SYNTHESIZED HAND HELD TRANSCEIVER The ICON IC-M12 is a very compact VHF synthesized hand held transceiver. Using the latest in electronic design, the IC-M12 offers diode programming for frequency selection, eliminating the need; expense and delay in changing the channel configuration. Channels are easily installed or changed, any time, at your marine dealer, by changing diode positions on the matrix board.

ACCESSORIES Carefully remove your transceiver from the packing carton and examine it for signs of shipping damage. Should any be apparent, notify the delivering carrier or dealer immediately, stating the full extent of the damage. It is recommended that you keep the shipping cartons. In the scent storage, moving, or reshipment becomes necessary, they come in handy. Various accessories are packed with the transceiver. Make sure you have not overlooked anything, 1.
SECTION [V PER-OPERATION BATTERY INSTALLATION When using Nickel-Cadmium power pack IC-CM3: The IC-CM3 is a rechargeable Nickel-Cadmium power pack, and it can be slipped onto or off of the set very easily. It has a connector for a charger charger-current control circuit, reverse polarity protection circuit and charge indicator LED in its own pack. You can use the supplied CM-25U/E wall charger or similar simple wall charger, or a 12V battery by using optional cable IC:CM1 for recharging.
Connect the output plug of the wall charger or other power source, to the charger socket of the power pack. (When charging Nickel-Cadmium batteries in the power pack, you should use the CM-30 charger only.}) The charge indicator LED of the power pack is lit, which shows that the charger is working. OUTLET oo It takes about 15 hours to charge the batteries completely. This charger is designed for 0.1C {10-hour rate current). but charge for 15 hours in order to compensate for any unbalance of the batteries.
PRECAUTIONS FOR USE OF THE BATTERIES (from the JIS C8705 MANUAL) General Cautions 1. Never short the power pack, Since internal resistance is low, excess shorted current flows away, causing the batteries or conductors to burn. Avoid shorts! A label showing polarity is on the power pack. Never solder the batteries directly. If the batteries are soldered directly, the separator or insulator may become melted and damaged. Accordingly, the terminal must be spot-welded first and then soldered.
When using the alkaline power pack 1-CM 4: Place the power switch in the OFF position. Remove the power pack from the bottom of the set by pushing the pack in the indicated direction. Separate the pack into two parts (cases) as follows: Each case holds three AA type batteries. Install batteries into each case, according to indicated polarity. With the batteries properly in place, carefully replace the pack and slip it onto the set with the reverse procedure.
WHEN TO REPLACE BATTERIES (When using alkaline batteries) When the Transmit Indicator LED does not light up during transmission, the batteries are exhausted, Use batteries of the same type, for mixed types might cause leakage. Replace worn batteries with a complete new set. If used with old batteries, the life of new ones might be shortened. Battery life is shortened more by transmitting than by receiving, since several times more current is drawn during transmission.
40— ATTACHMENT OF HAND STRAP AND BELT CLIP CHANGE OR ADDITION OF CHANNELS The design of your ICON Marine Radiotelephone provides an inexpensive means for expanding channel capability. The services of a dealers technician is required for installation and alignment. The additional channel(s) you require may be placed anywhere on the dial you choose. Additional weather channels can also be installed on the channels G, H.
LICENSES REQUIRED 1. Ship Station License Your craft, when equipped with VHF/FEM equipment, has a radio station on board which, if used, must have a current license. It is unlawful to operate a Ship Station which is not licensed. Inquire through your dealer or appropriate government agency for an application for a Ship Radio-Telephone license. Your craft station will be issued a call sign. 2.

SECTION. VI QPE RAT!ON RECEIVING Make sure the (5) VOLUME CONTROL and POWER SWITCH is in the OFF position, and before turning ON the power switch, confirm as follows: 1. Make sure the power pack is properly charged and attached to the set. Make sure the supplied flexible antennas properly set. When an external antenna is employed. make sure the coaxial line is of the correct impedance (80 ohms) and is neither shorted nor opened. and is firmly connected to the antenna connector.
If you wish to monitor one of the channels installed; simply rotate the Channel Select switch to the proper channel. If you wish to monitor the Weather channel, simply set the Channel Select switch to the weather (WX] channel (or the letter channel with weather channel installed). TRANSMITTING Set the controls and switches at the same positions as receiving. Rotate the Channel Select Switch until you find an empty channel that can be used for the type of communication you wish.: Be sure the channel is open.
g | SECTION VII OPERATING RULES AND GUIDELINES Prevent Interference Before transmitting, monitor the channel you wish to use to avoid interrupting transmissions in progress. Call Procedures Calls must be properly identified and time limits must be respected. 1. Give our call sign each time you place a call to another vessel or a coast station. (If a call sign has not been assigned, identify the station by announcing the vessel name and the name of the licenses.) 2.
False or fraudulent distress signals are prohibited and punishable by law! Privacy Information overheard but not intended for you cannot lawfully be used in any way. Indecent or profane language is prohibited. Logs Use of this equipment required entry of the watch period of 156.8MHz {CH 16) by the operator with vessel name, call sign and operator signature. All distress, emergency, and safety messages must be recorded in complete detail. Log date activity is usually recorded in 24 hour time.
=20 Channel usage A channel selection system, frequency-usage, has been internationally adapted for the marine VHF band. Each frequency within the spectrum has been assigned a channel number, for example. 156.300 is Channel 6. Specific purposes have been assigned to each channel under this system i.e. internship between two vessels and ship-to-shore. Geographical locations have specific channels assigned for use with the land telephone system.
