SAFETY TRAINING INFORMATION Your Icom radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational Use Only”, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is W ARN ING NOT intended for use by the “General Population” in an uncontrolled environment. This radio has been evaluated for compliance at the distance of 2.
IN CASE OF EMERGENCY RECOMMENDATION If your vessel requires assistance, contact other vessels and the Coast Guard by sending a distress call on Channel 16. CLEAN THE TRANSCEIVER THOROUGHLY WITH FRESH WATER after exposure to saltwater, and dry it before operation. Otherwise, the transceiver's keys, switches and controllers may become unusable due to salt crystallization. ❍ USING CHANNEL 16 DISTRESS CALL PROCEDURE 1. “MAYDAY MAYDAY MAYDAY.” 2. “THIS IS ...........................
FOREWORD FEATURES Thank you for purchasing this Icom radio. The IC-M34 VHF MARINE TRANSCEIVER is designed and built with Icom’s state of the art technology and craftsmanship. With proper care this radio should provide you with years of trouble-free operation. Built tough to withstand the punishing marine environment, the IC-M34’s submersible construction meets IPX7 of the corresponding International Standard IEC 60529 (2001) while using BP-251 (option) or BP-252.
PRECAUTIONS RWARNING! NEVER connect the transceiver to an AC outlet. This may pose a fire hazard or result in an electric shock. RWARNING! NEVER hold the transceiver so that the antenna is closer than 2.5 cm (1 inch) from 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 (2 to 4 inches) away from the lips and the transceiver is vertical.

4 BASIC OPERATION ■ Channel selection IMPORTANT!: Prior to using the transceiver for the first time, the battery pack must be fully charged for optimum life and operation. To avoid damage to the transceiver, turn the power OFF while charging. D Channel 16 Channel 16 is the distress and safety channel. It used for establishing initial contact with a station and for emergency communications. Channel 16 is monitored during both Dualwatch and Tri-watch. While standing by, you must monitor Channel 16.
BASIC OPERATION 4 D U.S.A., International and Canadian channels D Weather channels The IC-M34 is pre-programmed with 59 U.S.A., 59 International and 63 Canadian channels. These channel groups may be specified for the operating area. The IC-M34 has 10 pre-programmed weather channels. These are used for monitoring broadcasts from the NOAA (National Oceanic and Atmospheric Administration). q Push [CH/WX] to select a regular channel.

BASIC OPERATION 4 ■ Call channel programming ■ Adjusting the volume level Call channel is used to access Channel 9 (default), however, you can program the call channel with your most often-used channels in each channel group for quick recall. Y]/[Z Z]. The volume level can be adjusted with [VOL] and [Y q Push and hold [U/I/C] (CH/WX) for 1 sec. several times to select the desired channel group (U.S.A., International or Canada) to be programmed. (p. 9) w Push and hold [9] (16) for 1 sec.
4 BASIC OPERATION ■ Adjusting the squelch level ■ Lock function Y]/[Z Z] keys as To adjust the IC-M34’s squelch level, use the [Y described below. In order to receive signals properly, as well as for the scan to function effectively, the squelch must be adjusted to the proper level. This function electronically locks all keys (except for [PTT], Y]/[Z Z]*) to [SQL•MONI], [VOL•MUTE], [H/L•LOCK] and [Y prevent accidental channel changes and function access. Y]/[Z Z].
BASIC OPERATION 4 ■ Monitor function The monitor function opens the squelch. See p. 5 for details of the monitor key action. ➥ The monitor function activates while pushing and holding [MONI] (SQL). •“ 4 ” blinks and audio is emitted. Blinks while the monitor function is used. Push and hold ■ AquaQuake water draining function The IC-M34 uses a new technology to clear water away from the speaker grill: AquaQuake.
5 SCAN OPERATION ■ Scan types Scanning is an efficient way to locate signals quickly over a wide frequency range. The transceiver has priority scan and normal scan. In addition, the weather alert and auto scan functions are available for standby convenience. These functions can be activated simultaneously, depending on the setting in set mode. (pgs. 18, 19) Choose priority or normal scan in set mode. (p.
SCAN OPERATION 5 ■ Setting TAG channels ■ Starting a scan For more efficient scanning, set the desired channels as TAG channels or clear the TAG setting from unwanted channels. Channels that are not tagged will be skipped during scanning. TAG channels can be assigned to each channel group (U.S.A., International and Canada) independently. Set the weather alert function, priority scan function, scan resume timer and auto scan function in advance, using set mode. (pgs.
6 DUALWATCH/TRI-WATCH ■ Description ■ Operation Dualwatch monitors Channel 16 while you are receiving on another channel; Tri-watch monitors Channel 16 and the call channel while receiving another channel. Dualwatch/Triwatch is convenient for monitoring Channel 16 when you are operating on another channel. q Select Dualwatch or Tri-watch in set mode. (p. 19) w Select the desired channel. e Push and hold [DUAL] (SCAN) for 1 sec. to start Dualwatch or Tri-watch (depending on set mode setting).
SET MODE 7 ■ Set mode programming D Set mode operation Set mode is used to change the settings for 12 transceiver functions: beep tone function, weather alert function, priority scan function, scan resume timer, auto scan function, dual/triwatch function, monitor key action, automatic backlighting, LCD contrast setting, power save function, squelch sensitivity and low fix function*. q Turn power OFF. w While pushing [SQL], turn power ON to enter set mode. • “bP” appears.
7 SET MODE ■ Set mode items D Beep tone function “bP” Select the key touch beep sound from ON or US, or turn sound OFF. • US : The preset beeps (e.g. do, re, mi) sound • ON : A fixed beep sounds (default) • OFF: Silent operation D Priority scan function “Pr” The transceiver has 2 scan types— normal (OFF) and priority (ON) scans. Normal scan searches all TAG channels in the selected channel group. Priority scan searches all TAG channels in sequence while monitoring Channel 16.
7 SET MODE D Auto scan function “AS” D Monitor key action “Sq” The auto scan function starts the desired scan automatically when no signal is received, and no operation is performed for 30 sec. The monitor key opens the squelch temporarily. This key action contains PUSH (Pu) or HOLD (Ho) settings as shown below. Push • Pu (PUSH): After pushing [MONI] (SQL) for 1 sec., the squelch opens and emits audio. The squelch is held open while continuously pushing and holding [MONI] (SQL).
7 SET MODE D LCD contrast setting “LC” Set the LCD contrast level from High contrast or Low contrast. D Squelch sensitivity “SS” When this function is turned ON, rejection of noise is improved so that the squelch is not easily affected by noise. NOTE: The LCD contrast level between High contrast and Low contrast makes no difference indoors.
