1. Introduction

Before using your new GMRS-310 radio, please read this User’s Guide so that you can take full advantage of all the features of the radio.

The GMRS-310 is a lightweight, palm-sized radio that you can carry almost anywhere; while hunting, fishing, camping, hiking, at shopping malls, amusement parks, or sports events to keep in touch with family and friends.

Using the GMRS-310 does not require a monthly service fee - the radio can be used anywhere as allowed by the FCC.

To insure proper communications with other radios, they must be on the same channel and

CTCSS (Continuous Tone Controlled Squelch

System) sub-code as your GMRS-310.

The channel is the radio frequency wave your radio uses to transmit and receive on. The

3

CTCSS sub-code helps reduce unwanted chatter on the same radio channel, and gives you more channel choices for increased privacy.

The GMRS-310 operates on both General

Mobile Radio Service (GMRS) and Family

Radio Service (FRS) channels. Refer to the

Channel Frequency and Sub-Code Lists

(Sections 15 and 16) for channel and CTCSS sub-code choices.

2. FCC RF Exposure Compliance

The Federal Communications Commission

(FCC), with its action in General Docket 93-62,

November 7, 1997, has adopted a safety standard for human exposure to Radio

Frequency (RF) electromagnetic energy emitted by FCC regulated equipment. This radio subscribes to the same safety standard for the use of its products. Proper operation of this radio will result in user exposure far below

4

the Occupational Safety and Health Act

(OSHA) and Federal Communications

Commission limits.

3. FCC Information

The FCC requires that you be advised of certain requirements involving the use of this radio. 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 and Regulations. These rules are designed to provide reasonable protection against harmful interference with other electronic devices in a residential environment.

This equipment uses and can generate radio frequency (RF) energy. If not used in accordance with the instructions, it may cause interference to other radio communications.

However, there is no guarantee that the interference will not occur in another device’s reception (which can be determined by turning the equipment off and on). The user is

5 encouraged to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the radio and other devices

• Consult the manufacturer for technical assistance

FCC Warning: This equipment generates or uses radio frequency energy. Changes or modifications not expressly approved in writing may cause harmful interference and void the user’s authority to operate this equipment.

4. FCC Licensing Information

27 28

13. Troubleshooting

Symptom

Radio does not power on.

Audio is not heard over the speaker.

Solution

1. Confirm that batteries are installed.

2. Confirm that your batteries are fresh, and not discharged.

3. Confirm that the battery polarity is correct.

1. Press monitor and confirm that the speaker sounds.

2. Confirm that the volume has not been turned down.

3. Confirm you are on the same channel and using the same

Audio is not clear. Sub-code as the person you are calling.

Poor reception.

1. Confirm whether batteries are weak.

2. Change transmit power setting to high (tPr Hi)

3. Move closer to the person you are speaking.

4. Move to a higher elevation.

BEEP sound is not heard.

“BUSY” icon shows but

NO reception is heard.

Confirm BEEP sound has been turned on

.

Confirm that your radio’s sub-code matches the sub-code of the radio you are calling.

Continual transmission in

VOX.

VOX mode does not activate.

Confirm that your VOX Sensitivity level (SEN) is not set to lowest number (SEN 1). This level may be too sensitive for your voice or environment.

Confirm that your VOX Sensitivity level (SEN) is not set to the highest number (SEN 10). This level may not be sensitive enough for your voice or environment.

“Broken” transmissions when using VOX mode.

1. Confirm that the VOX delay time is not set to the lowest number (dLY 025). A Delay setting of 175 to 225 will generally work well for most users.
