Plug the battery pack’s connector into the connector inside the battery compartment. Then place the battery pack in the compartment. Note: The connector fits only one way. Do not force it. 3. Replace the battery compartment cover, then slide LOCK to the left to lock the cover.
19-1207.fm Page 16 Friday, November 10, 2000 11:04 AM To ensure maximum range, operate the transceiver with the battery pack fully charged. As the voltage decreases, the range decreases. Caution: The supplied 12V DC, 200 mA battery charger was designed specifically for your transceiver. Use only the supplied battery charger. 1. Turn VOLUME/OFF fully counterclockwise until it clicks to turn off the transceiver. 2.
19-1207.fm Page 17 Friday, November 10, 2000 11:04 AM battery power remaining. Recharge the battery pack. 3. Unplug the AC adapter from the AC outlet after the battery is fully charged. Caution: Although the battery pack is designed to be charged using the supplied battery charger for up to a year, do not charge the battery pack longer than 24 hours at a time. CONNECTING THE ANTENNA 1. Align the slots around the antenna’s connector with the tabs on the antenna jack on the top of the transceiver.
19-1207.fm Page 18 Friday, November 10, 2000 11:04 AM 2. Press the antenna down over the jack and turn the antenna’s base clockwise until it locks into place. 3. To detach the antenna, turn the antenna’s base counterclockwise. Then lift off the antenna. Connecting an Optional Antenna Although the supplied rubber duck antenna provides excellent local reception, you can connect an optional external mobile antenna or outdoor base station antenna to your transceiver for better reception of weak signals.
-1207.fm Page 19 Friday, November 10, 2000 11:04 AM USING THE BELT CLIP The supplied belt clip lets you easily attach the transceiver to your belt. Slide the belt clip onto the tab at the back of the transceiver until it clicks. To remove the clip, pull up on its middle tab and slide it down.

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. • Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss. • Once you set the volume, do not increase it.
19-1207.fm Page 21 Friday, November 10, 2000 11:04 AM comfort might still damage your hearing. Traffic Safety Do not use an earphone with your transceiver when operating a motor vehicle or riding a bicycle in or near traffic. Doing so can create a traffic hazard and could be illegal in some areas. If you use an earphone with your transceiver while riding a bicycle, be very careful. Do not listen to a continuous broadcast.
19-1207.fm Page 22 Friday, November 10, 2000 11:04 AM USING AN EXTERNAL SPEAKER/MICROPHONE An external speaker/microphone can make it easier to use the transceiver when you clip it to your belt, so you do not have to lift the transceiver to your mouth each time you transmit. Pull up the rubber cover from the EAR and MIC jacks and plug the speaker/microphone’s 2.5 mm (3/32 inch) plug into the jacks. This automatically disconnects the transceiver’s built-in speaker and microphone.
