TtRotate [VOL] to turn OFF the power to exit the beep level adjustment mode. Setting the ringer level You can adjust the ringer level between 1 and 5, or 1 (linked) and 5 (linked). When a linked option is selected, you can adjust the ringer level by rotating [VOL]. EeWhile holding down [Lower], rotate [VOL] to turn ON the power and enter the ringer level adjustment mode. RrPush [Upper] to increase, or push [Lower] to decrease the ringer level as shown to the right. Therefore, you Can determine the current level setting by the increasing loudness of the beep that sounds.

Repeatedly push [Upper] or [Lower] to select the desired linked level. TtRotate [VOL] to turn OFF the power to exit the ringer level adjustment mode. Setting the group code number dDCTCSS tone setting The transceiver is equipped with 50 CTCSS tones. CTCSS operation enables silent standby, since you will only receive calls from group members using the same CTCSS tone. WwSet [ROTARY SELECTOR] to any channel other Rotate [VOL] to turn ON the power. rrRotate [ROTARY SELECTOR] to select the desired Channel (1 to 16) that you want to assign the CTCSS tone to. YyPush [PTT] the necessary number of times to enter the ten's digit of the desired CTCSS tone number (grey column) as shown in the list below. IiPush [PTT] the necessary number of times to enter the one's digit of the desired CTCSS tone number (grey column) as shown in the list below. nOTE: · If you make a mistake, go back to step q and follow If you want to enter "0, " do not push [PTT] in step t To turn OFF the CTCSS tone, enter "00. wwWhile holding down [PTT] , [Upper] , and [Lower] , Rotate [VOL] to turn ON the power. EeRotate [ROTARY SELECTOR] to select channel 4, then hold down [Upper] until two beeps sound. RrPush [PTT] two times to enter "2" (the ten's digit) of the number 28. [. . . ] YyPush [PTT] six times to enter "6" (the one's digit) of the number 16. Higher levels make the microphone more sensitive to the user's voice.
