[. . . ] INSTRUCTION MANUAL MF/HF MARINE TRANSCEIVER iM710RT IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver. SAVE THIS INSTRUCTION MANUAL--This manual contains important safety and operating instructions for the IC-M710RT MF/HF MARINE TRANSCEIVER. EXPLICIT DEFINITIONS The explicit definitions described below apply to this instruction manual. DEFINITION Personal injury, fire hazard or electric RWARNING shock may occur. WORD  NOTE: The IC-M710RTGMDSS version has a high-stability crystal oscillator unit. This unit draws a slight current even when power to the transceiver is OFF. [. . . ] When the selected channel is not in A1A mode, push [MODE] one or more times to select "A1A. " Operate the CW keyer to transmit a CW signal. keyer to the ACC(1) socket as shown at right. CW key 425 1 3 8 6 7 ACC(1) socket pin 2  NOTE: CW mode is not available in some versions and CW narrow can be selected in set mode (p. 14) when an optional filter is installed (already built-in to the GMDSS versions). pin 1 I FSK operation The transceiver has FSK and J2B modes for FSK operation--use FSK when using the built-in oscillator; use J2B when using an AFSK terminal unit. FSK terminal unit connection Connect an FSK terminal unit as shown at right. Push [MODE] one or more times to select the type of emission, "FSK" or "J2B. " Operate the FSK terminal unit. · FSK ITU channel group, ch 4001 to ch 25040, are available depending on version. pin 4 pins 2, 5 pin 3 FSK keying AF input Tx/Rx control Ground FSK terminal unit  NOTE: FSK shift frequency and FSK polarity can be adjusted in set mode (p. Some transceivers my operate 1. 7 kHz higher than the IC-M710RT's J2B mode even when the same displayed frequencies are in use. 425 1 3 8 6 7 ACC(1) socket I Cross channel operation* Cross channel operation is available with some versions to operate different channels for receive and transmit. Cross channel operation example ALM RX TX DSC DUP Select the desired channel for receive. Push [TX], then select the desired channel for transmit. · ITU simplex channels cannot be used. AGC F 2 3 4 A 0 1 While receiving ALM RX TX DSC Push [TX] again to stop the blinking. Change the channel to clear the cross channel setting. *This function is available for Europe versions only. · "$" flashes after pushing [TX]. DUP AGC F 2 3 4 A 0 1 While transmitting 11 5 USER CHANNEL PROGRAMMING I Programming a frequency The IC-M710RT has up to 160 user-programmable channels each with channel name capability of up to 7 alphanumeric characters.  NOTE: ITU simplex channels can be programmed as well as user channels. However, transmit frequencies cannot be programmed as it is not necessary. D Receive frequency Select the desired channel to be programmed. Enter the desired frequency via the keypad--5 or 6 digits. · "s" and frequency appear on the display. · Channels 1 to 160 (maximum) are programmable. Push [CE] ALM RX TX DSC DUP AGC F Frequency and "" appear. Set frequency ALM RX TX DSC DUP To change the operating mode (type of emission), push [MODE] one or more times. to program the user channel. Push and hold [RX] · Or rotate the [CHANNEL] selector to change the frequency. AGC F Use keypad or channel selector. ALM RX TX DSC DUP AGC F Programming is completed. D Transmit frequency (Not applicable for General versions) Select the desired user channel to be programmed. Push [TX]. Push [TX] ALM RX TX DSC DUP AGC F Push [CE] to select frequency selection mode. Enter the desired frequency via the keypad with 5 or 6 digits. · "s" and frequency appear on the display. · "$" flashes. "$" flashes. Push [CE] ALM RX TX DSC DUP AGC F Push and hold [TX] for 1 sec. Push [TX] to stop "$" from flashing. · The [CHANNEL] selector cannot be used. Push and hold [TX] after entering a frqeuency ALM RX TX DSC DUP AGC F D Channel names Select the desired user channel to be programmed. Rotate the [GROUP] selector for cursor position and the [CHANNEL] selector for name content. · The channel name (alphanumeric) readout flashes. Push [FUNC] then [CE] ALM RX TX DSC DUP AGC F "$" flashes. Rotate [GROUP] and [CHANNEL] to select cursor and character Push [RX] ALM RX TX DSC DUP Push and hold [RX] to program the name. · Flashing stops. · To return to the previous message, push [CE]. AGC F ALM RX TX DSC DUP AGC F 12 SET MODE I Set mode operation Set mode operation is used for programming infrequently changed values or conditions of functions. 6 NOTE: Some of the set mode items described in this section are not available on some transceiver versions. Push [POWER] to turn power off, if necessary. While pushing [FUNC] + [1], push [POWER] to turn Rotate the [GROUP] selector to select the desired item. Rotate the [CHANNEL] selector to set the values or conditions for the selected item. power on and enter set mode. [POWER] [FUNC] [1] ALM RX AGC TX DSC F Condition Item I Set mode contents (1) FSK ITU channels FSK ITU channels appear as a group between the ITU 25 MHz band and user channels. [. . . ] 13 DISPLAY Frequency cannot be set via the keypad. · The [CE] key is not pushed ("s" does not appear) before digit entry. · SITOR operation is set OFF in set mode. FSK ITU channels cannot be selected. 26 OPTIONS AND SPECIFICATIONS I Specifications GENERAL · Frequency coverage: Receive 500 kHz­29. 999 MHz Transmit 1. 6­ 27. 5 MHz · Mode: J3E (USB/LSB), H3E, J2B (AFSK), F1B (FSK), R3E, A1A (CW); available modes differ with version · Number of channels: 1136 channels (max. ) 160 user programmable, 242 ITU SSB duplex, 72 ITU SSB simplex, 662 ITU FSK duplex · Antenna impedance: 50 nominal · Usable temp. range: ­30°C to +60°C (­22°F to +140°F) · Frequency stability (­20°C to +60°C): 0. 5­14. 9999 MHz ±10 Hz 15­29. 9999 MHz ±20 Hz (GMDSS ±10 Hz) · Power supply requirement: 13. 6 V DC±15% (negative and floating grounds available depending on version) · Maximum current drain (at 13. 8 V DC): Main unit 30 A (transmit at max. audio) · Dimensions (projections not included): 9 TRANSMITTER · Output power: Below 25 MHz Above 25 MHz 150/60/20*1 W PEP 125 W PEP (GMDSS only*2) 60/20*1 W PEP 85 W PEP (GMDSS only*2) *1Except for Europe versions.
