Installation Caution: The RT-2500 will only operate with a nominal 12 volt negative ground battery system. It is important to carefully determine the most suitable location for your radio on your vessel. Electrical, mechanical, and environmental considerations must all be taken into account. You should select the optimum relationship among these considerations. Keep in mind the flexibility designed into the RT-2500 so that you can most conveniently use it. Features which should be considered are: The universal mounting bracket may be installed on either the top or bottom of a shelf, on a bulkhead, or for overhead mounting. The REMOTE speaker wires can be used with an auxiliary speaker. All connections are "plug-in" type for easy removal of the radio. Front fire internal speaker allows convenient in-dash mounting using the optional bracket (Black - FMB322B). Choosing a Location Some important factors to consider in selecting the location for your RT2500. Select a location that is free from spray and splash. Keep the battery leads as short as possible. Direct connection to the battery is most desirable. If direct connection can not be made with the supplied power lead, any extension should be made with #10 AWG wire. Long extensions should use larger gauge wire. Keep the antenna lead as short as possible. Long antenna leads can cause substantial loss of performance for both receiving and transmitting. Locate your antenna as high as possible and clear from metal objects. The reliable range of coverage is a direct function of the antenna height. Select a location that allows free air flow around the heat sink on the rear of the radio. Select a location well away from the ship’s compass. Auxiliary speakers also should be located away from the compass.

Engine Noise Suppression Interference from the noise generated by the electrical systems of engines is sometimes a problem with radios. The RT-2500 has been designed to be essentially impervious to ignition noise and alternator noise. However, in some installations it may be necessary to take measures to further reduce the effect of noise interference. All DC battery wires, antenna lead, and accessory cables should be routed away from the engine and engine compartment, and from power cabling carrying high currents. In severe cases of noise interference, it may be necessary to install a noise suppression kit. Contact your Dealer for more information. Antenna Considerations A variety of antennas are available from a number of quality suppliers. It is recommended you draw upon the advice of your dealer in determining a suitable antenna for your vessel and range requirements. In general, communication range is increased by using a high-gain antenna placed as high as possible above the water line. Antennas should be located away from metal objects. Antennas should not have excessively long coaxial feed cables. Antenna Selection and Installation RT-2500 has been designed to accomodate all of the popular marine VHF antennas. However, the selection and the installation of the antenna is the responsibility of the user or installer. The antenna used with this radio should be installed using the following guidelines to insure a suitable distance between the antenna and persons close by. Small whip antennas (3 dB) or smaller should be installed keeping at least three feet separation distance between the radiating element and people. Larger antennas (6 dB or 9 dB) should be installed keeping at least a six foot separation distance. No person should touch the antenna or come into the separation distance when the radio is transmitting.

Installing the RT-2500 After you have carefully considered the various factors affecting your choice of location, position the radio (with the bracket, microphone, power cord, antenna and any auxiliary cables installed) into the selected location to assure there is no interference with the surrounding items. Mark the location of the mounting bracket. Remove the bracket from the radio and use it as a template to mark the holes to be drilled for the mounting hardware. Drill the holes and mount the bracket with hardware compatible with the material of the mounting surface. Note: This HEXAGON HEAD BOLT is only for mounting the bracket with hardware. Do not use it for installing the radio in the mounting bracket. Connect the red wire of the supplied power cord to the positive (+) battery supply. Connect the black wire of the power cord to the negative (–) battery supply. The power cord is equipped with a fuse to protect the radio. Use only a six (6) ampere fast blow fuse for replacement. Connect the power cord to the keyed connector on the power "pigtail". Connect the antenna and all other auxiliary cables and accessories. Install the radio in the mounting bracket and connect all cables and accessories to the appropriate jacks and connectors. Note: Do not use any other mounting knobs than the ones enclosed. Do not insert the knobs without attaching the bracket.

Operation POWER On/Off Turn the unit On by rotating the PWR/VOL control clockwise. Adjust the volume to a comfortable level. When you turn the unit On, you will hear a beep, and the greeting message below appears on the LCD for 3 seconds. Note: When you turn On the radio for the first time after purchase, the channel 16 will appear on the LCD. Last Channel Memory The RT-2500 memorizes the last channel selected before you turn Off the radio. For example, if you turn Off the radio on CH 12, it will be on that channel when turned back On. Note: In order for the last channel to be memorized, you must have the radio on that channel for 3 seconds.

SQUELCH Turn SQ fully clockwise. This raises the “Squelch Gate” so high that only very strong signals can get through. Strong Signals Medium Signals Weak Signals Noise Turn SQ fully counterclockwise until you hear a hiss. This lowers the “Squelch Gate” so that everything gets through - noise, weak signals, and strong signals. Strong Signals Medium Signals Weak Signals Noise Turn SQ back clockwise until the hiss stops. Now the “Squelch Gate” allows only strong signals through. Strong Signals Medium Signals Weak Signals Noise
