INSTRUCTION MANUAL VHF/UHF ALL MODE TRANSCEIVER i910H 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-910H. EXPLICIT DEFINITIONS WORD DEFINITION R WARNING Personal injury, fire hazard or electric shock may occur. CAUTION NOTE Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, fire or electric shock. PRECAUTIONS R WARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. R NEVER apply AC to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver. R NEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] jack on the transceiver rear panel. This could cause a fire or ruin the transceiver. R NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This may result in an electric shock. R NEVER expose the transceiver to rain, snow or During mobile operation, DO NOT operate the transceiver without running the vehicle’s engine. When the transceiver power is ON and your vehicle’s engine is OFF, the vehicle’s battery will soon become exhausted. Make sure the transceiver power is OFF before starting the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiver and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. any liquids. BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods. AVOID using or placing the transceiver in areas with temperatures below –10°C (+14°F) or above +60°C (+140°F). Be aware that temperatures on a vehicle’s dashboard can exceed 80°C (+176°F), resulting in permanent damage to the transceiver if left there for extended periods. BE CAREFUL! If a linear amplifier is connected, set the transceiver’s RF output power to less than the linear amplifier’s maximum input level, otherwise, the linear amplifier will be damaged. AVOID placing the transceiver in excessively dusty environments or in direct sunlight. Use Icom microphones only (supplied or optional). Other manufacturer’s microphones have different pin assignments, and connection to the IC-910H may damage the transceiver. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. Versions of the IC-910H which display the “CE” symbol on the serial number seal, comply with the European harmonised standard ETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). Place unit in a secure place to avoid inadvertent use by children. 1 TABLE OF CONTENTS IMPORTANT ........................................ i EXPLICIT DEFINITIONS ..................... i PRECAUTIONS

Keep the shipping cartons. Select a location for the transceiver that allows adequate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna elements, radios and other electro-magnetic sources. For a description and a diagram of accessory equipment included with the IC-910H, see ‘Supplied accessories’ on p. 1 of this manual. The base of the transceiver has an adjustable stand for desktop use. Set the stand to depending on your operating conditions. ■ Grounding To prevent electrical shock, television interference (TVI), broadcast interference (BCI) and other problems, ground the transceiver through the GROUND terminal on the rear panel. For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distance between the [GND] terminal and ground as short as possible. R WARNING: NEVER connect the [GND] terminal to a gas or electric pipe, since the connection could cause an explosion or electric shock. ■ Antenna connection For radio communications, the antenna is of critical importance, along with output power and sensitivity. Select antenna(s), such as a well-matched 50 Ω antenna, and feedline. 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for your desired band.

The transceiver accepts data speed of up to 9600 bps. When using 9600 bps, set the transceiver to the 9600 bps data mode using the general set mode. (p. 57) When operating AFSK, connect external equipment to the DATA (MAIN or SUB) or ACC socket on the rear panel, or to the microphone connector on the front panel as in the diagram below. OPERATION NOTES FOR 9600 bps • Set the transceiver to 9600 bps data mode. - See p. 57. • Set AFSK/GMSK output level of the terminal unit to 0.4 V p-p (0.2 V rms). - When exceeding 0.5 V p-p (0.25 V rms), the transceiver’s modulation limiter stops modulation. - At this time, the [RX/TX] indicator’s brightness fades. • AF output from the transceiver is continuous and is not cut by the squelch circuit. ■ Connections for AFSK ◊ Connections via [DATA] socket Use FM mode for 9600 bps operation.

