To remove the battery pack: 1. Keep pressing the release buckle of the battery pack and lift the battery pack up from the transceiver’s body. Charging the Battery Pack： 1 LIFT UP 2 PUSH DOWN 1.) Connect the jack of AC adaptor into the socket of the charging cradle. 2. ) Plug the AC adaptor into the power outlet. 3. ) Insert the radio into the cradle 4.) Charge the radio with standard charger for 10-12 hours; with rapid charger for 2 hours. **Make sure the radio is turned off while charging it. **Do not forget to remove the radio from the charger when the battery is full-charged.

(Dealer Programmable) 9.) : shows battery condition. Replace or recharge the battery pack when this icon displays 2 or fewer segments of the battery. 10.) : indicates the radio is transmitting. 11.) : indicates busy channel. 12.) : indicate the strength of TX or RX signal. 13.)VOX : indicates “VOX” is activated. 14.)H or L : indicates TX output power: H means high; L means low. 15.)Channel Number: Displays channel number 01-99. Basic Operation ： Turn the radio On & OFF 1.) Rotate the PWR/VOL knob clockwise till the radio is turned on. The radio gets started to auto test for two second. During auto testing, all icons on LCD will appear. 2.) After auto testing is done, LCD will show channel number and the functions has been activated by your dealer. 3.) Rotate the PWR/VOL knob clockwise to increase its volume or counterclockwise to reduce its volume. 4.) To turn the radio off, rotate the PWR/VOL know counterclockwise to the end.click. Channel Selection RL-328 is allowed to be programmed with 99 Channels. To select a channel, press the UP/DOWN key to select a channel. Receiving RL-328 can be programmed to work channel by channel in “Open traffic” or “Group Mode” (cTCSs or DCS). Group mode prevents other users on the same channel from being heard on your radio. *Open Traffic: In this mode, you will hear all communication transmitted on the channel. When a message is received your squelch will un-mute, you will hear the message. *Group Mode: TCS/DCS (continuous Tone Code Squelch system / Digital Coded Squelch) are particular TX signaling as an access key to work a repeater (encoder) or to unlock the party’s signaling sensitive squelch. In group mode, you will receive only messages coming from parties sending a proper TX signaling. By this way, more radios share the same frequency. Monitor Press and release the “MON” button on the side of the radio to pen the squelch. This allows you to over ride the squelch and the “CTCSS” or “DCS” tones. It is useful to monitor the channel before you transmit to ensure there is no one using the channel when you have CTCSS or DCS tones programmed. Transmitting Before transmitting, monitor the channel you are using to ensure it is not busy. Keep pressing PTT button and start talking at approximately 2 inches from the MIC hole. During transmitting, the LED on the top of the radio will glow red. Release PTT button when you have finished talking. Scan The advanced scan function of RL-328 allows optionally looking for carrier or carrier with CTCSS or DCS. Your dealer can program the channels to be scanned on the scan list. *Normal Scan allows you to scan all the channels you have listed through PC programming. Press SCAN button, you will see the channel numbers cycling continuously. When the radio stops on a “Busy” channel, the SCAN mode will stop and resume after about 5 seconds. If your radio has scanned a channel on which there is a party you want to talk to, you can directly communicate with the party by pressing the PTT button. To stop scanning, press SCAN button again. *Delete a Nuisance channel allows you remove temporarily the channels which you don’t want to hear from the scan list. During scanning, when the radio is locked onto a busy channel, press “ENTER” to remove this channel from the scan list. It won’t be scanned until the radio is turned on again. Mode Setting ： Squelch Level Press MODE for one time, LCD shows And then, press UP/DOWN key to increase or decrease squelch level from 0 to 8. 0 means squelch canceling, 8 means tight squelch. Setting the radio to the tight squelch level, you can avoid unwanted signals or noise, but you may not receive a weak signal. So, it will be better for you to select the normal squelch level (default value: 3). Press ENTER to save the setting and get back to operation mode or press MODE to continue setting. VOX Sensitivity Level Press MODE repeatedly (normally twice) till LCD shows Press UP/DOWN key to adjust VOX sensitivity from 0 to 5: 0 means VOX canceling; 1 means the most sensitive (for quiet environment); 5 means the least (for noisy environment). Press ENTER to save the setting and get back to operation mode or press MODE…

FCC ID : I7ORL328V Correspondence Reference Number : 28792 731 Confirmation Number : EA915331 Subject : Reply for FCC’s Info Request dated 4/20/2005 Q1) SAR is unexpectedly low for this power. If possible please submit SAR data for output of device connected to 150 MHz or 300 MHz dipole using same device operational setup and similar phantom-spacings to device-case and/or antenna. A1) As FCC requested, we detached Antenna, and connected each dipole antenna with matching each frequency, and proceeded SAR test again.

FCC ID : I7ORL328V Correspondence Reference Number : 28869 731 Confirmation Number : EA915331 Subject : Reply for FCC’s Info Request dated 5/3/2005 Q1) Per SAR plots we assume the dipole data uses EMC3121 variable-length dipole or similar – what was dipole tuned length ? A1) Totally tuned length of dipole is 1 m. We adjusted with 150 MHz, so 50 cm + 50 cm = 1 meter, and we proceeded the test for all channel with this length. As you know, the distance from antenna to phantom is 25 mm. Q2) What is length of PTT device from end-to-end ? A2) About 20 minutes of TX. Q3) What was output power into dipole, and was that from connection to PTT device ? A3) We input 4~4.5W into dipole which comes from EUT, and we proceeded test with connection by BNC cable directly. (Attenuation : 0.45 dB) Q4) Explain how target value was derived. A4) We proceeded validation test at 300 MHz. The length of dipole antenna was 42 cm (21 cm + 21 cm. The distance from antenna to phantom was 15 mm. Please refer to “validation test block diagram” on next page. If you have further questions feel free to contact me.
