Transmit Battery Saver
Always use the lowest transmitter power necessary
to maintain reliable communications (this may be the
law in your country). As described on page 18, there
are four T
X
power levels: high, low 1, low 2 and low
3. Activating TX Save can reduce transmitter current
drain even further, by reducing power output when a
full-scale signal is sensed on the receive frequency.
TX Save can be turned on as follows:
Hold the knob down for second, then release it
and turn it to display
Press the knob
momentarily, then turn it to select
(or
to
deactivate).
Press the
to exit.

Notice that the
SAVE
indicator is displayed
during
transmission
when the TX Save function is activated.
Regardless of whether you use the TX Save feature,
remember that the current drain of the I setting is
much less than the
setting, so it is good to
develop the habit of always using the lowest setting
possible, switching to high power only when low
power fails to get through.
If you need better range, consider using a higher gain
antenna instead of high power (the effect on trans-
missions the same, but receive performance im-
proves as well). Make sure any external antenna is
designed for 50 ohms impedance at the operating
frequency.
Beeper Disable
BEEP-
The keypad beeper draws several milliamperes, so
you may want to disable it if you need to conserve
power while using the controls a lot. Note, however,
that you will lose the audible feedback that indicates
key functions and errors.
To disable the beeper:
Hold the knob down for second, then release it
and turn it to display
Press the knob
momentarily, then turn it to select
(or
to
disable).
Press the PTP to exit.

LED Disable
The LED draws about 15 milliamperes when the
squelch is open, and when transmitting. However,
you may not need it: the
of the LED is
duplicated by the icon at the right side of the
display when the squelch is open, and the
always shows the TX power level when transmitting.
You can disable the LED to conserve power:
Hold the knob down for second, then release it
and turn it to display
Press the knob
momentarily, then turn it to select
(or
to
enable).
Press the PTT to exit.