DATA COMMUNICATION ■ Operating mode notes ■ Operating frequency notes Use FM mode for 9600 bps operation. Use SSB or FM mode for 1200 bps operation. ◊ Operating notes for RTTY and AMTOR RTTY or AMTOR operating frequency in LSB mode differs from the displayed frequency. [Your operating freq.] = [Displayed freq.] – 2125 Hz (when the frequencies of the RTTY demodulator in your TNC or TU are — mark = 2125 Hz and space = 2295 Hz). ◊ Operating notes for PACKET PACKET operating frequency in LSB mode differs from the displayed frequency. [Your operating freq.] = [Displayed freq.] – 2125 Hz (when the frequencies of the PACKET demodulator in your TNC are — 2125 Hz/2315 Hz). ◊ Frequency setting example for AFSK - When operating RTTY at 144.090 MHz: Set “LSB 144.092125 MHz” (if you use mark=2125 Hz and space=2295 Hz). - When operating PACKET at 144.110 MHz: Set “LSB 144.112215 MHz” (if you use 2115 Hz/2315 Hz). ■ AFSK operation Connect external equipment to either the [DATA] (MAIN or SUB) or [ACC(1)] socket as described on the previous page. Set the ACC socket using the general set mode in advance when you operate via the ACC socket. (See below.) q Push [M/S•BAND] to select the desired frequency band. w Push [FM] or [SSB/CW] to select the desired operating mode. • LSB is normally used. • FM is used for PACKET. e Adjust the audio output level with [AF] control. • Use [RF/SQL] when required. r Adjust the desired RF output power. • When using the [MIC] connector for external equipment connection, the [MIC GAIN] control should be adjusted. t Select operating mode. y Control the transceiver from the connected PC or TNC (TU). qSelect band. wSelect desired mode. IMPORTANT: • Remove the microphone from the [MIC] connector when operating below 1200 bps rate to protect from noise coming from the microphone. • During 9600 bps rate operation, noise signals from the microphone may not effect PACKET signals. However, PACKET signal transmission is interrupted when [PTT] is pushed. • Remove the ACC plug, or turn the TNC power OFF during phone operation (SSB or FM). The modulation input from the [ACC(1)] socket is always applied to the modulation circuit. ◊ Connections via front panel When connecting a TNC or Scan converter, etc. to the [MIC] connector, [MIC GAIN] and [AF] adjustments are required. The [MIC] connector accepts up to 1200 bps. Use SSB or FM mode for operation. [MIC GAIN] and [AF] control adjustments are required. eAdjust for max. detected level. 53 9 DATA COMMUNICATION ◊ Adjusting the transmit signal output from the TNC When setting the data transmission speed to 9600 bps, the data signal coming from the TNC is applied exclusively to the internal limiter circuitry to control the transmission. NEVER apply data levels from the TNC of over 0.6 V p-p, otherwise the transceiver automatically cancels the transmission. 1. When using a level meter or synchroscope, adjust the TX audio output level (DATA IN level) from the TNC as follows. 0.4 V p-p (0.2 V rms): recommended level 0.2–0.5 V p-p (0.1–0.25 V rms): acceptable level 2. When NOT using a measurement device. q Connect the transceiver to a TNC. w Enter a test mode (“CAL”, etc.) to the TNC, then transmit some test data. e When the transceiver fails to transmit the test data or transmits sporadically (TX indicator does not appear or flashes): - Decrease the TNC output level until the transmit indicator lights continuously. When transmission is not successful even though the TX indicator lights continuously: - Increase the TNC output level. ■ Setting the ACC socket When operating AFSK, set the specifications of the ACC socket to fit your TNC or scan converter in advance. q Push [SET] for 1 sec. to enter the set mode. w Push [DN ▼] or [▲ UP] to select the 9600 bps data mode setting item, then rotate the tuning dial to turn the 9600 bps rate ON and OFF Push [SWP 0] again after setting. • “9600” is displayed. • 9600 bps data rate is selected when ON, and a slower data rate is selected when OFF is selected. • Push [M-CL 5] for 1 sec to return to the default setting. e Push [▲ UP] to select ACC socket pins 5 and 6 setting item, then rotate the tuning dial to select from “nor” (normal) and “Sub” (sub). • “ACC P5.6” is displayed. • When “nor” (normal) is selected, the ACC socket (pins 5 and 6) outputs MAIN band signals.
