This function is always active unless theReverse function is ON {page 51}.Due to Automatic Offset, a manually assigned offsetdirection is only effective until the frequency is changed.mg U.S.A. and Canada VersionsAutomatic Offset for the TM-251A sold in thesemarkets is programmed according to the standardARRL (American Radio Relay League) Band Plan forrepeater offset direction. You can override thisprogramming by following the “SELECTING OFFSETDIRECTION" procedure in the preceding section.Contact your national Amateur Radio association toobtain up-to-date band plans that explain band usageby mode and activity.145.5 146.4 147.0 147.6145.1 146.0 146.6 147.4 148.0 MHzHeogoeoosS: Simplex49
