up to 6 battery packs to be charged simultaneously. The following Turn power OFF.
BATTERY PACKS 3 ‘ Charging NOTE Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. • Recommended temperature range for charging: +10°C to +40°C (50°F to 140°F). • Use the supplied charger or optional charger (BC-144/BC-121 for rapid charging, BC-146 for regular charging) only. NEVER use other manufacturers’ chargers.
3 BATTERY PACKS ‘ Battery case (optional for some versions) When using a BP-208 BATTERY CASE attached to the transceiver, install 6 AA (R6) size alkaline batteries as illustrated below. D CAUTIONS • Use ALKALINE batteries only. • Make sure all battery cells are the same brand, type and capacity. • Never mix old and new batteries. Either of the above may cause a fire hazard or damage the transceiver if ignored. • Never incinerate used battery cells since internal battery gas may cause them to rupture.

10 PAGER/CODE SQUELCH ‘ Pager function Optional UT-108 required This function uses DTMF codes for paging and can be used as a “message pager” to confirm you of a caller’s identification even when you leave the transceiver temporarily unattended.
PAGER/CODE SQUELCH 10 ‘ Code programming Optional UT-108 required D Before programming The pager and code squelch functions require ID codes and a group code. These codes are 3-digit DTMF codes and must written into the code channels before operation. q Decide the ID code of each transceiver and a group code for your group. w Decide whether you want to return to normal operation or code squelch operation after a connection is made.
10 PAGER/CODE SQUELCH D Code programming An ID code MUST be programmed into code channel C0. Up to 6 transmit codes are programmable into code channels, C1 to C6, if required. q Push [✱•OPTION] after [A•FUNC] is pushed. F MR • Pager mode is selected. • 100 MHz digit shows “P.” w Push [8•SET] after [A•FUNC] is pushed. F MR • One of either “CP” or “C0” to “C6” flashes. • “C0” is the ID code and “C1” to “C6” are transmit codes. TX TX e Rotate [VOL] to select code channel C0.
PAGER/CODE SQUELCH 10 • Receive accept/receive inhibit ➥ “Receive accept” (“SKIP” indicator does not appear) accepts pager calls when the transceiver receives a signal with a code the same as that in the code channel. ➥ “Receive inhibit” (“SKIP” indicator appears) rejects calls even when the transceiver receives a code the same as that in the code channel. Transmit codes should therefore be programmed for “receive inhibit,” otherwise the transceiver will not reject unnecessary calls.
10 PAGER/CODE SQUELCH ‘ Pager operation Optional UT-108 required D Calling a specific station q Program the desired code channel in advance (p. 41). w Set the operating frequency. • Set the AF and squelch to the desired level as in normal operation. e Push [✱•OPTION] after [A•FUNC] is pushed. • Pager mode is selected. • 100 MHz digit shows “P.” F MR TX r Select the desired transmit code channel: ➥ Push [8•SET] after [A•FUNC] is pushed. ➥ Rotate [VOL] to select the desired code channel.
PAGER/CODE SQUELCH 10 D Waiting for call from a specific station q Set the operating frequency. w Push [✱•OPTION] after [A•FUNC] is pushed. • 100 MHz digit shows “P.” e Wait for a call. • When receiving a call, the caller’s ID or group code appears as shown below. • DO NOT push any digit keys while code channels C0 to C6 are displayed, or code channel contents will be changed. r Push [PTT] to send an answer back call and display the operating frequency.
10 PAGER/CODE SQUELCH ‘ Code squelch Optional UT-108 required Code squelch provides communications with quiet standby since you will only receive calls from stations which know your ID or group code. Each push of [PTT] sends a 3-digit code in order to open the receiving station’s code squelch prior to voice transmission. q Set the operating frequency. • Set the AF and squelch to the desired level as in normal operation. w Push [✱•OPTION] after [A•FUNC] is pushed. • Repeat several times, if necessary.
