7 AUXILIARY FUNCTIONS

TRANSMITTING

SPEECH PROCESSOR

The speech processor functions by leveling the large
fluctuations in your voice that are present when you

speak. This leveling action effectively raises the
average transmit output power resulting in a more
understandable signal when operating SSB or FM.

Particularly under poor receive conditions, you will
notice that using the speech processor makes it

easier to be heard by distant stations.

Press [PROC] to toggle the Speech Processor ON or

OFF.

• "PROC" appears when the function is ON.

TIME-OUT TIMER (TOT)

It is sometimes necessary or desirable to restrict a

single transmission to a specific maximum time. This
feature can be useful when accessing repeaters to
prevent repeater time-outs as a result of a single
transmission that is longer than the maximum
permitted time. The Time-out Timer also prevents
your transceiver from damage due to excessive

uninterrupted transmissions. If you are trying to
conserve battery power, TOT helps with that task too.

Activate TOT via Menu B, No. 59 {page 14} anytime
you wish to limit your transmit time. There are 5

different timer values available. The default for the
function is OFF. When TOT times out, the transceiver
beeps and automatically returns to Receive. To

resume transmitting, release and then press [PTT]
again.

OPERATOR CONVENIENCES

MICROPROCESSOR RESET

If your transceiver seems to be malfunctioning,

initializing the microprocessor and its memory may
resolve the problem.

Partial Reset

Do a Partial Reset if a button or control does not

function according to the instructions provided in
this manual. A Partial Reset does not erase any
data in memory channels.

Press [A/B]+ POWER ON.

Full Reset

Do a Full Reset if you want to erase all data in ail
memory channels or a Partial Reset does not

correct a problem you are experiencing.

Remember that a Full Reset requires that you re

enter any memory channel data again after the
initialization if you wish to use those channels. On
the other hand, initialization is a quick way to erase
all data from all channels.

Press [MR]+ POWER ON.
