[. . . ] NEVER short the terminals of the battery pack. NEVER connect the transceiver to a power source other than the BP-230, BP-231 or BP-232. Such a connection will ruin the transceiver. DO NOT push the PTT when not actually desiring to transmit. [. . . ] If the programmable function names are bracketed in the following explanations, the specific key used to activate the function depends on programming. SCAN A KEY This key's operation depends on the Power ON Scan setting. When the power ON scan function is turned OFF; Push to start and cancel scanning operation. In case of transmission during scan, cancels scanning. When the power ON scan function is turned ON; Push to pause scanning. Scanning resumes after passing a specified time period. In case of transmission during scan, pauses scanning. Scanning resumes after passing a specified time period. SCAN B KEY Push to start and cancel scanning operation. In case of transmission during scan, pauses scanning. Scanning resumes after passing a specified time period. This function can be used for situations other than an emergency alert such as a security alarm for example. TALK AROUND KEY Push to turn the talk around function OFF. Push and hold to turn the talk around function ON. · The talk around function equalizes the transmit frequency to the receive frequency for transceiver-to-transceiver communication. WIDE/NARROW KEY Push to select the IF bandwidth to wide. · The wide passband width can be selected from 25. 0 or 20. 0 kHz using the CS-F14 CLONING SOFTWARE (PMR operation only. ) Ask your dealer for details. Push and hold to select the IF bandwidth to narrow. 10 11 3 CONVENTIONAL OPERATION I Call procedure [VOL] CONVENTIONAL OPERATION 3 I Turning power ON Rotate [VOL] to turn power ON. When your system employs tone signalling (excluding CTCSS and DTCS), the call procedure may be necessary prior to voice transmission. The tone signalling employed may be a selective calling system which allows you to call specific station(s) only and prevent unwanted stations from contacting you. q Select the desired TX code channel or 2/5-tone code according to your System Operator's instructions. · This may not be necessary depending on programming. 3 I Channel selection IC-4GXA/F25S: Toggle [CHANNEL SWITCH] to select the channel 1 or 2, or, push one of [MRCH 1] to [MR-CH 4] key to select a channel directly. · The memory channels 3 and 4 are available when [MR-CH 3] and [MR-CH 4] keys are assigned. [CHANNEL SWITCH] w Push the call key (assigned to one of the dealer programmable keys. ) (p. 11) e After transmitting a 2/5-tone code, the remainder of your communication can be carried out in the normal fashion. Selective calling Non-selective calling IC-F15/F25: Rotate [CHANNEL SELECTOR] to select the desired operating channel, in sequence; or, push one of [MR-CH 1] to [MR-CH 4] key to select a channel directly. [CHANNEL SELECTOR] AUTOMATIC SCAN TYPE: Channel setting is not necessary for this type. When turning the power ON, the transceiver automatically starts scanning. Push and hold [Scrambler] to turn the scrambler function ON. Push [Scrambler] to turn the scrambler function OFF. I Man Down Emergency Call The man down emergency call function transmits an emergency call automatically, after the transceiver laying down in a horizontal position for a pre-set time period. (The optional UT-113 MAN DOWN UNIT is required. ) After the emergency call, the transceiver performs transmission and reception alternately with the following conditions: - Transmits the microphone signals. When the emergency cancel code is received, the function is cancelled. [. . . ] 3) e Pinch the clip (q), and slide the base clip in the direction of the arrow (w). q w 6 CAUTION: HOLD THE TRANSCEIVER TIGHTLY, WHEN HANGING OR DETACHING THE TRANSCEIVER FROM THE BELT CLIP. Otherwise the transceiver may not be attached to the holder or swivel properly if the transceiver is accidentally dropped and the base clip is scratched or damaged. 28 29 7 OPTIONS D BELT CLIPS OPTIONS 7 D BATTERY PACK · BP-230 Li-Ion BATTERY PACK 7. 4 V/800 mAh Li-Ion battery pack, allows approx. · BP-231 Li-Ion BATTERY PACK 7. 4 V/1150 mAh Li-Ion battery pack, allows approx.
