FCC LICENSE  
A ship station license is not required for any vessel traveling in U.S. waters  
which is less than 20 meters in length. However, any vessel required to  
carry an HF SSB radiotelephone or marine satellite terminal is required to  
have a ship station license. FCC license forms can be downloaded at  
(888) 225-5322.  
Exposure To Radio Frequency Energy  
Your Midland radio is designed to comply with the following national and  
international standards and guidelines regarding exposure of human being  
to radio frequency electromagnetic energy:  
- United States Federal Communications Commission, Code of Federal  
Regulations: 47 CFR part 2 sub-part J  
- American National Standards Institute (ANSI)/Institute of Electrical &  
Electronic Engineers (IEEE) C95. 1-1992  
- Institute of Electrical and Electronic Engineer (IEEE) C95. 1-1999 Edition  
- National Council on Radiation Protection and Measurements (NCRP) of  
the United States, Report 86, 1986  
- International Commission on Non-lonizing Radiation Protection (ICNIRP)  
1998  
To control your exposure and ensure compliance with the general  
population or uncontrolled environment exposure limits, transmit no more  
than 50% of the time. The radio generates measurable RF energy  
exposure only when transmitting.  
IMPORTANT: Changes or modifications to this unit not expressly  
approved by MIDLAND RADIO CORP. could void your right to operate  
this unit. Your radio is set up to transmit a regulated signal on an  
assigned frequency. It is against the law to alter or adjust the settings  
inside the COMMUNICATOR to exceed those limitations. Any  
adjustment to your radio must be made by qualified technicians.

the batteries incorrectly will prevent the radio from operating or  
may damage the radio.  
3. Return the Battery Cover by sliding it up on the radio and push up  
the Battery Cover Latch until it locks into place. Replace the belt

CHARGINGTHE OPTIONAL BATTERY PACK  
Your NAUTICO3 is equipped for using an optional rechargeable NiMH  
battery pack which can be recharged using an AC or DC charger  
(included). Initial charge time is 24 hours with a charge time of 8-12  
hours thereafter. For maximum battery life, we recommend charging  
the NAUTICO3 when the low battery indicator comes on. Remove the  
radio from the charger when the charge time expires.  
To Charge Using Optional AC or DC Charger:  
1. Place the rechargeable Ni-MH battery pack into the radio.  
2. Connect the AC adapter into an AC wall outlet .  
3. Insert the AC adapter plug (or DC Cigarette Lighter adapter if  
charging in vehicle) into the charging jack on the side of the radio.  
1. Only use our NiMH battery pack.  
2. Do not attempt to charge alkaline batteries or any batteries  
or battery packs other than the one indicated in the manual.  
This may cause leakage and damage to the radio.  
3. For long term storage of the radio, turn the radio OFF and  
remove the batteries from the radio.
