7 REPEATER AND DUPLEX OPERATIONS ■■ Repeater operation (Continued) For your reference: • If the Repeater tone frequency or the frequency offset is changed, the tone or offset for the Auto Repeater function is also changed. • If the offset value will cause the transmit frequency to be out of the band, "OFF" will appear on the display when [PTT] is pushed, and transmit will be inhibited. (p. 51) DDChecking the repeater input signal You can check whether another station's transmit signal can be received directly or not, by listening to the repeater input frequency. ➥➥Push [MONI DUP]C to listen on the repeater input frequency. • W hile monitoring, "BUSY" blinks. • W hile monitoring, the displayed frequency automatically changes to the transceiver transmit frequency (repeater input frequency). • W hen the other station's signal can be directly received, move to a non-repeater frequency and use simplex. (Duplex OFF) • W hile monitoring, the Attenuator function is temporarily disabled to receive a weak signal. While monitoring 49 DD1750 Hz tone burst A 1750 Hz tone is required to access many European repeaters. This function can be used only when the supplied HM-207 or optional HM-154 microphone is connected. qqSelect the FM mode. (p. 26) wwPush [PTT] on the microphone to transmit, and then push the key that the "T-CALL" function is assigned to access the repeater with a short tone burst. • See page 8 for microphone key assignment details. eeOperate normally. • The S/RF meter displays the output power level. Sending the tone burst Display Side Center Side The C, S, or D in the instructions indicate the area of the controller. C: Center S: Side D: Display
