FCC NOTICE

The DAY-RM25R operates on GMRS (General Mobile Radio Service) frequencies, which require a Federal Communications Commission (FCC) license. You must be licensed prior to operating on channels 1-7, 15-22 or RP15-22, DAYSTAR and RUGGED which comprise the GMRS channels of the DAY-RM25R. Serious penalties may result from unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Communications Act’s Sections 501 and 502 (amended). You will be issued a call sign by the FCC

that should be used for station identication when operating your radio on GMRS channels. You should

also cooperate by engaging in permissible transmissions only, avoiding channel interference with other GMRS users, and being prudent with the length of your transmission time

To obtain a license or ask questions about the license application, contact the FCC at 1-888-CALL FCC or go to the FCC’s website: http:// www.fcc.gov and request form 605.

Initial Installation

Mobile Installation To install the radio select a safe and convenient location inside your vehicle that minimizes danger to your passengers and yourself while the vehicle is in motion. Consider installing the unit at an appropriate position so that knees or legs will not strike it during sudden braking of your vehicle. Try to pick a well ventilated location that is shielded from direct sunlight.

CAUTION: Extreme care should be exercised when drilling into dash to avoid damage to under dash electronic ignition.

1. Install the mounting bracket in the vehicle using the supplied self-tapping screws and

at washers.

2. Position the radio, then insert and tighten the supplied hex/Phillips screws.

■ Double check that all screws are tightened to prevent vehicle vibration from

loosening the bracket or radio.

DAY-RM25R-manual.indd 3 1/8/19 7:18 AM

■ Determine the appropriate angle of the radio, using the 3 screw hole positions On the side of the mounting bracket.

DC Power Cable Connection

The vehicle battery must have a nominal rating of 12V. Never connect the radio to a 24V battery.

Be sure to use a 12V vehicle battery that has sufcient current capacity. If the current to the radio

is insufcient the display may darken during transmission or transmitting output power may drop

dramatically.

1. Route the DC power cable supplied with the radio directly to the vehicle’s battery terminals

using the shortest path from the radio. We suggest you do not use the cigarette lighter socket

as some cigarette lighter sockets introduce an unacceptable voltage drop. The entire length of

the cable must be dressed so it is isolated from heat, moisture and the engine secondary (high

voltage) ignition system/cables.

2. Conrm the correct polarity of the connections, then attach the power cable to the battery

terminals: Red connects to the positive (+) terminal and black connects to the negative (-)

terminal.

04

DAY-RM25R-manual.indd 4 1/8/19 7:18 AM

3. Connect the DC power cable to the radio’s power supply connector. Press the connectors rmly

together until the locking tab clicks.

Ext. Power jack

DC power cable

Fixed Station Operation

In order to use this radio for xed station operation you will need a separate 13.8V DC

power supply (not included).

The recommended current capacity of your power supply is 12A.

1. Connect the DC power cable to the regulated DC power supply and ensure that the

polarities are correct. (Red: positive; Black: Negative).

Do not directly the radio directly to an AC outlet.

05

DAY-RM25R-manual.indd 5 1/8/19 7:18 AM

Use the supplied DC power cable to connect the radio to a regulated power

supply. Do not substitute a cable with smaller gauge wires.

2. Connect the radio’s DC power connector to the connector on the DC power cable.

3. Press the connectors rmly together until the locking tab clicks.

Note: Before connecting the DC power to the radio be sure to switch the radio and

the DC power supply OFF.

Do not plug the DC power supply into an AC outlet until you make all connections.

DAY-RM25R-manual.indd 6 1/8/19 7:18 AM

Replacing Fuses

If the fuse blows, determine the cause then correct the problem. After the problem is

resolved replace the fuse. If newly installed fuses continue to blow, disconnect the power

cable and contact your Daystar for assistance.

Only use fuses of the specied type and rating otherwise the radio could be damaged.

Note: If you use the radio for a long period when the vehicle battery is not fully

charged or when the engine is OFF, the battery may become discharged and will not have

sufcient reserves to start the vehicle. Avoid using the radio in these conditions.

07

DAY-RM25R-manual.indd 7 1/8/19 7:18 AM

Antenna Connection

Before operating, install an ef cient well-tuned antenna. The success of your installation

will depend largely on the type of antenna and its correct installation. The radio can give excellent results if the antenna system and its installation are given careful attention.

Use a 50Ω impedance antenna and low-loss coaxial feed-line that has a characteristic impedance of 50Ω, to match the radio input impedance. Coupling the antenna to the radio via feed-lines having a impedance other than 50Ω reduces the efciency of the antenna system and can cause interference to nearby broadcast TV receivers, radio

receivers and other electronic equipment.

Note: Transmitting without rst connecting an antenna or other matched load may

damage the radio.

Always connect the antenna to the radio before transmitting. All xed stations should be equipped with a lightning arrester to reduce the risk of re, electric shock and radio

damage.

08

DAY-RM25R-manual.indd 8 1/8/19 7:18 AM

Installing the Antenna

IMPORTANT: Mount antenna up high and do not coil-up excess cable.

Antenna

Coax Cable

External Speaker Port

For the best range, only the Daystar P22353 1/2- wave antenna should be used.

Specic installation requirements vary between vehicles. Use the following guidelines

to install the antenna. Where you locate your antenna does make a difference!

1. Metal surfaces covered by berglass or vinyl may affect radio range. Avoid these locations.

2. Mount the antenna as high on the vehicle as possible. The higher the better.

3. If possible, mount the antenna in the center of whatever surface you choose.

4. Be sure the mounting location is clean and dry before installing the antenna.

5. Route the antenna cable through an accessible entry point, such as a door or trunk

opening.

6. When routing the antenna cable inside the vehicle, keep the cable away from noise

sources, such as the ignition system, gauges, etc.

7. Exercise care to prevent cable damage. Make use of existing gaskets, grommets and

weather stripping to protect the cable along its route.

Accessories Connections

External Speaker

If you plan to use an external speaker, choose a speaker with an impedance of 8Ω. The external speaker jack accepts a 3.5mm mono (2-conductor) plug. When an external speaker is connected, the radios internal speaker is automatically disabled.

DAYSTAR Repeater Channel

The Daystar repeater channel, which operates on GMRS frequencies has been

pre-programmed into your DAY-RM25R radio. Daystar will be continually installing

GMRS repeaters throughout the United States for Daystar GMRS radio owners to

use. Keep an eye on www.daystarweb.com for repeater locations (to be added

soon).

NOTE: Most repeaters* use tone codes (CTCS or DCS). When using repeaters and

tone codes, there is a short delay between the time your radio is keyed (PTT) and the

repeater decodes your transmission. When transmitting, especially through repeat-

ers, press the PTT, pause for a moment, then begin speaking. This will keep the

delay from cutting your rst few words out of the transmission.

*The DAYSTAR repeater channel has preset tones that cannot be changed.
