[. . . ] INSTRUCTION MANUAL UHF C. R. S. TRANSCEIVER i41S IMPORTANT READ ALL INSTRUCTIONS carefully and completely before using the transceiver. PRECAUTIONS R CAUTION!NEVER hold the transceiver so that the antenna is very close to, or touching exposed parts of the body, especially the face or eyes, while transmitting. The transceiver will perform best if the microphone is 5 to 10 cm away from the lips and the transceiver is vertical. SAVE THIS INSTRUCTION MANUAL -- This instruction manual contains important operating instructions for the IC-41S UHF C. R. S. NEVER operate the transceiver with a headset or other audio accessories at high volume levels. EXPLICIT DEFINITIONS DEFINITION Personal injury, fire hazard or electric shock RWARNING may occur. [. . . ] 13) · When the priority channel is not set, scan start channel is monitored during the priority scan. Appears 20 SCAN OPERATION 5 I Repeater search scan The repeater search scan is not only searching for a signal on the repeater channels, but also access a repeater by transmitting automatically in sequence. Thus the repeater search scan function searches an available repeater in the area even if the repeater is not in use. The repeater search scan detects a signal on the repeater output channels (CB-R1 to CB-R8) only. Therefore, repeater availability cannot be guaranteed even the repeater scan is stopped, because the scan will stop if any activity is detected. (The scan is cancelled when receiving a signal, such as stations communicating in simplex operation on a repeater output channel. ) q Select the desired repeater output channel (`CB-R1' to `CB-R8'), and push and hold (Rpt Scan) for 2 sec. to start the repeater search scan. · See the flow as described at right for repeater search scan details. Blinks Appears D Repeater search scan flow Scan start channel Scan Searches for signal on the repeater output channels. 5 Appears Access to the repeater automatically. (0. 5 sec. ) Wait for a signal from the repeater. (0. 5 sec. ) (When not reply signal is received. ) Access to the next repeater automatically. Scan w When receiving a signal on the repeater channel, scan stops. · During second cycle scanning, 3 high beeps sound when receiving a signal, and 3 low beeps sound when no signal receiving. e Push (Scan Mode) to cancel the scan manually. · During transmitting, the repeater scan cannot be cancelled. Scan is cancelled automatically. 21 6 TONE SQUELCH OPERATION I Tone squelch operation The transceiver is equipped with 51 CTCSS tone frequencies, 104 DTCS codes. CTCSS/DTCS operation provides communication with silent standby since you will only receive calls from group members using the same CTCSS tone frequency/DTCS code. NOTE: Channels 5 and 35 are used for the emergency channels, and CTCSS/DTCS operation is not available on these channels.
