selected.

If the offset transmit frequency falls outside the
transmit band, transmit is inhibited until the
transmit frequency is brought within the band by at
least one of the following methods:
• Move the receive frequency further inside the
band.
• Reverse the offset direction.
■ Automatic Transmit Offset
(U.S.A. and Canada versions)
Automatic Offset for the TM-255A sold in these
markets is programmed according to the standard
ARRL (American Radio Relay League) Band Plan
for repeater offset direction. You can override this
programming by following the "Selecting Offset
Direction" procedure in the preceding section.
Contact your national Amateur Radio association
to obtain up-to-date band plans that explain band
usage by mode and activity.

145.1 146.0 146.6 147.4 148.0 MHz
S: Simplex
Automatic Transmit Offset
(European versions)
The TM-255E Automatic Offset is programmed as
follows:
144.0 145.6 145.8 146.0 MHz
S: Simplex
Note: In all versions, while Automatic Offset is ON, a manually
assigned offset is only effective until the frequency is changed.
After Automatic Offset is turned OFF, a manually assigned offset
remains effective even after the frequency is changed.
m Canceling Automatic Offset
Automatic Offset can be canceled via Menu B,
No. 78 {page 14}. The default is ON for all
versions except TM-255A (General) and TM-
455A/E.
Note: After turning ON Automatic Offset again from the OFF
status, the feature resumes functioning when a new frequency is
selected. When transferring a memory channel or the Call channel
to a VFO while Automatic Offset is ON. Automatic Offset is applied
to the VFO frequency even if this changes the offset that was
stored in the memory channel or Call channel. To avoid this and
transfer the channel data to the VFO without change, turn Menu B,
No. 78 OFF.
REVERSE FUNCTION
While FM mode is selected, each press of [REV]
switches the receive frequency and the transmit
frequency. When used while monitoring a repeater,
it's possible to check the signal strength of a station
accessing the repeater. If the station's signal is
strong, it's best to move to a simplex frequency to
continue the contact and free-up the repeater.
If reversal would place the receive frequency
outside the receive frequency range, an alarm
sounds when [REV] is pressed. No reversal
occurs.
Reverse cannot be activated while [PTT] is held
down.
When Reverse is ON, the frequency cannot be
changed.
TONE ACCESS
Each press of [TONE] toggles the Tone function ON
and OFF. Tone can only be activated when using FM
mode. When the Tone function is activated, a
subaudible tone is transmitted each time [PTT] is
pressed to transmit.
