User manual ICOM IC-T31CP

[. . . ] The transceiver will perform best if the microphone is 5 to 10 cm (2 to 4 in) away from the lips and the transceiver is vertical. RWARNING!NEVER EXPLICIT DEFINITIONS The explicit definitions below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric shock RWARNING may occur. WORD operate the transceiver with a headset or other audio accessories at high volume levels. [. . . ] Connected voltage is over 16 V and could damage the transceiver. 3 6 0 after 2 sec. To change the frequency from the 100 kHz digit, push [·], then 3 digits. . 5 0 0 10 BASIC OPERATION 3 s Setting tuning steps D Via the keypad (other band directly) Push [VFO] to select VFO mode. USING SET MODE Push 6 digit keys, starting from the 100 MHz digit. · The operating band changes automatically. · It's not necessary to input the decimal point. 4 0 4 This transceiver has 8 tuning steps (VHF and UHF bands have independent settings) as follows: · 5 kHz · 10 kHz · 12. 5 kHz · 15 kHz · 20 kHz · 25 kHz · 30 kHz · 50 kHz Push [VFO] to select VFO mode. Push [(VFO)CLR] to exit set mode. For convenience, select a tuning step that matches the frequency intervals of repeaters in your area. 0 0 0 [DISPLAY EXAMPLE] D Other methods VIA THE DIAL: Rotate [DIAL] to change the frequency according to the set tuning steps. USING THE MHz STEP: Push [(VFO)MHz] for 1 sec. , then rotate [DIAL] to change the frequency in one MHz steps. 15 kHz tuning step 25 kHz tuning step 11 3 BASIC OPERATION s Selecting a memory channel Push [MR] to select memory mode. Push 2 digit keys to select the desired memory channel (or rotate [DIAL]). · The first nine memory channels are preceded by a "0. " · To select scan edges 1A to 4B, use [@] for "A" and [?] for "B. " · Only programmed memory channels can be selected. MR MR s Receive and transmit Push [POWER] for 1 sec. Adjust the [VOL] control to the desired level. · While pushing [MONI], rotate [VOL]. Set the squelch level. 6 MR · While pushing [MONI], rotate [DIAL]. · 4 selections are available, "OP" (open), "AT" (automatic), 1 and 2. Set an operating band and frequency. 0 MR When a signal is received: Squelch opens and audio is emitted from the speaker. The S/RF indicator shows the relative signal strength. Push [H/L] to toggle output power between high and low. · "LOW" appears when low output power is selected. Push and hold [PTT] to transmit; then speak into the mic. s Lock function The lock function prevents accidental frequency changes and accidental function activation. Slide [LOCK] up or down to set the lock function ON or OFF, respectively. · "L" appears while the lock function is activated. · [PTT], [POWER], [VOL], [MONI], and [H/L] can be used regardless of this setting. · Do not hold the microphone too close to your mouth or speak too loudly. · The S/RF indicator shows the output power selection. Release [PTT] to return to receive. CONVENIENT Monitor function: Push and hold [MONI] to listen to weak signals that do not open the squelch; or push [MONI] twice to monitor a signal without having to continuously hold [MONI]. 20) 4 D Programming during selection Push [VFO] to select VFO mode. Set the desired frequency: Set other data, such as repeater information, etc. · Do not hold [S. MW] for more than 1 sec. , otherwise the memory channel will overwrite the displayed number. L OW DUP DUP MR L OW DUP MR Rotate [DIAL] to select the desired channel. · Call channel and scan edge channels, as well as regular memory channels, can be programmed in this way. · If you want to confirm the VFO frequency, push [S. MW] momentarily. L OW DUP L OW Push [S. MW] for 1 sec. to program. · "X" stops flashing. 15 4 ADVANCED FUNCTIONS D Memory/call call/memory Select the memory/call channel to be transferred: Push [MR] (or [CALL]) to select memory (call) mode. Push [S. MW] momentarily. · A beep sounds, "VF" appears and "X" flashes. · Do not hold [S. MW] for more than 1 sec. , otherwise the memory channel will overwrite the VFO. D Programming after selection Select the memory channel to be programmed: Push [MR] to select memory mode. Rotate [DIAL] (or use the keypad) to select the memory channel. · Non-programmed channels cannot be selected. Set the desired frequency in VFO mode: Push [VFO] to select VFO mode. to program. Rotate [DIAL] to select a memory or call channel to transfer the data. Push [S. MW] for 1 sec. to program. · "X" stops flashing. D Memory/call VFO Select the memory/call MW D channel to be transferred: Push [MR] (or [CALL]) S. MW to select memory (call) for 1 sec. to transfer to VFO. DUP D Memory clear Push [S. MW] momentarily. [. . . ] While pushing [MR] + [VFO] + [BAND] turn power ON to reset the transceiver. CAUTION: Resetting the CPU returns all programmed contents to their default settings. 26 TROUBLESHOOTING If your transceiver seems to be malfunctioning, please check the following points before sending it to a service center. PROBLEM No power comes on. 6 REF. POSSIBLE CAUSE SOLUTION · The battery is exhausted. 7, (A slight current flows in the circuits even when teries in the battery case. 8 the power is OFF. ) (Remove the battery pack if you will not be using the transceiver for a long time. ) · Poor plug connection to the external DC power · Check the connector or remove and replace the -- cable.
