SECTION IV PER-OPERATION BATTERY INSTALLATION When using Nickel-Cadmium power pack 1C-BP3: . The IC-BP3 is a rechargeable Nickel-Cadmium power pack, and it can be slipped onto or off the set very easily. 1t has a connector for a charger charge-current control circuit, reverse polarity protection circuit and charge indicator LED in its own pack. You can use the supplied wall charger or similar simple wall charger, or a car battery by using optional cable IC-CP1 for recharging.
you should use the charger only.) The charge indicator LED of the power pack is lit, which shows that the charger is working. Cigarette Lighter socket IC-BP3 OUTLET 4. It takes about 15 hours to charge the batteries completely. This charger is designed for 0.1C rate current), but charge for 15 hours in order to compensate for any unbalance of the batteries. You should charge the batteries for 15 hours when you have not used them for a long time or after buying them. Charge between 0°C and 40°C. o 6.
When using the alkaline power pack 1C-BP4: Place the power switch in the OFF position. Remove the power pack from the bot torn of the set by pushing the pack in the indicated direction while sliding the lock button upward. Separate the pack ° into two parts (chassis and case as follows: While sliding the lock button upward, push the pack in: the indicated direction. Press both sides of the pack. Push the chassis downward. The chassis holds six AA type batteries.
WHEN TO REPLACE BATTERIES (When using alkaline batteries) When the battery exhausting indicator is indicated during transmission. the batteries are exhausted, Use batteries of the same type, for mixed type might cause leakage. Replace worn batteries with a complete new set. If used with old batteries, the life of new ones might be shortened. Battery life is shortened more by transmitting than by receiving since several times more current is drawn durum transmission.
FOR OUTDOOR USE 1. Attach the supplied power pack. (Refer to "BATTERY INSTALLATION") 2. Attach the supplied hand strap.and belt clip through the fixture on the bony (as shown in the drawings.}. 3. Attach the flexible rubber antenna. ATTACHMENT OF HAND STRAP AND BELT CLIP e Attach the belt clip on the back cover with 2 resews supplied.

MEMORY WRITING To memorize a frequency (duplex mode, its frequency separation and tone number of the tone encoder (1C-04AT only), if any) into memory channel, set the desired frequency (and duplex mode, etc, if any) with the procedures described before. Then, while pushing the "FUNGI” key.
The memorized frequency can be recalled easily by pushing the “B" (MEMORY READ) key and the channel number key (described later). The set has 10 memory channels, memory channel 1 ~ Memory channel 0. There are some special channels as follows; M1 {memory channel 1) The frequency memorized in M1 can be recalled by just pushing the "D (CALL) key.
30 7. STARTING THE PROGRAMMED SCAN FUNCTION By pushing the “'C” (PS) key while depressing the 'FUN! key, the programmed scan is started. The programmed scan scans between the frequencies memorized in the memory channels 9 and 0. More detail is described later. MEMORY CHANNEL MODE 1. MEMORY READ To recall a frequency memorized in a memory channel, push the "B” (MR} key then a digit key of the same number as the memory channel which has memorized the desired frequency.
After this, the other memory channels can be recalled by just pushing the dsg|t key of the memory channel number. FOR EXAMPLE: Push key 4} Doily BESEEM | M9.38 | (Y4375 | EMBODY 0 BESS Each push or continuous push of the (DOWN)J key. decreases the memory channel number in order, and displays channel number and contents of each memory channel on the frequency display.
FOR EXAMPLE: Push ke {or depressing ' continuously) [ ) Di play MMES Y4580 | | M98 By pushing the “A” (CL) key, the MEMORY CHANNEL MODE is cleared and the set returns in the DIAL MODE. At this time the frequency (duplex mode and tone number. if any) displayed previously in the MEMORY CHANNEL MODE will be kept. in the MEMORY CHANNEL MODE, all secondary functions except the PRIORITY and LOCK functions are disabled. 2.
FOR EXAMPLE: Push key Daley GBS 346.65 PRIORITY FUNCTION This feature allows you to check on your favorite frequency. such as a local repeater or calling channel, for activity while operating on a dial frequency or memory channel. It allows you to check if the frequency is busy or empty. The following steps are taken to utilize the PRIORITY FUNCTION. 1. Memorize your favorite frequency into the meaty channel 1.
34 5. If the set is turned to transmit mode, during the priority function, the transmit frequency will be the operating frequency in the SIMPLEX mode, or its expecting transmit frequency in the DUPLEX mode. When returned to the receive mode, the priority function will be continued. 6. To clear the PRIORITY FUNCTION just push the “A” (CL) key. FOR EXAMPLE: When the contents of M1 are 445.68MHz and —5.0MHz duplex and desired operating frequency is 445.52MHz with —5.
SCANNING OPERATIONS The provides MEMORY SCAN and PROGRAMMED SCAN operations. 1. MEMORY SCAN This is to scan the al} ten memory chariness in order continuously. A Memorize ten desired frequencies into the memory channels 1 ~ 0 each. |f your desired frequencies are less than ten, we recommend you to memorize the same frequency into several memory channels, : To start the scan, just push the “C"” (MS) key, and the letter ”S“ is displayed above the MHz digit on the frequency display and the scan starts.
36 FOR EXAMPLE: Push key Di ply 508 | M49.38 | |[34EEs weed (In DIAL MODE) A | 2. PROGRAMMED SCAN This is used to scan between two desired frequencies, which are memorized in the memory channels and 0. A. Memorize the frequencies of the high edge and low. edge of the desired scanning range into the memory channels 9 and 0. Regardless of which channel the high edge frequency is memorized in; the scan starts from the frequency memorized in the memory channel 0.
While the SQUELCH is engaged, the squelch opening as a signal is received will stop the scanning automatically to lock onto the frequency. To resume the scan when the scan stops on a signal, push the "C” (MS) key and the displayed frequency changes one increment. If the new frequency is no signal the scan will resume. If the set is turned to transmit mode, during the scan function, the transmit frequency will be the frequency displayed on the frequency display at the moment.
.38 RECEIVING Make sure the VOLUME CONTROL and POWER SWITCH is in the OFF position, and before turning the power ON, confirm as follows: 1. Make sure the power pack is properly charged and attached to the set. 2. Make sure the supplied flexible antenna is properly set. When an external antenna is employed, make sure the coaxial line is of the correct impedance (50 obs) and is neither shorted nor opened, and is firmly connected to the antenna connector.
For frequency setting, memory channel operation and scan operation refer to the above chapters.: TRANSMITTING . Eor SIMPLEX operation, make sure neither nor " is displayed on the frequency display. displayed, the set is in the DUPLEX mode, so push the "# {UP) key then (DOWN) key to clear the DUPLEX function. For DUPLEX operation, set the frequency separation according to the repeater’s input/output frequencies. . 1# the lower output power (0.5 watts) is sufficient, push the RF POWER SWITCH in.
40 If you need a sub audible tone to access a repeater, set the tone number suitable for the repeater {IC-04AT only). Refer to the “SETTING TONE ENCODER FREQUENCY" on page 23. If you need MDT tones (the same tones as telephone dialing tones) to access a repeater or make auto-phone-patch, etc., push a digit key while depressing the PTT switch, then continue to push digit keys without depressing the PTT switch. After pushing a digit key, the transmit mode will be kept about one second. (IC-04AT only).
