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. Push and hold to activate the connected output signal level. This function can be used for situations other than an emergency alert such as a security alarm for example. 11 3 CONVENTIONAL OPERATION I Turning power ON Rotate [VOL] to turn power ON. [VOL] I Channel selection IC-F15S/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] 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. Scanning stops when receiving a call. 12 CONVENTIONAL OPERATION 3 I Call procedure 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 w Push the call key (assigned to one of the dealer programmable keys. ) (p. Push and hold [Scrambler] to turn the scrambler function ON. Push [Scrambler] to turn the scrambler function OFF. I Setting the squelch level The squelch circuit mutes the received audio signal depending on the signal strength. q While pushing [PTT] and [Lower], rotate [VOL] to turn the power ON to enter the squelch level adjustment mode. w Push [Upper] to increase the [Upper] squelch level (tight squelch) or [PTT] [Lower] to decrease the squelch level (loose squelch). [. . . ] And insert the transceiver into the belt clip until the base clip inserted fully into the groove. 6 r Once the transceiver is locked in place, it swivels as illustrated below. 27 6 SWIVEL BELT CLIP I To detach q Turn the transceiver upside down in the direction of the arrow and pull out from the belt clip. 28 SWIVEL BELT CLIP 6 w Release the battery pack if it is attached. 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. 29 7 OPTIONS 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.
