Thetransceiver has two inhibiting conditions, repeater and busy.q While pushing and holding [YY] and [ZZ], turn the power ONto enter INITIAL SET MODE.w Push [YY] or [ZZ] several times until “RLO” appears.e Rotate [VOL] to select the repeater lockout function to“RP,” “bU” or OFF.• “RP”: Transmit is inhibited when a signal with un-matched sub-audible tone is received.• “bU”: Transmit is inhibited when a signal is received.r Push [✱ ENT] (or [CLR]) to exit INITIAL SET MODE.USING INITIAL SET MODE
