Oppsett

1. Installasjon av batteri

1. Juster batteripakken med sporene på baksiden av radioen.
2. Skyv batteripakken oppover til den klikker ordentlig på plass.
3. For å fjerne, trykk på utløserlåsen (hvis du har en) og skyv batteriet nedover.

2. Lader batteriet

The RT668 is powered by a 1200 mAh Li-ion battery. Use the provided charging station to charge the battery or the radio directly.

1. Koble ladestasjonen til et strømuttak.
2. Plasser radioen med batteriet installert, eller bare batteriet, i ladesporet.
3. Indikatorlampen på laderen viser ladestatusen (f.eks. rød for lading, grønn for fulladet).

3. Attaching the Earpiece

Connect the 2-pin security earpiece to the audio jack on the side of the radio for private communication.

Bruksanvisning

1. Strøm på/av og volumjustering

Rotate the top-most knob clockwise to power on the radio. Continue rotating to increase the volume. Rotate counter-clockwise to decrease volume and power off.

2. Kanalvalg

The RT668 features 16 channels. Rotate the channel adjustment knob (the second knob from the top) to select your desired channel. Ensure all radios in your group are on the same channel for communication.

3. Trykk-og-snakk (PTT)

To transmit, press and hold the large PTT button on the side of the radio. Speak clearly into the microphone. Release the button to listen.

4. VOX-funksjon (stemmestyrt sentralbord)

The VOX function allows for hands-free operation. When activated, the radio will transmit automatically when it detects your voice, eliminating the need to press the PTT button.

5. CTCSS/DCS (Continuous Tone-Coded Squelch System / Digital-Coded Squelch)

The RT668 supports CTCSS/DCS codes to filter out unwanted conversations on the same channel. When enabled, you will only hear transmissions from radios using the same CTCSS/DCS code. This ensures clear voice transmission and communication security.

6. Range Considerations

The actual communication range of two-way radios is influenced by several factors, including terrain, obstacles, radio power, antenna type, and atmospheric conditions. While manufacturers may claim extended ranges, these are often achieved under ideal line-of-sight conditions (e.g., from a mountaintop). In urban, suburban, or rural areas, the range will be significantly less due to buildings, trees, and other obstructions.

To maximize range:

• Increase Transmit Power: (In theory, doubling transmit power extends range by approximately 1.4 times the original distance).
• Improve Receiver Sensitivity: Adjust the squelch threshold and use a high-gain antenna to enhance reception.
• Operate from a Higher Position: Elevate your position to reduce obstructions.
• Hold batteriet ladet: A fully charged battery ensures optimal power output.

Vedlikehold

1. Generell omsorg

The Retevis RT668 is designed with a technical PC case for durability and is water-resistant. However, proper care is essential for longevity.

• Avoid exposing the radio to extreme temperatures, direct sunlight for prolonged periods, or harsh chemicals.
• Rengjør radioen med en myk klutamp klut. Ikke bruk skurende rengjøringsmidler eller løsemidler.
• Ensure the battery contacts are clean and dry.

2. Batteripleie

• Do not disassemble, dispose of in fire, or short-circuit the battery terminals.
• Bruk kun den angitte laderen for batteripakken.
• Ved langtidslagring, lad batteriet til omtrent 50 % og oppbevar det på et kjølig og tørt sted.

Feilsøking

1. Ingen strøm

• Sjekk om batteriet er riktig installert og ladet.
• Sørg for at av/på-knappen er vridd med klokken til «PÅ»-posisjonen.

2. Kan ikke sende eller motta

• Verify that all radios are on the same channel.
• Check if CTCSS/DCS codes are correctly matched between radios.
• Sørg for at du er innenfor effektiv kommunikasjonsrekkevidde.
• Sjekk om det er hindringer mellom radioene.

3. Dårlig lydkvalitet

• Juster volumnivået.
• Check the squelch level; a higher squelch level might filter out weak signals.
• Sørg for at mikrofonen og høyttaleren ikke er blokkert.
• Move to an area with fewer obstructions or closer to the other radio.
