274 REPEATER OPERATION Offset frequencyWhen communicating through a repeater, the transmit fre-quency is shifted from the receive frequency by an amountdetermined by the offset frequency.Independent offset frequencies can be set for each operatingfrequency.qPush [MAIN•BAND] to select the desired band (left or right)as the main band.• Push [MAIN•BAND] for 1 sec. then rotate the [DIAL] to select thedesired frequency band if necessary.wSelect the desired mode/channel you wish to set the offsetfrequency to, such as VFO mode or memory/call channel.• The offset frequency can be independently programmed intoeach mode or channel.e Push [SET• ] to enter set mode.rPush [SET• ] or [LOW•PRIO] until “DUP” and offset fre-quency appear.tRotate the main band’s [DIAL] to set the desired offset fre-quency.y Push [TONE•DTMF] to exit set mode.z Push [BAND] to select the desired band (left orright) as the main band.• Enter the desired frequency via the keypad if neces-sary.x Select the desired mode/channel you wish toset the offset frequency to, such as VFO modeor memory/call channel.• The offset frequency can be independently pro-grammed into each mode or channel.c Push [SET B(D-OFF)] to enter set mode.v Push [ SET B(D-OFF)] or [ ENT C(T-OFF)] until“DUP” and offset frequency appear.b Push [Y] or [Z] to set the desired offset.• Direct frequency entry from the keypad is not possi-ble.n Push [CLR A(MW)] to exit set mode.NOTE: The offset frequency can be set in a memory/callchannel temporarily. However, the set frequency is clearedonce another memory channel or VFO mode is selected.To store the offset frequency permanently, overwrite thechannel information.MAINT XDUPMPushSETBMAINT XDUPM[SET• ][LOW•PRIO]“DUP” and offset frequency appearUSING SET MODE
