FCC information

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

CAUTION: Changes or modifications to this device, not expressly approved by Icom Inc., could void your authority to operate this device under FCC regulations.

Hereby, Icom Inc. declares that the versions of CT-M500 which have the “CE” symbol on the product, comply with the essential requirements of the Radio Equipment Directive, 2014/53/EU, and the restriction of the use of certain hazardous substances in electrical and electronic equipment Directive, 2011/65/EU. The full text of the EU declaration of conformity is available at the following internet address: https://www.icomjapan.com/support/

Precautions

WARNING!

NEVER connect the device directly to an AC outlet. This may cause a fire or an electric shock.
NEVER connect the device to a power source of more than 16 V DC such as a 24 V battery. This connection could cause a fire or damage the device.
NEVER reverse the DC power cable polarity.

This could cause a fire or damage the equipment.

WARNING!

NEVER cut the DC power cable between the DC power connector and the fuse holder. If an incorrect connection is made after cutting, the device may be damaged.
NEVER operate the device during a lightning storm. It may result in an electric shock, cause a fire or damage the device. Always disconnect the power source and other connectors before a storm.
NEVER place the device where normal operation of the vessel may be hindered, or where it could cause bodily injury.

CAUTION: DO NOT use or leave the device in areas with temperatures below –20°C ~ +60°C (–4ºF ~ +140ºF), or in areas subject to direct sunlight, such as a dashboard.

DO NOT use harsh solvents such as Benzine or alcohol when cleaning. This could damage the equipment surfaces. If the surface becomes dusty or dirty, wipe it clean with a soft, dry cloth.
NEVER place the device in an insecure place to avoid inadvertent use by unauthorized persons.

BE CAREFUL!

The device’s rear panel may become hot when continuously using for long periods of time.
The device meets IPX7 requirements for waterproof protection*. However, once the device has been dropped, or the waterproof seal is cracked or damaged, waterproof protection cannot be guaranteed because of possible damage to the case or the waterproof seal.

Except for the DC power connector and AF Out leads.

NOTE:

Install the device more than 1 meter from the vessel’s magnetic navigation compass.
Install the device within approximately 15 meters from the transceiver or an existing access point, and in a place where there are no obstacles between the device and the transceiver.

IC-M510 and CT-M500 RF Safety warning
An internal Wireless LAN module and an antenna are supplied with the IC-M510 and CT-M500.
To comply with FCC/ISED RF Exposure for the installed Wireless LAN unit, the device should be installed and operated with a minimum distance of 20 cm between the device and all persons. No other transmitting antenna is permitted to be located within 20 cm of the device.

Disposal
The crossed-out wheeled-bin symbol on your product, literature, or packaging reminds you that in the European Union, all electrical and electronic products, batteries, and accumulators (rechargeable batteries) must be taken to designated collection locations at the end of their working life. Do not dispose of these products as unsorted municipal waste. Dispose of them according to the laws in your area.

Electromagnetic Interference

When you use a Wireless LAN, pay attention to the following:
Wireless LAN products operate in the 2.4 GHz band.
The 2.4 GHz band is also used by other devices, such as Bluetooth devices, microwave ovens, RFID systems, amateur radio stations, and so on.

When using this device near such devices, interference may occur, causing a decrease in communication speed, and an unstable connection. In such cases, use this device away from the other devices, or stop using those devices.
