REVERSE FUNCTION
The reverse function exchanges a separate receive and
transmission frequency.  So, while using a repeater, you
can manually check the strength of a signal that you
receive directly from the other station.  If the station’s
signal is strong, both stations should move to a simplex
frequency and free up the repeater.
       
To swap the transmit and receive frequencies:
Press [REV] to switch the Reverse function ON (or
OFF).
• “R” appears when the function is ON.
Note:
◆You can turn the Reverse function ON when you are operating in
Simplex Mode.  However, it does not change the Transmission/
Reception frequencies.
◆If pressing [REV] places the reception frequency outside the
allowable range, an error tone sounds and the function does not
operate.
◆If pressing [REV] places the transmission frequency outside the
allowable range, pressing Mic [PTT] causes an error tone to
sound and transmission is inhibited.
◆You cannot switch Reverse ON or OFF while transmitting.
AUTOMATIC SIMPLEX CHECK (ASC)
While using a repeater, the ASC function periodically
checks the strength of the signal you are receiving from
the other station.  If the station’s signal is strong enough
to allow direct contact without a repeater, the “
”
indicator starts blinking.
Press [REV] (1s) to switch the function ON (or OFF).
•“” appears when the function is ON.
•While direct contact is possible, “
” blinks.

MEMORY CHANNELS
In Memory Channels, you can store frequencies and
related data that you frequently use so that you do not
need to reprogram that data every time.  You can quickly
recall a programmed channel through simple operation.
A total of 200 Memory Channels (100 when using the
Memory Name function) are available for storing
frequencies, modes, and other operating conditions.
NUMBER OF MEMORY CHANNELS
The transceiver must be configured to either 200
Memory Channels without using the Memory Name
function or 100 Memory Channels with the Memory
Name function (default).

Memory Channel data in channels 100 to 199 will be erased.
◆If you change the Memory Channel capacity from 100 channels to
200 channels after storing Memory Names in those channels, the
Memory Name data will be erased.
SIMPLEX & REPEATER OR ODD-SPLIT MEMORY
CHANNEL?
You can use each Memory Channel as a simplex &
repeater channel or an odd-split channel.  Store only one
frequency to use as a simplex & repeater channel or two
separate frequencies to use as an odd-split channel.
Select either application for each channel depending on
the operations you have in mind.
Simplex & repeater channels allow:
•Simplex frequency operation
•Repeater operation with a standard offset (if an offset
direction is stored)
Odd-split channels allow:
•Repeater operation with a non-standard offset
Note:  Not only can you store data in Memory Channels, but you canalso overwrite existing data with new data.
