21-410.fm Page 5 Thursday, August 5, 1999 3:36 PM PREPARATION INSTALLING THE BATTERY Your TRC-510 transceiver uses a standard 9-volt battery. For the longest life, we recommend an alkaline battery such as Radio Shack Cat. No. 23-553. Follow these steps to install or replace the battery. (illus) 1. Remove the battery compartment cover by sliding it in the direction of the arrow. 2. If necessary, remove the old battery and dispose of it properly. 3.
21-410.fm Page 6 Thursday, August 5, 1999 3:36 PM 4. Replace the cover. Replace the battery when your transceiver sounds weak or other transceivers do not receive your transmissions when they are set to the same frequency you are using. ATTACHING THE BELT CLIP To install the clip, simply slide it up into the slot on the back of the transceiver until it locks into place. (illus) To remove the clip, lift up on the locking tab and slide the clip down.
21-410.fm Page 7 Thursday, August 5, 1999 3:36 PM CONNECTING THE EARPHONE/MICROPHONE Select the rubber tip (four are supplied) that most comfortably fits your ear and push it onto the earphone/microphone. (illus) Then insert the two prongs on the TRC-510’s cord into the earphone/microphone.
21-410.fm Page 8 Thursday, August 5, 1999 3:36 PM Caution: The prongs are different sizes and fit the earphone/microphone only one way. If you cannot easily insert the prongs, turn the cord over and try again. Do not force the connection. Listening Safely To protect your hearing, follow these guidelines when you use an earphone. • Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.
21-410.fm Page 9 Thursday, August 5, 1999 3:36 PM Traffic Safety Do not wear an earphone while operating a motor vehicle or riding a bicycle. This can create a traffic hazard and is illegal in some areas. Even though some earphones are designed to let you hear some outside sounds when listening at normal volume levels, they still present a traffic hazard.
21-410.fm Page 10 Thursday, August 5, 1999 3:36 PM OPERATION You can communicate with other transceivers that operate on these frequencies: TRC-510 Channel Frequency (MHz) A B C D E 49.830 49.845 49.860 49.875 49.890 Follow these steps to use the transceiver. 1. Turn the channel selector to the desired channel.
21-410.fm Page 11 Thursday, August 5, 1999 3:36 PM Note: If using another TRC-510, simply set the channel selector on both to the same channel. If using another transceiver, set it to the same frequency as the TRC-510’s corresponding channel. 2. Set OFF/PTT/VOX to either PTT (for manual pushto-talk operation) or VOX (for voice actuated hands-free operation). (illus) If you set OFF/PTT/VOX to PTT, you can simply press PUSH TO TALK to transmit, and release PUSH TO TALK to receive.
21-410.fm Page 12 Thursday, August 5, 1999 3:36 PM • HIGH — for a low-noise area This setting means the transceiver will begin transmitting when it detects any voice or background noise. With this setting, you can speak in a softer tone of voice to make the transceiver transmit. • MID — for a moderate noise area This setting prevents moderate noises from keeping the transceiver in the transmit mode. With this setting, you can speak in a normal tone of voice to make the transceiver transmit.
21-410.fm Page 13 Thursday, August 5, 1999 3:36 PM 3. Set VOLUME HIGH/MID/LOW to LOW, insert the earphone/microphone into your ear, then set VOLUME HIGH/MID/LOW to the most comfortable listening level. (illus) 4. Set OFF/PTT/VOX to OFF to turn off the transceiver. Notes: • The TX/BUSY indicator lights green when your TRC-510 receives a sound, and lights red when it transmits a sound. (illus) • The TRC-510 cannot receive while you transmit.
21-410.fm Page 14 Thursday, August 5, 1999 3:36 PM CARE AND MAINTENANCE Your Radio Shack TRC-510 Voice-Activated 49 MHz FM Audionic Five-Channel Transceiver is an example of superior design and craftsmanship. The following suggestions will help you care for the transceiver so you can enjoy it for years. Keep the transceiver dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Handle the transceiver gently and carefully.
21-410.fm Page 15 Thursday, August 5, 1999 3:36 PM Keep the transceiver away from dust and dirt, which can cause premature wear of parts. CLEANER Wipe the transceiver with a damp cloth to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the transceiver. Use only a fresh 9-volt battery. Always dispose of an old battery promptly and properly.
21-410.fm Page 16 Thursday, August 5, 1999 3:36 PM FCC NOTICE Your transceiver might cause TV or radio interference even when it is operating properly. To determine whether your transceiver is causing the interference, turn off your transceiver. If the interference goes away, your transceiver is causing it. Try to eliminate the interference by: • Moving your transceiver away from the receiver. • Contacting your local Radio Shack store for help.
